QUESTION 1Which of the following are unique features of ESX (as opposed to ESXi)? (Choose two.)

A. ESX is an embedded architecture.B. The root account can be locked down.C. ESX has a smaller security footprint compared with ESXi.D. ESX supports the installation of third-party management and backup agents.E. ESX is managed with the Service Console, running Red Hat Enterprise Linux 5.2.

Correct Answer: DESection: 1. Planning, Installing, and Upgrading VMware ESX/ESXiExplanation

Explanation/Reference:ESXi has the embedded architecture and supports the locked-down root account (notESX). ESXi also has a smaller security footprint as it does not include the Service Consolemanagement interface as ESX does.

QUESTION 2You want to quickly prototype a demo virtual machine and show your demo to a customeron your laptop (which runs Windows XP Pro). The VM needs to run with two processors,and you would like to be able to take multiple snapshots for rollback or demo purposes.You will occasionally have to modify the VM for various customer demos (changing theamount of RAM allocated to the VM at the very least). Finally, you decide it would be niceto be able to have the product capture video of the VM to leave with the client when thedemo is finished.

Which product would best provide your needs as you build this VM?

A. VMware PlayerB. VMware FusionC. VMware ServerD. VMware WorkstationE. vSphere ESX/ESXi

Correct Answer: DSection: 1. Planning, Installing, and Upgrading VMware ESX/ESXiExplanation

Explanation/Reference:Workstation is an inexpensive choice that will run on a laptop and that will allowfor multiple snapshots and video capture. Player won’t allow you to reconfigure the VM,Server does not support either multiple snapshots or video capture, and Fusion runs onIntel Macs only.

QUESTION 3Which of the following should you back up on an ESX 3.5 server before performing anupgrade to ESX 4.0? (Choose two.)

A. VMFS SAN LUNsB. vCenter custom alarm scriptsC. Locally stored virtual machine filesD. System configuration files in the /etc directoryE. System configuration files in the /config directory

Correct Answer: CDSection: 1. Planning, Installing, and Upgrading VMware ESX/ESXiExplanation

Explanation/Reference:Backing up an ESX server includes local system configuration files in the /etc directory,custom scripts stored on the ESX server, and locally stored VMFS file systems (includingvirtual machine files, templates, and ISO images). vCenter scripts would be backed upas part of vCenter upgrading, not ESX upgrading, and the contents of SAN LUNs would bebacked up as a matter of course by the SAN administration team.

QUESTION 4What is the minimum version of ESX that is supported for upgrading to ESX 4.0?

A. 2.1B. 2.5C. 2.5.5D. 3.0E. 3.5

Correct Answer: CSection: 1. Planning, Installing, and Upgrading VMware ESX/ESXiExplanation

Explanation/Reference:ESX 2.5.5 can be upgraded to ESX 4.0 if the /boot partition was built at least 100 MB insize. If you chose the default 50 MB /boot partition for ESX 2.5.5, you will need to upgradeto ESX 3.x first and then upgrade to ESX 4.0. All properly installed versions of ESX 3.x canbe upgraded to ESX 4.0.

QUESTION 5Which of the following describe valid options when setting up licensing on an ESX/ESXi 4.0 server? (Choose two.)

A. You must specify a license server.B. You can enter a 25-character license code.C. You can use a 30-day evaluation license.D. You can use a 60-day evaluation license.E. ESXi is not a licensed product and so there are no licensing options for ESXi.

Correct Answer: BDSection: 1. Planning, Installing, and Upgrading VMware ESX/ESXiExplanation

Explanation/Reference:ESX/ESXi 4.0 now use a 25-character license code. Although a license server maybe specified for backward compatibility with ESX 3.x/VC 2.x, the license server is notrequired for 4.0 only environments. Finally, a 60-day evaluation license is available.

QUESTION 6After a standard installation, how can you access an ESX Service Console remotely?(Choose three.)


A. Using TelnetB. Via an SSH ClientC. Via a web browserD. Using the vSphere (GUI) ClientE. Using Microsoft Remote Desktop

Correct Answer: BCDSection: 1. Planning, Installing, and Upgrading VMware ESX/ESXiExplanation

Explanation/Reference:Remote access to the Service Console is fairly limited and only secure access isenabled by default. The use of Telnet is not supported (in fact, Telnet is not even included inthe installation CD/DVD), and there is no GUI desktop to connect to with Microsoft RDP.

QUESTION 7How can you manage an ESXi server? (Choose three.)

A. Using the Service ConsoleB. By direct login with the vSphere (GUI) ClientC. From a vCenter login with the vSphere (GUI) ClientD. Using the vMA management virtual applianceE. By remotely logging in using SSH

Correct Answer: BCDSection: 1. Planning, Installing, and Upgrading VMware ESX/ESXiExplanation

Explanation/Reference:ESXi has no Service Console and so does not support a Service Console interfaceor SSH logins.

QUESTION 8When you’re booting an ESX/ESXi server from a SAN, which of the following apply?(Choose two.)

A. Both ESX and ESXi support booting from an iSCSI SAN.B. An HBA that is supported for boot from SAN is required.C. The HBA BIOS must be properly configured to support boot from SAN.D. You must check the installation manual as installing a boot-from-SAN ESX server is

substantially different from installing to a local disk.E. The LUN must be masked so as to be presented to all ESX servers in the DRS/HA

cluster as ESX requires shared storage.

Correct Answer: BCSection: 1. Planning, Installing, and Upgrading VMware ESX/ESXi

Explanation

Explanation/Reference:Boot from SAN specifically requires supported HBA cards capable of booting from aSAN LUN, and the HBA card must be properly configured before installing ESX. ESXi doesnot support booting from iSCSI as of this writing. The installation of ESX is substantiallythe same whether booting from local disk or from a SAN LUN. Finally, the LUN should bemasked so that only the booting ESX server has access to it.

QUESTION 9Which of the following partitions are not created by default when installing ESX 4.0? (Choose two.)

A. /tmpB. swapC. /homeD. /bootE. /var/log

Correct Answer: ACSection: 1. Planning, Installing, and Upgrading VMware ESX/ESXiExplanation

Explanation/Reference:Although they may be (optionally) created during the installation, there is no needfor the /tmp and /home partitions on an ESX server. Further, the swap and /var/logpartitions are now created in a VMFS with ESX 4.0.

QUESTION 10The development group has supplied you with a VM preloaded to run a customer demo.You have no need to reconfigure this VM and, in fact, development would prefer youalways run the demo in the VM as delivered. Which product would be the best fit forrunning this VM?

A. VMware PlayerB. VMware FusionC. VMware ServerD. VMware WorkstationE. vSphere ESX/ESXi

Correct Answer: ASection: 1. Planning, Installing, and Upgrading VMware ESX/ESXiExplanation

Explanation/Reference:VMware Player will allow you to run the VM from development as is without allowingyou to make any modifications.

QUESTION 11Which of the following describe techniques or VMkernel engineering design used to hardena vSphere 4.0 environment? (Choose three.)

A. VMkernel memory hardeningB. VMs share the same memory silos or worldsC. VMs are granted direct access to physical hardwareD. VMkernel module integrity via digital signatures

E. Resource limits and reservations as prevention against DoS attacks

Correct Answer: ADESection: 1. Planning, Installing, and Upgrading VMware ESX/ESXiExplanation

Explanation/Reference:VMkernel memory hardening is accomplished via randomization of memoryaddresses for driver modules as they are loaded (ASLR). In addition, VMkernel modulesare digitally signed and VM limits and reservations can serve as a cap on physical resourceconsumption. VMs do not share memory silos/worlds and are not granted direct access tothe server’s physical hardware.

Exam B

QUESTION 1Which distributed vSwitch port binding policy essentially mimics the dynamic binding of astandard vSwitch?

A. PrimaryB. StaticC. DynamicD. Ephemeral

Correct Answer: DSection: 2. Configuring ESX/ESXi NetworkingExplanation

Explanation/Reference:Ephemeral binding on a distributed vSwitch is the same as the dynamic binding used onstandard vSwitches.

QUESTION 2What is the default number of dvUplink ports on a newly created distributed vSwitch?

A. 4 per ESX/ESXi hostB. 8 per ESX/ESXi hostC. 4D. 8E. 16

Correct Answer: ASection: 2. Configuring ESX/ESXi NetworkingExplanation

Explanation/Reference:A distributed vSwitch, by default, supports a maximum of 4 dvUplinks (physical NICadapters) per ESX/ESXi host.

QUESTION 3You would like to have a VM scan and capture all packets on the virtual switch it isconnected to. Which security policy would you have to set to allow this?

A. Forged TransmitsB. MAC Address ChangeC. PromiscuousD. Port ScanE. Protocol Analyzer Mode

Correct Answer: CSection: 2. Configuring ESX/ESXi NetworkingExplanation

Explanation/Reference:Putting a vSwitch port group into Promiscuous mode allows all VMs connected tothat port group to put their vNICs into Promiscuous mode as well, thereby allowing forthe capture of all packets on their VLAN.

QUESTION 4

You have a vSwitch with 56 ports, all of which are in danger of being used up by theincreasing number of VMs you are attaching to the vSwitch. In the vSphere Client GUI,you increase the number of ports on the switch to 120. However, after increasing the portcount, you are unable to add any additional VMs to the switch. Why?

A. You have to remove all current VMs from a virtual switch before changing the numberof ports.

B. The ESX server needs to be rebooted.C. Changing the port count on virtual switches is not supported.D. You must power off all VMs using the virtual switch to change the number of ports.

Correct Answer: BSection: 2. Configuring ESX/ESXi NetworkingExplanation

Explanation/Reference:Changing the number of ports on a virtual switch requires that an ESX server berebooted before the changes can take effect. Using VMotion to move the VMs to anotherESX host first, although not required, would allow for the change in a nondisruptive wayto the VMs.

QUESTION 5Which of the following may be present on a physical switch but not a virtual switch?

A. TeamingB. Spanning TreeC. Traffic ShapingD. Private VLANs


Explanation/Reference:the Spanning Tree protocol.

QUESTION 6When would you choose Virtual Port ID-based load balancing on a teamed virtual switch?

A. You need to guarantee all virtual machines can individually have access to the combinedbandwidth on the teamed switch.

B. You don’t have any particular per-virtual machine bandwidth requirements and youwant to use the lowest-cost load-balancing policy.

C. You want to ensure virtual machines have the maximum opportunity to failover toredundant physical NICs.

D. You need to maximize the security of the virtual switch.

Correct Answer: BADBADADBAACDDAAACASection: 2. Configuring ESX/ESXi NetworkingExplanation

Explanation/Reference:have a single virtual NIC) will only have access to a single physical NIC’s bandwidth at anymoment in time. To simultaneously utilize the bandwidth of multiple physical NICs, youwould have to use the IP-based load-balancing policy. The Virtual Port ID load-balancingpolicy also has the benefit of being the default and, generally, the lowest “cost” in terms of

VMkernel management effort.

QUESTION 7How many ESX/ESXi hosts can be connected to a distributed virtual switch?

A. 8B. 16C. 32D. 56E. 64

Correct Answer: ESection: 2. Configuring ESX/ESXi NetworkingExplanation

Explanation/Reference:Distributed virtual switches support a maximum of 64 ESX/ESXi hosts each.

QUESTION 8Which of the following settings is exclusive to a distributed vSwitch?

A. Private VLANsB. Port BlockingC. Egress Traffic ShapingD. VLAN TrunkingE. Port Group Override Settings

Correct Answer: ABDESection: 2. Configuring ESX/ESXi NetworkingExplanation

Explanation/Reference:Egress (outbound) traffic shaping is supported on both standard vSwitches as wellas distributed vSwitches. All of the other answers are unique to the new vSphere distributedvSwitches.

QUESTION 9Which of the following is not unique to a distributed vSwitch?

A. Virtual machine network statistics that follow the VM after a VMotion migrationB. Third-party plug-in supportC. Egress traffic shapingD. Per-VM port blocking

Correct Answer: CSection: 2. Configuring ESX/ESXi NetworkingExplanation

Explanation/Reference:Distributed vSwitches add ingress traffic shaping (egress traffic shaping has been partof the standard vSwitch for a long time), per-VM port blocking capabilities, VM networkstatistics that follow the VM across VMotion migrations, and third-party plug-in support.

QUESTION 10How could you have a virtual machine utilize the bandwidth of two or more physical NICson a vSwitch?

A. Add additional virtual NICs to the virtual machine.B. Use IP-based load balancing on the teamed virtual switch.C. Use virtual port–based load balancing on the teamed virtual switch.D. Use Source MAC–based load balancing on the teamed virtual switch.

Correct Answer: ABSection: 2. Configuring ESX/ESXi NetworkingExplanation

Explanation/Reference:Adding a second virtual NIC to a virtual machine allows, with any of the load-balancingpolicies on a teamed switch, the virtual machine to utilize multiple physical NICs up to thenumber of virtual NICs you have added to the virtual machine. Using the IP-based load balancingallows for virtual machines with a single virtual NIC to use multiple physical NICS.

QUESTION 11Which of the following would not trigger the VMkernel to send out a Notify SwitchesRARP packet to a physical switch?

A. Powering on a VMB. Cold migration of a VMC. Hot migration of a VMD. Change in uplink status of a physical NIC


Explanation/Reference:If you have Notify Switches set (the default), the VMkernel will send anRARP packet to notify a physical switch whenever there is a need for the physical switchto update its internal MAC table. VMotion, powering on a VM, and physical NIC uplinkstatus changes can all result in this RARP notification being sent. With cold migration,the VM isn’t powered on; no packets will be sent from the VM until it is powered on, andso there is no need to notify the physical switch.

Exam C

QUESTION 1In which of the following cases can you get away with specifying (checking the box for)Read-Only when creating an NFS datastore on an ESX server? (Choose two.)

A. The NFS datastore will contain running VMs.B. The NFS datastore will contain Installer ISO images.C. The NFS datastore will be a secondary location for a VM’s VSWP file.D. The NFS datastore will contain templates (which are periodically updated).E. The NFS datastore will contain templates (which are not updated).

Correct Answer: BESection: 3. Configuring ESX/ESXi StorageExplanation

Explanation/Reference:Any time you need to modify data on the NFS datastore, you should not check theRead-Only box. Further, if the NFS server is serving the datastore as read only (export fileproperties, for example), you should check the Read-Only box.

QUESTION 2Which of the following are techniques for masking LUNs in a Sphere 4.0 ESX environment?(Choose two.)

A. Setting a mask (permission list/ACL) on the fiber switchB. Setting a mask (permission list/ACL) on the SAN arrayC. Setting a mask (vCLI) on the ESX server via the vMA applianceD. Setting a mask (permission list/ACL) on the ESX server using the vSphere Client

Correct Answer: BCSection: 3. Configuring ESX/ESXi StorageExplanation

Explanation/Reference:Setting a mask on the SAN and setting a mask on an ESX server via the vCLI areboth techniques for masking SAN LUNs in a vSphere 4.0 ESX environment.

QUESTION 3Which of the following is not used as part of an ESX/NFS data storage implementation?

A. NFS NAS applianceB. Linux NFS serverC. Ethernet network infrastructureD. Hardware initiator with TCP Offload Engine (TOE)E. Virtual switch with VMkernel storage port configured

Correct Answer: DSection: 3. Configuring ESX/ESXi StorageExplanation

Explanation/Reference:The administrator can choose between a NAS appliance and a Linux NFS server. Ethernetnetwork infrastructure and a virtual switch are both necessary components of an NFS datastorage network on an ESX server. There is no need for, and the VMkernel will not use, theTOE engine in an NFS storage network (a TOE engine is used in an iSCSI environment with a

hardware initiator).

QUESTION 4You have a single LUN on an iSCSI array. You have configured a virtual switch to supportmultipathing of VMkernel ports for use in a software-initiated iSCSI environment by havingthe virtual switch bound to two physical network adapters. Each VMkernel port is configuredto use a single physical adapter only, with a second adapter configured as Unused. Further,each VMkernel port uses a different adapter as its primary adapter. Which of the followingwould represent the VMkernel ports used in this switch?

A. vmhba32:C0:T0:L19 and vmhba33:C0:T0:L19B. vmhba32:C0:T0:L19 and vmhba32:C1:T0:L19C. vmhba32:C0:T0:L19 and vmhba32:C0:T1:L19D. vmhba32:C0:T0:L19 and vmhba32:C0:T0:L20

Review Questions 169

Correct Answer: BSection: 3. Configuring ESX/ESXi StorageExplanation

Explanation/Reference:Binding individual physical outbound adapters to respective VMkernel ports in the samevirtual switch may result in different C values in the vmhba VMkernel port names. A singlevirtual switch will use a single vmhba instance (vmhba32, for example). Here, the multipathingis being configured on the virtual switch on the ESX server; the T (iSCSI target) isnot part of the answer. As the path is being set up for a single LUN, the L (LUN) numberwill be the same.

QUESTION 5What are the primary factors used to determine whether to use a software or a hardwareinitiator when setting up an iSCSI array on an ESX 4.0 server? (Choose two.)

A. The number of PCI slots you have in your physical serversB. The cost savings when using software initiatorsC. Whether you have 1 GB or 10 GB Ethernet NICs in your ESX serversD. The added performance of using hardware initiatorsE. The number of LUNs you are using

Correct Answer: BDSection: 3. Configuring ESX/ESXi StorageExplanation

Explanation/Reference:The decision to go with a software or a hardware initiator is primarily one of costversus performance. Software initiators, especially in large deployments, can result in significantcost savings. Hardware initiators may result in increased data throughput to theSAN and reduced CPU load on the ESX servers as the hardware HBA offloads much of theiSCSI data packet processing.

QUESTION 6When you delete a VMFS datastore, which of the following will happen?

A. Any running VMs will immediately crash.B. All data contained within should be considered irretrievably lost.C. If the VMFS contains extents, you will be asked which extent(s) to remove.D. The VMFS automatically creates a backup mirror of the data in the datastore before

deletion.


Explanation/Reference:The VMFS deletion wizard will not let you delete a VMFS datastore with running VMsas the running VMs will have created exclusive locks on their virtual disk files in the VMFS.Deletion, once confirmed, is immediate and permanent, and should be considered irreversible.Deletion of a VMFS removes all extents; you cannot remove individual extents from anextended VMFS. Finally, VMFS does not create backup or mirrors at any time. Backing updata is (still) entirely your responsibility.

QUESTION 7Which of the following is a valid IQN name for an ESX server?

A. iSCSI.1998-01.com.vmware.esx29-7c79e548B. iqn.1998-01.com.vmware:esx29-7c79e548C. iSCSI-iqn.com.vmware.1998-01:esx29-7c79e548D. iqn.1998-01.vmware.com:esx29-7c79e548E. iSCSI.vmware.com.1998-01.esx29-7c79e548


Explanation/Reference:Valid IQN names are of the form iqn.yyyy-mm.naming-authority:unique-name. Thenaming authority is in reverse DNS domain name notation. The unique name, by default,contains a unique hex string at the end.

QUESTION 8Which of the following is not an iSCSI storage maximum in vSphere 4.0?

A. 256 LUNs per ESX hostB. 16 paths to each LUC. 4 hardware initiatorsD. 1024 total paths


Explanation/Reference:There are only 8 paths to a LUN supported in vSphere 4.0.

QUESTION 9Which of the following are true statements about LUN discovery? (Choose two.)

A. At boot time, an ESX server scans LUNS 1–256.B. At boot time, an ESX server scans LUNS 0–255.C. After the initial boot, an ESX server does not automatically scan for LUNs at boot time.D. Setting Disk.MaxLUN to 30 would change scanning to stop at LUN number 30.E. LUNs can be scanned from the GUI and from the command line.


Explanation/Reference:LUN numbering starts at 0 (zero), so ESX would scan LUNs 0–255 at boot time.Disk.MaxLUN sets the maximum number of LUNs to scan, not the maximum LUN number.

QUESTION 10Which of the following are not supported features when using NFS datastores on anESX 4.0 server? (Choose two.)

A. 10 GB Ethernet NIC cardsB. TCP Offload Engine (TOE)C. Jumbo framesD. Linux NFS servers (you must use an NFS NAS appliance)E. Teamed virtual NICs


Explanation/Reference:The presence of TOE on a NIC, although it won’t break an NFS datastore implementation,is not necessary and TOE will not be used.

QUESTION 11Which of the following describe connecting ESX servers to FC storage in support of runningVMs? (Choose two.)

A. Multiple HBAs per LUN may be used simultaneously to improve throughput.B. ESX servers use NPIV to track WWPN addresses per VM.C. Traditional SAN tools can be used to monitor per-VM performance statistics.D. Physical HBAs can be configured or queried by VMs.E. Multipathing HBAs is done on the ESX server, not within VMs.


Explanation/Reference:ESX only supports a single active HBA per LUN at any moment in time. ESX serversuse NPIV to track individual VM storage usage. This can be useful for storage performanceanalysis. Traditional SAN tools have no idea of VMs and so are generally not used to monitorper-VM statistics. The VMkernel does not allow a VM to query any hardware. In fact,the VMkernel does not present physical HBAs to VMs in any way. Thus, because the VMkerneldoes not present HBAs to VMs, there is no way a VM can configure physical multipathingin a SAN environment. This is done on the ESX server.

Exam D

QUESTION 1If you want to remove the Getting Started tabs from the display shown here, what wouldyou do?

Exhibit:

A. Change a vCenter server preference.B. Change an ESX server preference.C. Nothing; the Getting Started tabs only display when you are in evaluation licensing

mode and automatically disappear when you properly license vCenter.

D. Change a vSphere Client preference.E. Nothing; the Getting Started tabs cannot be removed.

Correct Answer: DSection: 4. Installing and Configuring vCenter ServerExplanation

Explanation/Reference:The display of the Getting Started tabs is a preference set in the vSphere Client GUI.Each client user, therefore, can show or hide these tabs.

QUESTION 2Which of the following solutions will not provide high availability or failover in the event ofa vCenter server crash?

A. vCenter Server HeartbeatB. VMware FTC. VMware HAD. MSCSE. Cold cloning the vCenter server

Correct Answer: BSection: 4. Installing and Configuring vCenter ServerExplanation

Explanation/Reference:VMware FT, as of this writing, only supports single vCPU VMs and does not supportphysical servers at all. So, even assuming vCenter is running on a VM, FT won’t workbecause vCenter requires a minimum of two CPUs.

QUESTION 3Which of the following is supported across multiple datacenter objects in the vCenterinventory?

A. VMotionB. HAC. Delegation of controlD. Deploying VMs via templatesE. FTF. Distributed virtual switches


Explanation/Reference:Deploying a VM using templates is the only option supported across multiple datacenters.Datacenters and their restrictions are important in the design of your vCenter inventory.

QUESTION 4Which two of the following database products are not supported with vCenter 4.0?

A. SQL Server 2008B. SQL Server 2000C. IBM DB2

D. Oracle 11gE. Oracle 9i

Correct Answer: BESection: 4. Installing and Configuring vCenter ServerExplanation

Explanation/Reference:vCenter 4.0 requires SQL Server 2005 SP1 or better, or Oracle 10g Release 2 or better.IBM DB2 support is included as of vCenter 4.0 update 1.

QUESTION 5What is the maximum number of VMs per ESX 4.0 host?

A. 80B. 128C. 192D. 256E. 320

Correct Answer: ESection: 4. Installing and Configuring vCenter ServerExplanation

Explanation/Reference:With each ESX release, the maximum number of VMs supported on an ESX server hasincreased. At ESX 4.0 the current maximum is 320. Remember also, if you are runningmultiple vCPU VMs, the maximum number of vCPUs per ESX 4.0 host is 512.

QUESTION 6Which of the following are two reasons to join two vCenter servers via Linked Mode?

A. You want to be able to view inventory information across vCenter instances.B. You want to use HA to fail over to an ESX host in another vCenter.C. You want to manage vCenter 2.0 from a vCenter 4.0 server.D. You want to exceed the maximum number of ESX hosts manageable by a single

vCenter instance.E. You need to connect 20 vCenter instances together.

Correct Answer: ADSection: 4. Installing and Configuring vCenter ServerExplanation

Explanation/Reference:VMware HA is not supported across multiple vCenter instances via Linked Mode.Linked Mode requires vCenter 4.0 or better and supports a maximum of 10 linkedvCenter instances.

QUESTION 7A user has the No Access role assigned to the root object in the vCenter inventory. Furtherdown in the inventory, this same user has the Administrator role assigned to a datacentercalled QA. Assuming these are the only two permissions related to this user, when this userlogs into vCenter, what level of access will he have in the QA datacenter?

A. None, because of the No Access permissionB. Administrator-level access, because of the Administrator role

C. He will not be able to log in because No Access at the root object prevents login access.D. He will have Administrator access on the entire inventory as Administrator permission

takes precedence over No Access permission.E. vCenter will not allow you to define these sorts of conflicting permissions.



Explanation/Reference:With conflicting user permissions defined at different levels in the inventory hierarchy,the lower-level permission overrides any higher-level permission. This is the case whether thelower-level permission grants more or less access than the upper-level permission. Grant conflictingpermissions with care!

QUESTION 8Using the vCenter sizing calculator, which of the following is shown to have the largestimpact on the size of the vCenter database at the end of a year?

A. The number of physical hosts being managedB. The number of virtual machines being managedC. Changing the statistics level from 1 to 4D. Changing the 5-minute interval duration from being saved for one day to five daysE. Disabling (by deselecting) the Save For 1-year statistics level

Correct Answer: CSection: 4. Installing and Configuring vCenter ServerExplanation

Explanation/Reference:Increasing the statistics level from level 1 (basic) to level 4 (all metrics supported byvCenter) has a significantly larger impact than any of the other factors. Of course, if youcombine all of these options, the database can easily grow by over a factor of 10 from thedefault estimated size.

QUESTION 9UserA is a member of GroupA. GroupA has been assigned the role Read Only applied tothe datacenter Training in the vCenter inventory. In addition, UserA has been assigned therole VM Power User applied to the same inventory object, Training. When UserA logs intovCenter, what will she be able to do with the Training datacenter?

A. UserA will have Read Only role access.B. UserA will have Administrator role access.C. UserA will not be able to log into vCenter as she has conflicting user and group

permissions.D. UserA will have VM Power User role access.E. UserA will only have access to the Training datacenter if she also has at least Read

Only role access explicitly granted at the Training datacenter object’s parent object.


Explanation/Reference:When user and group permissions collide on the same object, the user permission takes

precedence.

QUESTION 10UserA is a member of two groups, GroupA and GroupB. UserA has no user-level permissionsassigned in the vCenter inventory. Both GroupA and GroupB have permissions assigned tothe same vCenter inventory object; GroupA is assigned the VM Power User role and GroupBthe Read Only role. Which of the following describes what UserA will be able to do with theinventory object these group permissions have been assigned to?

A. UserA will get the least permissions: GroupB, Read Only.B. UserA will get the most permissions: GroupA, VM Power User.C. UserA will get the logical sum of the permissions of both GroupA and GroupB.D. You cannot apply two different group permissions on the same vCenter inventory object.E. UserA will not be able to log in as conflicting permissions are resolved by locking out a

user’s access.


Explanation/Reference:When you have two groups, each with different permissions applied to the same vCenterinventory object, the permissions are logically added.

QUESTION 11When you add an ESX/ESXi host to vCenter, you add it using its ________.

A. IP addressB. IPv4 and IPv6 addressesC. Fully qualified domain nameD. Short hostnameE. Ethernet MAC address

242 Chapter 4 n Installing and Configuring vCenter Server


Explanation/Reference:Although you can add ESX hosts to vCenter using either their short names or theirIP addresses, using FQDNs is preferable. Some of the vSphere features require FQDNs orwork better if you have added the ESX host using its FQDN. Get in the habit of addingESX hosts to vCenter using their FQDNs.

QUESTION 12Which of the following are default permissions on the root object of an ESX server that hasnot been added to vCenter? (Choose three.)

A. The dcui user has Administrator role access.B. The Administrator user has Administrator role access.C. The root user has Administrator role access.D. The vpxuser user has Administrator role access.E. The root user has Root role access.F. The vpxuser user has Root role access.

QUESTION 6Which of the following statements are true about a VM’s swap file?

A. The VSWP file always takes an amount of physical disk space equal to the VM’s RAMlimit minus its reservation.

B. The VSWP file can be located on a local datastore for performance or space-saving

reasons.C. The location of the VSWP file is irrelevant to the proper functioning of VMotion.D. The space consumed by the VSWP file is more than compensated for by use of thin

provisioning.

Correct Answer: BSection: 5. Deploying and Managing Virtual Machines and vAppsExplanation

Explanation/Reference:The VSWP file only takes up space when the VM is powered on. When powered off, theVSWP file is automatically deleted. Although thin provisioning saves disk space, it may notsave disk space if the VM’s disks are 100 percent (or nearly 100 percent) full.

QUESTION 7You are deploying a VM from a Windows 2003 server template and want to have the newVM customized as part of the deployment process. Which of the following is necessary toallow for a customization of the new Windows server when deployed from this template?

A. Disks are dynamically shrunk when possible.B. Physical disk space is consumed as needed.C. Thin provisioning is transparent to the VM.D. Thin disks are dynamically defragmented as they grow.E. Thin disks allow for physical disk overcommitment.

298 Chapter 5 n Deploying and Managing Virtual Machines and vApps

Correct Answer: ADSection: 5. Deploying and Managing Virtual Machines and vAppsExplanation

Explanation/Reference:Thin provisioning supports dynamic growing of the underlying physical file ondemand but not dynamic shrinking. In this case, Storage VMotion could be leveraged toeffectively squeeze out unused space on a thin-provisioned virtual disk. VMware providesno fragmentation features in either thick- or thin-provisioned virtual disks.

QUESTION 14Assuming a Windows 2008 VM is at hardware version 7, which of the following cannotbe done?

A. Hot-add CPUsB. Hot-add RAMC. Dynamically shrink a virtual diskD. Dynamically grow a virtual diskE. Convert a thin-provisioned disk to a thick-provisioned disk


Explanation/Reference:Although there is now support for dynamically growing a virtual disk, there is still nosupport for dynamically shrinking a virtual disk on a running VM.

QUESTION 15You are trying to clone a VM and the clone operation is failing. Which of the following is a

possible reason for the failure?

A. You cannot clone Linux VMs.B. The VM has an open task in vCenter.C. The VM is at version 4 hardware.D. You have not installed the necessary Sysprep files onto the vCenter server.E. You need administrator privileges on the VM being cloned.


Explanation/Reference:Cloning will not work with a VM that has an existing snapshot. In general, snapshotsare best removed as soon as they are no longer required.

Answers to Review Questions 299

Correct Answer: BDSection: 5. Deploying and Managing Virtual Machines and vAppsExplanation

Explanation/Reference:VMware Tools provides additional and improved functionality in a VM. VMs can beinstalled or upgraded to virtual hardware version 7, however, even without VMware Tools.And although VMware Tools provide clock synchronization for the VM, you do not needVMware Tools to synchronize a VM’s clock—you can use an external time sync service likeActive Directory or the NTP.

QUESTION 19Which of the following statements about templates are not true?

A. With vSphere 4, you can now convert a running VM to a template.B. Templates are not recognized by standalone ESX/ESXi servers as they are a vCenter

feature.C. A template’s virtual disks can be in “thick” or “thin” (compact) format.D. A template can be recognized at the file level as its configuration filename ends in

.vmtx (instead of .vmx as for a VM).E. A template must have VMware Tools installed.

Correct Answer: AESection: 5. Deploying and Managing Virtual Machines and vAppsExplanation

Explanation/Reference:There is no support for (nor will the GUI interface even let you try to) convert a runningVM to a template. You can convert a VM to a template without installing VMware Tools intothe VM.

QUESTION 20What is the size of a VM’s virtual swap (VSWP) file?

A. 1 GBB. The RAM capacity of the VM as it was builtC. 10 GBD. The VM’s memory reservationE. The VM’s memory limitF. The VM’s memory limit minus the VM’s memory reservation

Correct Answer: FSection: 5. Deploying and Managing Virtual Machines and vAppsExplanation

Explanation/Reference:The VSWP file is set to the VM’s memory limit (which is by default set to the RAM capacity

of the VM as it was built) minus the VM’s memory reservation.

Exam F

QUESTION 1What is the correct order of operations when using host profiles?

A. Create reference profile, edit profile, attach profile, apply profile, check for complianceB. Check for compliance, create reference profile, attach profile, apply profileC. Install reference host, create reference profile, attach profile, check for compliance,

apply profileD. Import profile, create reference host, apply profile, attach profile, check for complianceE. Install reference host, create reference profile, attach profile, apply profile, check for

compliance

Correct Answer: CSection: 6. Managing ComplianceExplanation

Explanation/Reference:You must have an installed ESX server (the reference host) to start the process. From thisserver a reference profile is generated and attached to a vCenter inventory object (an ESXserver or a cluster). The ESX server(s) is scanned for compliance, and if desired, you canthen apply the profile to the ESX server(s).

QUESTION 2Which of the following is not a valid VUM setting?

A. Take a snapshot of a VM before patching and keep it indefinitelyB. Take a snapshot of a VM before patching and keep for a fixed period of timeC. Power off VMs on an ESX server if the ESX server fails to go into Maintenance modeD. Automatically rollback a snapshot after a fixed period of timeE. Suspend VMs on an ESX server if the ESX server fails to go into Maintenance mode

Correct Answer: DSection: 6. Managing ComplianceExplanation

Explanation/Reference:VUM can take snapshots before patching VMs and keep them indefinitely or for a fixedperiod of time. VUM can either power off or suspend VMs on ESX servers that fail to gointo Maintenance mode (typically because one or more VMs fail to properly move, usingVMotion, to another ESX server). Although you can manually roll back a VUM snapshot,VUM will not automatically do so.

QUESTION 3Host profiles require which of the following?

A. ESX 2.5 Update 2 or betterB. ESX/i 3.0 or betterC. ESX/i 3.5 Update 4 or betterD. ESX/i 4.0 or betterE. ESX/i 5.0 or better


Explanation/Reference:Host profiles were introduced with ESX 4.0 and are not backward compatible with priorversions of ESX. ESX 5.0 does not exist as of this writing.

QUESTION 4What are the two main types of VUM baselines you can create?

A. ESX/VMB. Windows/LinuxC. Update/UpgradeD. Patch/VMware ToolsE. Fixed/DynamicF. Full/Incremental

Correct Answer: ESection: 6. Managing ComplianceExplanation

Explanation/Reference:Fixed baselines contain patches selected from a list, are static in nature, and must bemanually kept up to date. Dynamic baselines are generated by VUM and automatically keptup to date as patches are released by vendors.

QUESTION 5Which of the following describes how VUM handles ESXi updates?

A. VUM does not update ESXi. You should manually save the ESXi settings, install froman updated ISO installer, and restore the saved settings.

B. ESXi updates are installed by merging patches from an update boot image with theESXi active boot image. The old pre-patch boot image becomes the standby bootimage.

C. VUM places the ESXi server in snapshot mode, applies the updates, and performs anauto-rollback if the update fails.

D. The ESXi server is removed from the DRS/HA cluster during patching and readdedonly if the patch was successfully applied.

E. VUM mounts the ESXi system disk as an image file, applies the patch to the mountedimage file, tests the patch, and reboots the ESXi server only if the patch is successful.

Correct Answer: BSection: 6. Managing ComplianceExplanation

Explanation/Reference:ESXi servers maintain an active (for the current boot) and standby (for rollback) systemboot image. VUM merges patches with (older) standby image, creating a new active bootimage. If anything goes wrong, this provides you the opportunity to boot the old standbyimage and have a working system.

QUESTION 6Which of the following statements about VUM baselines is true?

A. You should craft baselines carefully as you can only attach one to any given vCenterinventory object.

B. You can attach baselines to just about any inventory object in either the Hosts AndClusters or VMs And Templates views.

C. Baselines operate more efficiently when you combine VM and ESX patches in a singlebaseline.

D. Any given baseline can only be attached to a single vCenter inventory object.E. The default built-in baselines are not functional but only serve as templates for creating

your own baselines.


Explanation/Reference:Multiple baselines can be attached to any appropriate vCenter inventory object. Baselinescan be attached to most objects in the vCenter inventory, including individual VMs, individualESX hosts, folders, clusters, resource pools, data centers, and so forth. Individual baselinesconsist of VM or ESX patches but not both. Baselines can be attached to as many vCenterinventory objects as you need, and the default, built-in baselines are entirely functional.

QUESTION 7Which of the following functions cannot be performed by VUM? (Choose two.)

A. Check a VM’s hardware versionB. Install VMware ToolsC. Put an ESX server into Maintenance modeD. Apply new virtual switch definitionsE. Change ESX firewall port settings

Correct Answer: DESection: 6. Managing ComplianceExplanation

Explanation/Reference:VUM can check VMs to see if they are at the latest VM hardware version (7.0), caninstall the latest version of VMware Tools, and will put an ESX server into Maintenancemode (so as to evacuate all VMs off the ESX server) when patching an ESX server. The lasttwo answers are functions of host profiles, not VUM.

QUESTION 8You have decided to set up a separate download server for VUM to use when retrievingpatches. After installing the Download Service, you want to manually force the downloadingof all patches for ESX servers, Windows VMs, and Linux VMs. Which command willaccomplish this?

A. vmware-cmds –set-config –enable-downloads allB. vmware-cmds –set-config –enable-host 1 –enable-win 1 –enable-lin 1C. vmware-cmds –set-downloads allD. vmware-downloads –set allE. vmware-downloads –enable-downloads all


Explanation/Reference:Each separate set of patches to be downloaded is set with its own flag (a flag value of 1enables downloading whereas a flag value of 0 disables downloading).

QUESTION 9Which of the following are not required for proper VUM operation?

A. vCenterB. VUM databaseC. Download serverD. VUM server access to the InternetE. VUM plug-in


Explanation/Reference:The VUM server does not require access to the Internet, but the download server does.Even if the download server happens to be the same as the VUM server, it is still technicallythe download server, which needs Internet access (for accessing the patch download serversat VMware and Shavlik).

QUESTION 10ESX host profiles are generated from which of the following?

A. Any ESX host running ESX 3.5 Update 2 or laterB. A reference hostC. A templateD. The profile generator GUIE. An ESX server’s installation profile log


Explanation/Reference:Profiles are generated from an ESX 4.0 host, referred to as a “reference host.”

QUESTION 11Staging VUM patches for ESX servers requires which of the following?

A. ESX 2.5 Update 2 or betterB. ESX 3.0 or betterC. ESX 3.5 Update 4 or betterD. ESX 4.0 or betterE. ESX 5.0 or better


Explanation/Reference:Patch staging was introduced with ESX 4.0.

QUESTION 12Which databases are supported for a VUM server? (Choose three.)

A. MySQL

B. SQLC. SybaseD. OracleE. SQL Server Express

Correct Answer: BDESection: 6. Managing ComplianceExplanation

Explanation/Reference:VUM is only supported with Oracle, SQL, or SQL Server Express (with the correctand supported versions, of course). The VCP test notwithstanding, you should always checkthe manual to make sure you are looking at the list of currently supported databases.

QUESTION 13Which of the following does not describe a way in which VUM baselines interact withinventory objects?

A. Patches with an “unknown” status can be updated via remediation.B. Every time you view the compliance information for an object, the current compliance

status is updated.C. Linux VMs do not show compliance information for Windows VMs and vice versa.D. There is no compliance information for objects that do not have baselines attached.E. New patch compliance information is automatically shown as the new patches are

downloaded to the patch download server.F. Compliance information requires a minimum of read-only permissions on an object.

Correct Answer: ESection: 6. Managing ComplianceExplanation

Explanation/Reference:New compliance information is only guaranteed by performing a remediation. Themere act of downloading new patches does not update compliance report information,but would, in fact, generate more “unknown” hits in the compliance report.

QUESTION 14By default, which of the following URLs does VUM access for patch download information?(Choose two.)

A. https://update.microsoft.com/B. https://www.vmware.com/C. https:/www.kernel.org/D. https://xml.shavlik.com/E. https://patches.linux.org/

Correct Answer: BDSection: 6. Managing ComplianceExplanation

Explanation/Reference:By default, VUM obtains patches and patch information for ESX servers fromvmware.com and for Windows and Linux VMs from shavlik.com. Additional URLscan be configured for third-party patches.

QUESTION 15You have three vCenter servers operating in Linked Mode. How many VUM servers willyou have to install to support this configuration?

A. 1B. 2C. 3D. 4E. VUM is not supported with vCenter servers operating in Linked Mode in vSphere 4.0

Correct Answer: CSection: 6. Managing ComplianceExplanation

Explanation/Reference:When you have vCenter servers in Linked Mode, you must register separate instances ofVUM with each vCenter server.

QUESTION 16Which of the following describe features of staging patches for ESX/ESXi hosts?(Choose three.)

A. Patches must be staged for security reasons.B. Staging patches can speed up remediation.C. Staging patches can be done during normal ESX/ESXi operations.D. Staging patches reduces the amount of disk space required to store patches on the

download patch server.E. Maintenance mode downtime is reduced when staging patches.F. Staging patches eliminates the need for the download server to have an Internet

connection.

Correct Answer: BCESection: 6. Managing ComplianceExplanation

Explanation/Reference:Staging (copying patches from the download server to an ESX/ESXi server) duringnormal ESX/ESXi operations time speeds up remediation and reduces Maintenance modedowntime. There is no security requirement or benefit in staging patches. During the stagingprocess, disk storage for the patches is temporarily increased as the patch resides on both thedownload server and the ESX server being patched. As the stages patches come immediatelyfrom the download server, the download server still must be able to contact the patch serverson the Internet.

QUESTION 17Which of the following is not included in a host profile by default?

A. Firewall portsB. Date/timeC. Virtual switchesD. StorageE. The host’s FQDNF. User information

Correct Answer: E

Section: 6. Managing ComplianceExplanation

Explanation/Reference:Host profiles, by default, do not configure every single setting on an ESX server. Youwill still need to make sure you set (usually outside of a host profile) the server’s FQDN andIP information, for example.

QUESTION 18Which of the following is vSphere 4.0’s VUM not capable of doing? (Choose two.)

A. Patching ESXi hostsB. Patching ESX 2.5 hostsC. Patching ESX 3.5 hostsD. Patching ESX 4.0 hostsE. Upgrading an ESX 2.5 host to ESX 4.0F. Upgrading an ESX 3.5 host to ESX 4.0

Correct Answer: BESection: 6. Managing ComplianceExplanation

Explanation/Reference:VUM will do all of these except patching ESX versions earlier than 3.5 and so, byimplication, will not upgrade an ESX 2.5 host to ESX 4.0. If you manually upgrade anESX 2.5 host to ESX 3.5, then VUM can upgrade that host to ESX 4.0

QUESTION 19You want to install VUM in an environment with 10 ESX hosts and 100 virtual machines.Which of the following database options would not be supported in this environment?(Choose two.)

A. Oracle 9i (Release 2)B. Oracle 10g (Release 2)C. SQL Server 2005 (SP1)D. SQL Server 2005 ExpressE. SQL Server 2008

Correct Answer: ADSection: 6. Managing ComplianceExplanation

Explanation/Reference:Oracle 10 is the oldest release of Oracle supported for VUM in vSphere 4.0. SQLServer Express is supported only for installations with a maximum of 5 ESX servers and50 virtual machines.

QUESTION 20When remediating ESX hosts where you have multiple patches to install and there is a conflictof some sort, which of the following applies? (Choose two.)

A. If a patch in the baseline depends on another patch not in the baseline, you will beasked to install the other, required patch, first.

B. If two patches conflict, the oldest patch is installed first and the newer patch isinstalled last, guaranteeing the newer patch contents override the older patch contents.

C. If there are several versions of the same patch, VUM will install only the most recent

(i.e., latest) version.D. If a patch is marked as “obsolete,” the baseline will remove the patch.E. If multiple patches conflict but another patch resolves the conflict, VUM will install

the patches in the correct sequence to resolve the conflict.

Correct Answer: CESection: 6. Managing ComplianceExplanation

Explanation/Reference:If a patch depends on another patch, VUM will automatically install the other requiredpatch as well. If two patches conflict (and there is not another patch that resolves the conflict),neither of them is installed. VUM is intelligent enough to install only the most recent versionwhen multiple versions of the same patch are present.

Explanation/Reference:You can’t take a snapshot of a VM when it is powered on with a disk in independentmode. It is also not possible to take a snapshot of a VM while it is a template.

QUESTION 4Which of the following make compelling arguments in favor of using VMotion to move aVM? (Choose three.)

A. You want to meet service level agreements (SLAs).B. All of your ESX servers are severely underutilized.C. A SAN LUN is under heavy load.D. VMware has released an ESX patch.E. You want to update VMware Tools in your VMs.

Correct Answer: ABDSection: 7. Migrating, Backing Up, and Restoring Virtual MachinesExplanation

Explanation/Reference:VMotion, in general, is used to facilitate shifting loads and preparing for maintenanceactivities. Shifting loads can help with things like meeting SLAs and reducing powerconsumption with severely underutilized ESX servers (via DPM). Finally, installing a patchon an ESX server is an example of using VMotion for maintenance purposes.

QUESTION 5You would like to create a backup of the important configuration changes made on an ESXiserver. Which of the following would best help accomplish this?

A. Install a supported backup agent in a VM.B. Install a supported backup agent in the Service Console.C. Use the vMA appliance to back up the ESXi configuration.D. Use VMware Consolidated Backup.E. Use the VMware Data Recovery Manager plug-in.F. Create a vCenter template.

Correct Answer: CSection: 7. Migrating, Backing Up, and Restoring Virtual MachinesExplanation

Explanation/Reference:The vMA appliance vicfg-cfgbackup command can both create a backup of an ESXiserver’s configuration and restore the configuration. ESXi does not support installedbackup agents as it has no Service Console interface. VMware Consolidated Backup andData Recovery are used to back up and restore VMs, not ESX servers. Finally, templates areVM-only features and so would not work for backing up ESX/ESXi servers.

QUESTION 6Which of the following are allowed for suspended VMs? (Choose two.)

A. Using VMotion to move to another ESX serverB. Using cold migration to move to another ESX server in the same processor familyC. Using cold migration to move to another ESX server in a different processor familyD. Using Storage VMotion to move the VM’s filesE. Using cold migration to move the VM to a different vCenter datacenter

Correct Answer: BDSection: 7. Migrating, Backing Up, and Restoring Virtual MachinesExplanation

Explanation/Reference:Suspended VMs must resume on an ESX server in the same CPU compatibility group;therefore, you cannot use cold migration to move a suspended VM to an ESX server in anotherprocessor family. VMotion is not supported on suspended VMs. Storage VMotion is allowedon suspended VMs, and suspended VMs can be moved to different datacenters within vCenter.

QUESTION 7You have just purchased a new SAN to replace your old, aging SAN. Which of the followingwould be the most efficient way to move running VMs from the old SAN to the new SAN?

A. Storage VMotionB. Cold migrationC. VMotionD. SAN LUN replicationE. Manually copying the VM’s files to the new SAN LUN

Correct Answer: ASection: 7. Migrating, Backing Up, and Restoring Virtual MachinesExplanation

Explanation/Reference:Storage VMotion can move a running VM’s files from the old SAN to the new SANwith minimal (essentially zero) disruption to the VM. Cold migration requires the VM bepowered off, VMotion only moves the VM’s memory state (and so would not be helpful inmoving to a new SAN), SAN LUN replication would not update the VM’s vmdk and otherinfrastructure files correctly, and you would not be able to manually copy a running VM’sfiles due to vmdk file locking.

QUESTION 8When moving a VM or its files, you must decide whether to use VMotion, Storage VMotion,or cold migration. Which of the following considerations would inform your decision?(Choose two.)

A. VM downtimeB. Storage typeC. ESX server CPU speedsD. Crossing vCenter datacentersE. Thick- vs. thin-provisioned VM disks

Correct Answer: ADSection: 7. Migrating, Backing Up, and Restoring Virtual MachinesExplanation

Explanation/Reference:If you have no tolerance for downtime, cold migration is out of the question. In general,all of the migration technologies don’t care about the storage type but rather the storagelocation (i.e., shared vs. local). For VMotion, ESX server CPU speeds are not a concern aslong as the CPUs on the ESX servers are in the same processor compatibility group. None ofthe migration technologies listed are impacted by thin vs. thick disk provisioning. Fault tolerancerequires thick-provisioned disks but was not listed in the question.

QUESTION 9What is the maximum number of simultaneous VMotion migrations per host supported invCenter 4.0?

A. 1

B. 2C. 5D. 7E. 10

Correct Answer: BSection: 7. Migrating, Backing Up, and Restoring Virtual MachinesExplanation

Explanation/Reference:VMware supports up to two simultaneous VMotion migrations within a single vCenterinstance.

QUESTION 10Which of the following represent potential negative aspects of having a VM in snapshotmode? (Choose two.)

A. Snapshots can prevent VMotion migrations.B. Snapshots can prevent cold migrations.C. Snapshots can prevent VCB from backing up a VM.D. In time, the VM’s disk I/O performance can suffer.E. A VM with snapshots cannot be cloned.

Correct Answer: CDSection: 7. Migrating, Backing Up, and Restoring Virtual MachinesExplanation

Explanation/Reference:Snapshots are not compatible with VCB because VCB needs to take its own (exclusive)snapshot. Snapshots are not done for disk performance reasons—when the snapshots getlarge, I/O performance can suffer.

QUESTION 11Which of the following would not be helpful in backing up a VM?

A. Install a supported backup agent in the VM.B. Install a supported backup agent in the Service Console.C. Use the vMA appliance command line to back up the ESXi configuration.D. Use VMware Consolidated Backup.E. Use the VMware Data Recovery Manager plug-in.F. Create a vCenter template.


Explanation/Reference:There are several methods that are helpful in backing up a VM. Notably, with respectto backup functionality, the vMA appliance is generally only used for backing up an ESXiserver’s, not a VM’s, configuration.

QUESTION 12Which of the following is not an option when restoring a VM from a backup made with theVDR appliance?

A. Specifying the datastore to be used for restorationB. Opting not to restore the VM’s configuration (i.e., customizations stored in the VM’s

.vmx file)C. Choosing whether or not to have the VM’s NIC connectedD. Choosing whether or not to have the VM powered on after the restoreE. Scheduling the restore for a later time to minimize the impact on your virtual infrastructure

Correct Answer: ESection: 7. Migrating, Backing Up, and Restoring Virtual MachinesExplanation

Explanation/Reference:The VDR restore wizard has no provision for scheduling restoration.

QUESTION 13Which of the following is not possible when taking a snapshot of a virtual machine?

A. Rolling back to a previous memory stateB. Rolling back an individual file to a previous versionC. Rolling back a virtual disk to a previous stateD. Reverting a VM’s settings to a previous state


Explanation/Reference:Snapshots capture a VM’s disk state, settings, and (optionally) memory state. Thegranularity of the disk delta does not include the ability to roll back to previous versionsof files if the files are repeatedly changed.

QUESTION 14You have purchased the Advanced Edition vSphere license. Which of the followingmigration technologies can you use to move a VM or its files? (Choose two.)

A. VMotionB. Storage VMotionC. Cold migrationD. Template deploymentE. Storage Migration

Correct Answer: ACSection: 7. Migrating, Backing Up, and Restoring Virtual MachinesExplanation

Explanation/Reference:Advanced Edition licensing supports both VMotion and cold migration. StorageVMotion requires Enterprise Edition or Enterprise Plus Edition licensing. Template deploymentis not considered a method of moving a VM or its files, and VMware has no technologyknown as “Storage Migration.”

QUESTION 15You are having a problem getting a VM to successfully VMotion from one ESX server toanother. Which of the following is likely the reason for this?

A. You have not set up a dedicated Gigabit Ethernet VMotion network.B. Your ESX servers have been configured with the same IP address on the VMotion

network.C. DNS is not properly configured.D. The router connecting the two ESX servers on the VMotion network is down.E. You have defined the VMotion network on a standard virtual switch and VMotion

requires distributed virtual switches


Explanation/Reference:VMotion, although requiring a Gigabit Ethernet network, does not require a dedicatedGigabit Ethernet network. Each ESX server on the VMotion network must have a unique IPaddress, and they must be numbered on the same subnet. VMotion does not require DNS, butin general, your life will be a lot easier if you have DNS fully configured for your ESX/vCenterenvironment. As VMotion is currently supported only on a single network, a router connectingVMotion networks would be moot, and the VMotion virtual switch works equally wellwhether the switch is a standard or a distributed one.

QUESTION 16You would like to create a backup of the important configuration changes made on an ESXserver. Which of the following would best help accomplish this?

A. Install a supported backup agent in a VM.B. Install a supported backup agent in the Service Console.C. Use VMware Consolidated Backup.D. Use the VMware Data Recovery Manager plug-in.E. Create a vCenter template.


Explanation/Reference:As ESX servers still have a Service Console for management, a backup agent can beinstalled in the Service Console, facilitating backing up of either the entire Service Console(which includes all the ESX configuration files) or any set of important files you desire.VMware Consolidated Backup and Data Recovery are used to back up and restore VMs,not ESX servers. Finally, templates are VM-only features and so would not work for backingup ESX/ESXi servers.

QUESTION 17The VMware Data Recovery (VDR) appliance has which of the following requirements?(Choose two.)

A. The VDR is a stand-alone appliance and needs no other virtual infrastructure support.B. vCenter 4.0 and the vSphere ClientC. vCenter 2.0 or greater and the vSphere ClientD. ESX/i 4.0E. ESX/i 3.5 or greater

Correct Answer: BDSection: 7. Migrating, Backing Up, and Restoring Virtual MachinesExplanation

Explanation/Reference:The VDR appliance requires vCenter 4.0 and ESX/i 4.0 or later.

QUESTION 18You have just purchased a new ESX server to replace an old server that has been exhibitingintermittent system board failures. The new system is VMotion compatible with theold system, and you would like to move all the running VMs off the old system to the newsystem with a minimum of disruption. Which of the following would be the best way toaccomplish this?

A. Using Storage VMotionB. Using cold migrationC. Using VMotionD. Deploying a new VM from template and copying the old VM’s data file to the new VME. Backing up and restoring the VM using the VDR appliance


Explanation/Reference:VMotion can be performed while the VM is running with no disruption to runningapplications. Cold migration (although it would work in this case) requires the VM first bepowered off, generally a less than ideal solution. Storage VMotion, in this case, would notbe helpful as the VM’s files would not necessarily need to be moved. Deploying from templateand performing a backup/restore, although theoretically possible, would be much lessefficient than using VMotion.

QUESTION 19Which of the following is not a VMotion requirement for physical ESX hosts? (Choose three.)

A. You cannot be using the ESX server in the 60-day evaluation licensing mode.B. The storage used for the VM’s files must be presented to all ESX servers that might

want to VMotion.C. All virtual switches used by the VMs must be consistently named across all the

ESX servers.D. Each ESX server must have AMD-V or Intel VT instructions enabled.E. You must be running ESX 3.0 or later.

Correct Answer: ADESection: 7. Migrating, Backing Up, and Restoring Virtual MachinesExplanation

Explanation/Reference:The 60-day evaluation licenses are fully functional, including VMotion. All ESXservers must see the storage used by the VMs being VMotioned. The virtual switch namingrequirement only applies to virtual switches with outbound adapters (VMs with internalonlyswitches cannot be VMotioned). The AMD-V and Intel VT instructions are a requirementof Enhanced VMotion Compatibility (EVC) and not VMotion itself. Finally, VMotionprecedes ESX 3.x and is—for VMware—a mature technology.

QUESTION 20You are moving a VM’s files and ESX server simultaneously using cold migration. Whenyou work through the Cold Migration wizard, which of the following options are not presented?(Choose two.)

A. Selecting the destination ESX serverB. Selecting the destination datastoreC. Selecting the destination DRS/HA clusterD. Changing the VM’s disk format from thick to thinE. Changing the VM’s virtual switchF. Specifying the VM power-on after the cold migration

Correct Answer: EFSection: 7. Migrating, Backing Up, and Restoring Virtual MachinesExplanation

Explanation/Reference:When simultaneously changing ESX server and storage via cold migration, you canspecify (obviously) the destination ESX server and VM datastore. You can also specify adestination DRS/HA cluster and disk format change (from thin to thick or vice versa). Noform of migration allows you to change the VM’s virtual switch or have the VM power onafter the migration has completed.

Exam H

QUESTION 1Which resource pool setting would be most closely associated with a service levelagreement (SLA)?

A. ReservationB. LimitC. SharesD. Expandable

Correct Answer: ASection: 8. Managing and Creating VMware ClustersExplanation

Explanation/Reference:The reservation is a minimum guarantee and so most closely ties to SLAs. Since theLimit value is a best-effort delivery mechanism and shares only have meaning in the contextof a VM or resource pool contending for resources, they would not be the best mechanismfor providing an SLA guarantee. Making a resource pool expandable, although it allowsfor the “borrowing” of resources from a parent pool, is no guarantee the resources will beavailable at the time of borrowing.

QUESTION 2Which of the following VMware technologies would help you maximize VM uptime in theevent of a catastrophic ESX server hardware failure?

A. VMotionB. Distributed Resource Scheduler (DRS)C. VMware High Availability (HA)D. Storage VMotionE. Resource pools

Correct Answer: CSection: 8. Managing and Creating VMware ClustersExplanation

Explanation/Reference:VMotion, DRS, and Storage VMotion are all anticipatory technologies. You performthem ahead of an anticipated downtime/maintenance window. HA reacts to ESX serverfailures, rebooting VMs quickly. Resource pools are used to assign resources to VMs in afair manner and are not directly involved with hardware failures.

QUESTION 3Distributed Power Management (DPM), before making a decision to take a host out ofStandby mode, averages cluster resource use over what period of time?

A. 5 minutesB. 20 minutesC. 30 minutesD. 1 hourE. You have to configure the parameter value first.


Explanation/Reference:The /etc/HA_HOSTS carries the IP addresses of all ESX HA network interfaces in theHA cluster and is used by the HA hosts to implement redundant heartbeat. The presenceof this file guarantees heartbeat will work even in the event of DNS failure.

QUESTION 4Which of the following does not apply to HA VM monitoring?

A. VMware tools are not required in the VM for HA to monitor individual VMs.B. You can configure the failure interval: how long a VM must be nonresponsive before

being rebooted.C. You can configure the number of times per hour HA will attempt to reset a nonresponsive

VM.D. VMs can have their restart priority (high, medium, low, disabled) individually set.


Explanation/Reference:VMware tools are required in a VM for HA to monitor them individually.

QUESTION 5What is the default resource pool reservation for memory?

A. 1000MBB. 500MBC. No reservationD. The maximum allowed on that host

Correct Answer: CSection: 8. Managing and Creating VMware ClustersExplanation

Explanation/Reference:Once a resource pool has been created, it will not have any reservations or limits formemory or CPU. It is up to the administrator to set those values as necessary.

QUESTION 6What is the maximum number of failover hosts allowed in an HA cluster?

A. 1B. 4C. 5D. 7E. 8

Correct Answer: BSection: 8. Managing and Creating VMware ClustersExplanation

Explanation/Reference:HA clusters allow for a maximum of four simultaneous host failures. There must be amaximum of five primary hosts in an HA cluster, one of which must always be running.

QUESTION 7Which of the following protocols are used by DPM to manage the cycling of hosts into andout of Standby mode?

A. PowerSaveB. IPMIC. WOLD. DiPME. iLOF. ESave

Correct Answer: BCESection: 8. Managing and Creating VMware ClustersExplanation

Explanation/Reference:DPM can utilize IPMI (Intelligent Platform Management Interface), WOL(Wake-on-LAN), or iLO (Integrated Lights-Out) technologies.

QUESTION 8What are the three automation levels possible when configuring a DRS cluster?

A. Fully Automated


B. Semi-AutomaticC. ManualD. Partially Automated

Correct Answer: ACDSection: 8. Managing and Creating VMware ClustersExplanation

Explanation/Reference:A DRS cluster can provide Manual mode for administrators who want completecontrol of where a VM is powered on and whether a VM is VMotioned to another host.Partially Automated allows the VM to be powered on a host of the cluster’s choosing, butwill not VMotion the VM for load balancing. Fully Automated will do both actions withoutinput from the administrator.

QUESTION 9Which of the following VMware technologies is disruptive in the operation of a virtualmachine?

A. HAB. DRSC. VMotionD. Fault ToleranceE. Storage VMotion


Explanation/Reference:Only HA is disruptive, reacting to either a failed ESX server or a failed VM, rebootingthe VM as quickly as possible after detecting the failure. DRS, VMotion, FT, and StorageVMotion all operate without disrupting the real-time operations of virtual machines.

QUESTION 10What is a cluster’s target utilization used by DPM?

A. 50 percentB. 63 percentC. 67 percentD. 75 percent

Correct Answer: BSection: 8. Managing and Creating VMware ClustersExplanation

Explanation/Reference:The average overall load on a cluster is targeted at 63 percent by the Distributed PowerManagement engine. If the cluster load falls significantly below this value, hosts may be putinto Standby mode; if the load rises significantly above this value, hosts may be pulled backout of Standby mode.

QUESTION 11VMware Fault Tolerance (FT) currently has several restrictions. Which of the following isnot a restriction of FT?

A. The VM must not be running Linux.B. The VM must not be in an MSCS cluster.C. The VM must not be using paravirtualization.D. You cannot use thin-provisioned disks on an FT VM.


Explanation/Reference:FT works with any supported guest OS.

QUESTION 12Distributed Power Management (DPM), before making a decision to put a host intoStandby mode, averages cluster resource use over what period of time?

A. 5 minutesB. 40 minutesC. 30 minutesD. 1 hourE. You have to configure the time first.

Correct Answer: BSection: 8. Managing and Creating VMware Clusters

Explanation

Explanation/Reference:DPM takes a rolling 40-minute resource usage average before making any decisions. Theidea is to not move VMs and put hosts into Standby mode needlessly as there is a significantamount of overhead and time involved in going into and back out of Standby mode. Contrastthis with the 5-minute average interval used to pull an ESX server back out of Standby mode.

Exam I

QUESTION 1Which of the following is a network metric?

A. READ/sB. LQLENC. %RUND. %DRPTX

Correct Answer: DSection: 9. Alarm ManagementExplanation

Explanation/Reference:READ/s and LQLEN are disk metrics measuring the number of read requests (host orVM) per second and the LUN queue depth respectively. %RUN is a CPU metric measuringCPU scheduling as a percentage. %DRPTX is the percentage of transmitted packets dropped.

QUESTION 2Which of the following is not a reason to create a custom alarm in vCenter? (Choose two.)

A. You want to define a specific SNMP trap receiver.B. You want to limit the VMs an alarm applies to.C. You need DRS/HA cluster-specific alarms.D. You need a VM memory alarm to apply to your entire inventory.E. You want to specify an alarm icon color change.

Correct Answer: ADSection: 9. Alarm ManagementExplanation

Explanation/Reference:You can define a trap receiver on any of the built-in alarms by simply filling out thetrap receiver information in vCenter, and so no custom alarm is needed there. The defaultbuilt-in alarms apply to the entire inventory, so a custom alarm would not be needed in thatcase either.

QUESTION 3Which of the following is a default vCenter connectivity alarm?

A. Host Processor StatusB. Virtual Machine ErrorC. Cannot Connect To StorageD. Host Storage StatusE. Migration Error

Correct Answer: CSection: 9. Alarm ManagementExplanation

Explanation/Reference:The default vCenter connectivity alarms are Cannot Connect To Network, CannotConnect To Storage, Host Connection And Power State and Host Connection Failure.

QUESTION 4

Which of the following is not a disk performance metric?

A. READ/sB. LUN_LATENCY_QUEUE_DEPTHC. AQLEND. LQLEN

Correct Answer: BSection: 9. Alarm ManagementExplanation

Explanation/Reference:READ/s is the number of read requests (host or VM) per second, AQLEN is the storageadapter queue depth, and LQLEN is the LUN queue depth. Option B is entirely made up.

QUESTION 5An ESX server suffers a host failure. You have configured the vCenter alarm Host ConnectionAnd Power State to generate an SNMP trap. You are not receiving any SNMP trapsindicating the ESX host failure. What is the likely cause of this?

A. You have not defined an SNMP trap receiver in the Administration ? vCenter ServerSettings ? SNMP properties.

B. You have not defined an SNMP trap receiver in the Administration ? Custom Attributesproperties.

C. You have not enabled the SNMP agent in the Service Console.D. You have not installed the SNMP vCenter plug-in.E. You have suffered a failure in the Service Console virtual switch.

Correct Answer: ASection: 9. Alarm ManagementExplanation

Explanation/Reference:In addition to specifying the SNMP alarm action in the Action tab of the alarm’sproperties, you need to specify the SNMP trap receiver’s IP address in the Administration? vCenter Server Settings properties.

QUESTION 6When you attempt to create an advanced performance chart (see the following graphic), youreceive an error. What is happening to generate the error?

A. You can only graph two discrete data points at a time with Advanced graphs.B. You can only graph one rollup type at a time with Advanced graphs.C. You can only graph two discrete units at a time with Advanced graphs.D. In fact, you will not receive an error; the graph will be produced as expected.


Explanation/Reference:Advanced graphs only support two discrete units at a time. So, although you cangraph more than two data points, they must consist of, at most, two units (percent, millisecond,MHz, etc.).

QUESTION 7

A custom alarm you have created repeatedly triggers on the same event every minute. As thetrigger sends out an email, you would like to avoid having to deal with the extra redundantemail messages every minute. What could you do to help eliminate these redundant emailmessages? (Choose two.)

A. Uncheck the Enable This Alarm option in the alarm’s General preferences tab.B. Increase the trigger condition length in the alarm’s Triggers preferences tab.C. Increase the Repeat Triggered Alarm Every… Minutes value in the alarm’s Reporting

preferences tab.D. Increase the Repeat Triggered Alarm When Condition Exceeds This Range in the

alarm’s Reporting preferences tab.E. Change Repeat to Once in the color change box of the alarm’s Actions preferences tab.

Correct Answer: CDSection: 9. Alarm ManagementExplanation

Explanation/Reference:Alarms have two general mechanisms for preventing repeated triggering and they areboth found in the alarm’s Reporting preferences tab. For numeric alarms, option D willkeep an alarm from retriggering until the initial trigger value goes up by this amount. Also,an alarm will not retrigger within the time interval specified in the Repeat Triggered AlarmEvery box (option C).

QUESTION 8You have several VMs running on an ESX server, none of which are remotely close to 100percent CPU usage. The ESX server itself is also not remotely close to 100 percent CPUusage. Despite this, you notice all of the VMs are accumulating a lot of CPU Ready time.What might be the underlying cause of this?

A. The VMs are I/O bound.B. The VMs are network bound.C. You have masked out NX/XD for the VMs.D. The VMs have multiple virtual CPUs but are only actively using a small fraction of a

single CPU’s cycles.E. Several VMotion migrations are occurring.

Correct Answer: DSection: 9. Alarm ManagementExplanation

Explanation/Reference:When you build a VM with multiple vCPUs, all of the vCPUs must be simultaneouslyscheduled onto physical CPUs regardless of whether the VM is actively using its allottedvCPUs. In this case, you would notice a lower than expected physical CPU utilization onthe ESX server due to the multiple idle vCPUs. VMs that might otherwise be able to runwill be accumulating Ready time, waiting on the physical CPUs to become available.

QUESTION 9Looking at CPU Usage for an ESX host, you notice the physical processors are beingoverutilized. Looking at CPU Usage for all the VMs running on the same ESX server, younotice none of the VMs are overutilized. Several users are complaining, however, that theirVMs seem sluggish. What could be the underlying cause?

A. You have not enabled hyperthreading on your ESX server.B. You have enabled hyperthreading on your ESX server.

C. The VMs are filling the physical NICs with network trafficD. The VMs have CPU reservations that are set too low.E. You have VMs unnecessarily configured as multiprocessor servers.


Explanation/Reference:Remember, high virtual network activity can generate a significant CPU load. Sendingand receiving network packets, from a CPU standpoint, is not free.

QUESTION 10You receive a Cannot Connect To Storage alarm in vCenter. Which of the following mayindicate the reason for this alarm? (Choose two.)

A. Lost network connectivityB. Incorrect CCAgentC. Lost storage connectivityD. Host connection lost

Correct Answer: ACSection: 9. Alarm ManagementExplanation

Explanation/Reference:Losing storage connectivity may be caused (in addition to the more obvious option C)by losing network connectivity if the storage is IP based, such as NFS or iSCSI.

QUESTION 11The default Host CPU Usage alarm is set to trigger an alert at:

A. 75 percent CPU for a period of 5 minutesB. 75 percent CPU for a period of 10 minutesC. 90 percent CPU for a period of 5 minutesD. 90 percent CPU for a period of 10 minutesE. 50 percent CPU for a period of 5 minutes


Explanation/Reference:The 75 percent threshold is for a warning and the 90 percent threshold is the level for analert. Host CPU alarm defaults are all based on 5-minute duration.

Exam J

QUESTION 1You are planning on using the built-in vCenter alarm, which warns of lost storage connectionproblems. After you lose connectivity to a particular iSCSI array, you notice the alarmnever sent you any indication. Why?

A. This built-in alarm is not enabled by default.B. There is no default action specified for this alarm.C. The default action (send email) requires you set up vCenter Mail settings.D. The default action (send a notification trap) requires you specify at least one SNMP

trap receiver.

Correct Answer: DSection: 10. Performing Basic TroubleshootingExplanation

Explanation/Reference:The built-in alarm (“Cannot connect to storage”) is enabled and wants to send an SNMPtrap by default. However, vCenter is not automatically configured with an SNMP trap sink,which you will need to configure for this alarm to be effective.

QUESTION 2Which of the following is not monitored by the new ESX hardware health function?

A. CPUB. FanC. BatteryD. MonitorE. Temperature


Explanation/Reference:The new hardware health monitor monitors the following: processor (CPU), memory,fan, voltage, temperature, power, network, storage, cable/interconnect, software component,watchdog, and an “other” category. No monitor monitoring is done.

QUESTION 3Where would you verify/change the network settings for the management network on anESXi server?

A. The Service Console port group on vSwitch0B. The Management Network port group on vSwitch0C. The VM Network port group on vSwitch0D. The VMkernel port group on vSwitch0

Correct Answer: BSection: 10. Performing Basic TroubleshootingExplanation

Explanation/Reference:ESXi has no Service Console and the management network is, therefore, on a VMkernelport group labeled Management Network on the initial (vSwitch0) vSwitch. Only ESX servers

have a Service Console port group proper.

QUESTION 4You have put an ESX server into Maintenance mode so that you can perform periodic hardwaremaintenance. Although the ESX server is in a DRS cluster, you notice, after severalhours, the ESX server still has not completed the transition into Maintenance mode. Whatshould you do? (Choose two.)

A. Wait longer; entering Maintenance mode frequently takes up to 24 hours to complete.B. Check to see if DRS is in fully automatic mode.C. DRS must be in semiautomatic mode.D. Some of the VMs may not satisfy VMotion requirements.E. You need to manually shut down or VMotion VMs when you put an ESX server into

Maintenance mode.

Correct Answer: BDSection: 10. Performing Basic TroubleshootingExplanation

Explanation/Reference:For an ESX server to complete the transition into Maintenance mode, all the VMsrunning on it must be shut down or VMotioned to another ESX host. If you are running aDRS cluster, the easiest way to accomplish this is to have DRS running in fully automaticmode and ensure all the VMs meet VMotion compatibility requirements. Failing that, youwill have to manually shut down VMs or ensure they meet VMotion requirements.

QUESTION 5You are experiencing a problem with a VMkernel port group on a dvSwitch. You think theproblem may be that it has been set with an incorrect IP address. You would like to examineand correct the IP address on this port group (assuming that is the problem). Using thevSphere Client, logged into vCenter, how would you do this?

A. Click Home ? Inventory ? Networking, select the dvSwitch, and click Edit Settings.B. Click Home ? Inventory ? Hosts And Clusters, select an ESX server, click the Configuration

tab, click Networking, click Distributed Virtual Switch, select the dvSwitch, clickManage Virtual Adapters, select the port group, and examine or edit as appropriate.

C. Click Home ? Inventory ? Networking, select the dvSwitch, right-click the portgroup, and select Edit Settings.

D. Click Home ? Networking, select the correct virtual switch, right-click the port group,and select Edit Settings.


Explanation/Reference:Editing distributed switch port-specific IP address settings is done via the Hosts AndClusters view, not the Networking view.

QUESTION 6What is the recommended maximum number of VMs to have in FT mode on an ESX server?

A. 1–2B. 2–4C. 4–8D. 8–16

Correct Answer: CSection: 10. Performing Basic TroubleshootingExplanation

Explanation/Reference:The current, initial release of Fault Tolerance recommends you run no more than 4–8 VMswith FT on a single ESX server. If the VMs are busy, you would want to err on the low side.

QUESTION 7When you are looking at the Maps tab (view) of an ESX server in vCenter’s Hosts AndClusters view, why would an ESX server in the map have a red “x” superimposed over it?

A. The ESX server has crashed.B. The ESX server does not meet VMotion requirements.C. The ESX server is overcommitted.D. The ESX server is rebooting.


Explanation/Reference:Although the red “x” will tell you an ESX server does not meet VMotion compatibilityrequirements, it will be up to you to investigate the exact cause and rectify it before attemptingto use that particular ESX server in a VMotion action.

QUESTION 8When you generate a log bundle using the vm-support command, what is the format of thegenerated file?

A. TARB. ZIPC. TGZD. CAB


Explanation/Reference:The vm-support command generates a compressed (gz) tar archive (t) file, hence the.tgz extension.

QUESTION 9You have a DRS cluster with three ESX servers. In the vSphere Client GUI you are lookingat the resource distribution chart in the cluster’s Summary tab. All of the ESX servershave multiple VMs running on them, all of which satisfy VMotion requirements. On twoof the ESX servers, the VM’s CPU utilization per host bars are all green, whereas on thethird ESX server all of the VMs CPU utilization bars are yellow or red. What can you doto fix this not only immediately but into the future as well?

A. You are running too many VMs; power some of them off.B. Put DRS into fully automatic mode.C. Apply DRS VMotion recommendations of three stars or more.D. Change the CPU reservations of the VMs that are showing red bars.


Explanation/Reference:That you have two ESX servers with green bars indicates they are probably not runningover capacity. If you put the DRS cluster into fully automatic mode, DRS will apply VMotionrecommendations, automatically balancing the load across all three servers (not just two asappears to be the case currently).

QUESTION 10Which command could you use in the Service Console to verify the proper IP address informationhas been set for correct Service Console networking?

A. ifconfigB. ipconfigC. netconfigD. testnetE. vicfg-nics

Correct Answer: ASection: 10. Performing Basic TroubleshootingExplanation

Explanation/Reference:ipconfig is a Linux/Service Console command that returns many of the IP configurationparameters for an interface, including IP address, netmask, and broadcast address.ipconfig tells you the current configuration parameters in the system initialization filesor what may have been previously manually set.

QUESTION 11How would you verify a VM’s IP address, subnet mask, default gateway, and DNS servers?

A. Select the VM in the vSphere Client GUI, click Edit Settings, select the Networkadapter, and view all the settings.

B. Select the VM in the vSphere Client GUI, and click the Summary tab.C. In the Windows VM, open a DOS command window and enter the ipconfig /all

command.D. Select the VM in the vSphere Client GUI, click Edit Settings, click the Options tab, and

select the Network options.


Explanation/Reference:The vSphere Client GUI has no place where you can view all of the VM’s network settings.The VM’s Summary tab shows the VM’s IP address, but for the other settings you will have togo inside the VM itself (as you would on a physical server) and use a utility of your choosing inthe guest OS.

QUESTION 12Which of the following is not a VMotion compatibility requirement?

A. VMs cannot be connected to a virtual device that is mapped to a physical device onthe host.

B. ESX host CPUs must be in the same processor family.C. VMs must not be connected to standard vSwitches.D. VMs must not be connected to internal vSwitches.E. VMs must not be using CPU affinity.


Explanation/Reference:There is no restriction as to standard versus distributed virtual switches.

QUESTION 13If you are unsure a physical network adapter’s (speed, duplex) settings are correct or ifyou just need to verify other physical network adapter settings (MAC address, observed IPaddress ranges, wake on LAN support), which vSphere Client GUI form would you use?

A. Click Home ? Inventory ? Networking ? Virtual Switches.B. Click Home ? Inventory ? Networking and select the appropriate dvSwitch uplink

port group.C. Click Home ? Inventory ? Hosts and Clusters, select an ESX server, click the Configuration

tab, click Networking, and click Properties next to the vSwitch you need to query.D. Click Home ? Inventory ? Networking, select a dvSwitch, and click the Ports tab.


Explanation/Reference:Uplink/physical NIC adapter’s properties are viewed via the Hosts And Clusters view.The NIC’s speed and duplex can be set here while the other parameters can be examined.

QUESTION 14Which of the following commands would be used to generate a log bundle suitable to diagnosinga problem on your own or sending to VMware technical support for assistance?

A. vm-supportB. vicfg-exportlogsC. vm-exportlogsD. esxcfg-support


Explanation/Reference:The vm-support command is used to generate a log bundle (compressed tar) file. Noneof the other commands are real.

QUESTION 15You have decided to install ESX onto a SAN LUN (that is, boot from SAN). Which of thefollowing would be best practice?

A. Present the boot LUN to all ESX servers.B. Present the boot LUN to the booting ESX server only.

C. Present the boot LUN to all ESX servers in the DRS/HA cluster.D. Boot from SAN is not supported in vSphere 4.


Explanation/Reference:For security and performance reasons, you should present the boot LUN only to the ESXserver booting from that LUN.

QUESTION 16A virtual machine is unable to communicate on the physical production network. Inexamining the virtual machine’s settings, you notice it has a virtual NIC, which seems tobe connected to the correct port group. Other VMs on the same ESX server are connectingto the production network just fine. What might be the cause of the problem?

A. You need to reboot the VM.B. You need to restart the network agents on the ESX server.C. The Connect At Power On check box is not selected in the VM’s Network adapter

hardware Properties dialog box.D. The Connected check box is not selected in the VM’s Network adapter hardware

Properties dialog box.E. The virtual switch name is “production” on this ESX server, but “Production” on

another ESX server.


Explanation/Reference:Make sure the VM’s network adapter is connected. Rebooting the VM won’t help in thiscase, nor will restarting networking on the ESX server. The Connect At Power On check boxonly helps after a reboot (which should be unnecessary in this case). Although virtual switchnames need to be consistently labeled across ESX servers for VMotion compatibility purposes,that is not the problem here.

QUESTION 17What would you examine as an indicator of an ESX server’s being unable to keep up withVM disk requests?

A. The device queue depthB. BallooningC. %ReadyD. Disk overcommitment


Explanation/Reference:Large device queue depths indicate disk requests coming into the ESX server (and byimplication the storage devices) faster than they are being satisfied, sort of like a long lineat the bank. Longer queue depths/longer lines means longer wait times for the applicationsneeding the data. Ballooning is a memory resource measurement, %Ready is a CPU resourcemeasurement, and disk overcommitment helps you analyze the overuse of thin-provisioned

virtual disks.

QUESTION 18Having ESX servers properly configured for DNS usage is most important with whichfeature?

A. VMotionB. DRSC. HAD. Storage VMotion


Explanation/Reference:Although HA can be made to work without the benefit of DNS, it is more work andhaving a properly functioning DNS is something you should be doing anyway. None ofthe other features listed rely on DNS the way HA does.

QUESTION 19One of your ESX servers has lost connectivity with vCenter. You have decided to look at thelog files on the ESX server to see if you can get an indication of the source of the problem.Which of the following log files would be most likely to help you troubleshoot this problem?

A. /var/log/messagesB. /var/log/VMkernelC. /var/log/vmkwarningD. /var/log/service-consoleE. /var/log/errors


Explanation/Reference:The management network on an ESX server is handled via a Service Console networkconnection. Therefore, the file you would check first would be /var/log/messages, thegeneral Service Console error log.

QUESTION 20A VM has been disconnected from the proper vSwitch port group and so has lost its networkconnectivity. You correct the problem by reconnecting the VM to the correct vSwitch portgroup, but the VM is still unable to access the network. Other VMs on the same vSwitchport group on the same ESX server are successfully connecting to the network. What mightyou do to correct this problem? (Choose two.)

A. If the VM is using a DHCP-supplied IP address, use the command ipconfig /releasefollowed by ipconfig /renew.

B. If the VM is using a static IP address, double-check to make sure the address is for thecorrect subnet.

C. Check the vSwitch to make sure it is using the correct physical uplink NICs.D. Restart the network agents on the ESX host.E. Reboot the ESX host.

Correct Answer: AB

Section: 10. Performing Basic TroubleshootingExplanation

Explanation/Reference:Anytime you have to reconnect a VM to a network, ask yourself, “How would thisbehave if it was a physical server on a physical network?” You may need to reassign or assigna new IP address to the VM’s network interface. In this particular scenario, the problem islikely not with the underlying physical NICs or the ESX network agents because other VMson the same ESX server are working well.
