QUESTION 1DRS rules can help satisfy availability concerns within a cluster; however, if used extensively, they may cause aperformance issue with vCenter.

A. TrueB. False

Correct Answer: ASection: (none)Explanation

Explanation/Reference:Explanation:DRS rules can be extremely useful for a number of reasons, such as redundancy, network bandwidth, andperformance management. However, if they are used extensively, functionality such as DPM may become lesseffective (that is, hosts will not be able to power off due to rules and will use more power than required).

Chapter 4, Management/Platform Design

QUESTION 2You are reviewing a VMware vSphere 5 cluster design. The system is designed to run DPM in fully automatedmode. DPM in fully automated mode ____ evacuate all templates when placed into standby mode.

A. willB. will not

Correct Answer: BSection: (none)Explanation

Explanation/Reference:Explanation:DPM will not move powered-off virtual machines or templates. A real-life workaround is to turn off fullyautomated DRS for these machines on a case-by-case basis and register them to a specific host in the clusterfor deployment usage.

QUESTION 3Has the configurable option "Failure Detection Time" in VMware HA has been removed in vSphere 5?

A. No. It is an advanced setting.B. Yes. It is no longer needed due to additional storage checks in the VMware HA isolation response process.


Explanation/Reference:Explanation:vSphere 5 will use datastore heartbeats in a disaster. Thus, this setting is no longer available or supported inVMware vSphere 5.

Chapter 4, The Importance of vMotion, VMware HA, and Fault Tolerance

QUESTION 4

You are designing a VMware HA cluster. In vSphere 5, VMware HA will take cluster resource fragmentation intoaccount and ask DRS to defragment the cluster, if required.

A. TrueB. False


Explanation/Reference:Explanation:In VMware vSphere 5, this HA functionality is fully automated and does not use any specific custom settingswith regard to reservations or slot sizes. VMware HA functions can request DRS to migrate workloads acrossthe system in multiple rounds of vMotion tasks. This can help defragment the cluster and restart VMs that havebeen affected by a failed host. Chapter 4, The Importance of vMotion, VMware HA, and Fault Tolerance

QUESTION 5A guest VM should be sized using ____________. (Choose two)


A. minimum applications specificationsB. initial workloadC. anticipated workloads

Correct Answer: ACSection: (none)Explanation

Explanation/Reference:Explanation:Allocated resources are shown in the guest operating system and are not guaranteed. The amount depends onthe unreserved resources available at the time. Assuming no functionality issues, you can configure aproduction application to be guaranteed its projected workload, and the system should deliver. Without areservation, there is potential for a performance impact if there is contention.

QUESTION 6You are a VMware consultant working at a small managed services company. The company has won acontract with a large company, Company A, to host its test and dev. platform, with the chance on annual reviewto host the production platform.

Although you have been engaged early in the project due to business requirements, the budget for the projecthas already been combined with that for another DR project for another company, Company B.

The thought process for this decision is that, if needed, the test systems from Company A have a lowerrequirement in the unlikely event of Company B having a DR event.

All the items have been bought and are to be delivered. Your role is to take the equipment provided and

construct, develop, and implement a scalable working vSphere platform.

The following requirements are stated:

Company A's test machines must be provided with sufficient resources for BAU.Company B's systems must be made available with minimum impact to Company A.The RTO for Company A is seven days, with an RPO of one month.Company B's RTO is 1 hour, and its RPO is 15 minutes.

Using a shared infrastructure in this way is a risk to the project.

A. TrueB. False


Explanation/Reference:Explanation:The technical design process enables the platform designer to work in a methodical way and with others withsimilar objectives. A risk is an object that could prevent the delivery of the project requirements.

QUESTION 7You are a VMware consultant working at a small managed services company. The company has won acontract with a large company, Company A, to host its test and dev. platform, with the chance on annual reviewto host the production platform.

Although you have been engaged early in the project due to business requirements, the budget for the projecthas already been combined with that for another DR project for another company, Company B.

The thought process for this decision is that, if needed, the test systems from Company A have a lowerrequirement in the unlikely event of Company B having a DR event.

All the items have been bought and are to be delivered. Your role is to take the equipment provided andconstruct, develop, and implement a scalable working vSphere platform.

The following requirements are stated:

Company A's test machines must be provided with sufficient resources for BAU.Company B's systems must be made available with minimum impact to Company A.The RTO for Company A is seven days, with an RPO of one month.Company B's RTO is 1 hour, and its RPO is 15 minutes.

The use of a shared infrastructure used in this way is a constraint to the project.

A. TrueB. False


Explanation/Reference:Explanation:An item from the current state analysis that would restrict or change a design choice is potentially a constraint.These factors can limit the design and in some cases prevent the realization of the project vision.


QUESTION 8A current state analysis is a project phase that is carried out to ensure that an architect understands thecomplete environment at the beginning of a project.

A. TrueB. False


Explanation/Reference:Explanation:A current state analysis gives an architect a way to examine the road ahead. Any oversights at this stage couldhave major implications for the project later on. By ensuring that the current state analysis is completedthoroughly, you can prevent many potential problems.

QUESTION 9The difference between the beginning of a project and the vision is also known as the ____________.

A. current state analysisB. gap state analysisC. upstream relationshipD. downstream relationship


Explanation/Reference:Explanation:By reviewing the current configuration of a system and mapping the final status of components as described inthe vision, the business identifies the gap between the two. A gap state analysis is a review of the items ortasks that are required to progress between the stages. Such an analysis is useful in creating milestone plans,implementation orders, and so on.

QUESTION 10The analysis of the difference between the beginning of a project and the vision is also known as the currentstate analysis.

A. TrueB. False



QUESTION 11A gap state analysis is a review of the items or tasks required to progress from the current environment to thevision.

A. TrueB. False



QUESTION 12A component relationship diagram can be used to establish impact analysis.

A. TrueB. False


Explanation/Reference:Explanation:In an upstream relationship, a logical object or component has a dependency on other items in the solution. Forexample, a service running on an application server requires an Active Directory user account to beauthenticated. The application service must be started after the Active Directory service. Therefore, theapplication server has an upstream relationship with the Active Directory service.

In a downstream relationship, a logical object or component does not have a dependency on other items in thesolution. For example, say that a multisite web server crashes. The web tier hosting multiple websites willcrash; however, the downstream objects such as the database server will continue to function. Backendprocesses that are dependent on the downstream objects from the web servers can continue to function.

QUESTION 13A logical diagram may contain ____________. (Choose two)

A. relationship informationB. Data flow informationC. IP addressesD. vendor information

Correct Answer: ABSection: (none)Explanation

Explanation/Reference:Explanation:A logical diagram can be used to show service components and how they relate to each other. A logicaldiagram is a high-level diagram that is independent of the hardware used for the solution.

QUESTION 14A project vision _______________.

A. is the required endpoint of a project--the purpose for completing the processB. can be achieved after several iterations of a project life cycleC. both of these are correct

Correct Answer: CSection: (none)Explanation

Explanation/Reference:Explanation:The project vision indicates the final state the platform should be in. It is the business-led objective, whichprovides value and incorporates the infrastructure qualities.

QUESTION 15Vendor-best practices can be used to guide ______________.

A. configuration and design choices in the absence of project requirementsB. configuration and design choices in addition to project requirementsC. both these answers are correct


Explanation/Reference:Explanation:A best practice is normally based on experience with a successful implementation. By using theseconfigurations, known issues could possibly be avoided. Best practices should not replace project requirementsbut can be used as a starting point, as long as the project requirements are satisfied.

QUESTION 16You are planning a vSphere 4.1 to 5.0 upgrade. The production datastores are 6 TB. Each datastore consist ofthee extents of 2 TB and is currently 65% full. The operations team would like to keep the system as close tothe current configuration as possible. The upgrade process also requires as little service impact as possible. Inaddition, you wish to use storage I/O control as soon as possible, due to a mission-critical business applicationrequirement. Which of the following would be the correct approach?

A. Create a new VMFS 5 datastore of 6 TBEnable storage I/O controlMigrate the VMs using storage vMotionConfigure storage I/O shares as required

B. Upgrade the VMFS 3 datastoreEnable storage I/O controlConfigure storage I/O shares as required


Explanation/Reference:Explanation:When a datastore with VMFS v3 is upgraded with extents to VMFS v5, the logical attributes and extents are notchanged. Storage I/O control cannot be used with datastores composed of extents.

QUESTION 17A logical diagram does not include ____________.

A. high-level components and how they relate to the solutionB. detailed information regarding the components, such as model of systems, IP addresses, and

configurations


Explanation/Reference:Explanation:A logical diagram can be used to show service components and how they relate to each other. A logicaldiagram is a high-level diagram that is independent of the hardware used for the solution. It shows componentsand relationships. In this example, the diagram would should the number of datastores, size, and logic, such asreplication and other settings.

QUESTION 18You are working as a platform designer for a large hosting provider. You are considering the scalability of asolution that is projected as 50 hosts and 1,500 virtual machines. A VCSA is a project requirement. Which ofthe following is true?

A. The VCSA will scale to 5 hosts and 50 VMs and thus is a risk to project scalability.B. The VCSA can be configured to use a remote SQL database to meet project scalability.C. The VCSA should be configured to use a remote DB2 or Oracle database.


Explanation/Reference:Explanation:

A VCSA is a premade virtual machine. Due to the size of the system and the local DB2components, the systemis limited in support. However, if you expand the virtual machine resources and deploy a remote database, theVCSA can scale out to the vCenter standard limitations.

QUESTION 19A host has four dual-port network cards. What is the maximum number of vSwitches that can be integrated withthe physical network, assuming that network redundancy is not a requirement?

A. 8B. 4C. 64D. 512


Explanation/Reference:Explanation:An ESXi physical NIC can be assigned to only one vSwitch at a time. For example, a host with five NICs canhave a maximum of five vSwitches that can link to the outside world.

QUESTION 20

How do you understand and predict the resources available for VMware HA to meet specific projectrequirements?

A. Configure the appropriate admission control policyB. Disable admission control policy


Explanation/Reference:Explanation:An admission control policy tells VMware HA how to calculate the resources it needs to reserve for a cluster. Ituses a combination of memory and CPU reservation configuration or, if no configuration exists, a default lowreservation.

QUESTION 21VMware HA can protect application corruption issues by using VM monitoring functionality.

A. TrueB. False


Explanation/Reference:Explanation:VM monitoring is the function whereby a virtual machine is restarted when the virtual machine heartbeat hasstopped (such as with a blue screen of death on a Windows machine). The machine is simply restarted on thesame host (that is, not migrated). However, the system would lose data from the point of corruption.

QUESTION 22During a vCenter outage caused by a host power issue, a member of the operations team created anemergency guest VM by connecting directly to one of the hosts. The cluster was enabled for VMware HA at thetime of the vCenter outage. In the event of further problems in the datacenter, is the newly created VMprotected by HA?

A. YesB. No


Explanation/Reference:Explanation:The vCenter manages the update of the VMware HA protected list. When you add a machine while the vCenteris out of service, the list will not be updated.

QUESTION 23When designing a system for VMware HA functionality, which of the following considerations is not an impact tothe design?

A. The size of the hostB. The number of hostsC. Application compatibility with VMware platforms using HA


Explanation/Reference:Explanation:The simplicity of VMware HA is one of the many design benefits. If an application or guest virtual machine isrunning on a vSphere platform, the system is compatible from a high level with VMware HA. It is purely anautomated restart from a functionality perspective.

QUESTION 24The method of guest VM backup can have an effect on the size of datastores used in a vSphere platform.

A. TrueB. False


Explanation/Reference:Explanation:The RTO and RPO requirements and available hardware used in a solution can impact the size of datastoresby limiting the amount of data that can be practically restored. This amount of data is the max size of thedatastore.

QUESTION 25You have been sent a query regarding a platform you have just designed and implemented. Following amaintenance window where VMware HA was disabled, the VMware HA settings were lost. How would youprevent this issue?

A. Back up the vCenter database and restore it if the problem reoccurs.B. Instruct the team to use the Host monitoring tab functionality.C. Instruct the team to use the VM monitoring tab functionality.


Explanation/Reference:Explanation:Disabling the vSphere HS cluster settings will change the entire configuration of the cluster from the HSperspective. If the Host Monitoring checkbox is selected, it will allow the configuration to remain; however, theisolation response or outage response will not occur.

QUESTION 26VMware HA in vSphere 5.0 cannot survive more than five primary host failures. Thus, hosts should bephysically placed in different racks, where possible, to avoid substantial impact.

A. TrueB. False


Explanation/Reference:Explanation:This was true for VMware HA solutions prior to version 5. vSphere 5 can withstand multiple failures and uses amaster/slave topology with a reelection process.

QUESTION 27A guest VM has an 8 GB allocated to it. What is the size of the swap file?

A. 8 GB minus the reservationB. It depends on the limit configuration.C. 8 GB


Explanation/Reference:Explanation:The size of the swap space is the maximum amount of allocated memory that could be reallocated to anotherVM in the event of contention. This is expressed as the size of configured memory minus the reservation.

QUESTION 28Which of the following settings could be utilized when performing a performance test on an application server?

A. CPU LimitsB. Share ValuesC. Reservations


Explanation/Reference:Explanation:To accurately understand the resource allocation, and compare against other tests in a virtual or physicalplatform, an administrator can guarantee resources.

QUESTION 29How many vApps can a guest virtual machine be placed into?

A. 1B. 64C. 8D. 12


Explanation/Reference:Explanation:A vApp is a logical container of guest virtual machine objects. The use of a container provides the ability to usekey management functionality, which can dramatically help a virtualized platform. Automation allows lots of VMsto be managed by fewer staff. Although vApps can be nested, a single virtual machine can be defined in onlyone vApp.

QUESTION 30

vApp startup order can be configured to work with VMware Heartbeat status.

A. TrueB. False


Explanation/Reference:Explanation:A vApp is a logical container of guest virtual machine objects. The use of a container provides the ability to usekey management functionality, which can dramatically help a virtualized platform. Automation allows lots of VMsto be managed by fewer staff. The virtual machine Heartbeat is part of the VMware tools service. Otherapplication services can be made a high priority or a parent of the VMware Tools service; in this case, onstartup, waiting for the VMware tools service to start before starting the next guest virtual machine in the vAppwould assume that the application service has started successfully.

QUESTION 31A guest VM has 50 GB allocated to it and a 2 GB limit. What is the size of the swap file?

A. 50 GB minus the reservationB. 48 GB minus the reservationC. 52 GB minus the reservationD. 2 GB minus the reservation


Explanation/Reference:Explanation:The size of the swap space is the maximum amount of allocated memory that could be reallocated to anotherVM in the event of contention. This is expressed as the size of configured memory minus the reservation.

QUESTION 32Application performance test cases are most accurate if based on ____________.

A. quantitative success criteriaB. vendor best practices


Explanation/Reference:Explanation:The best validation is to place a platform under a typical test of what it will be faced with in the field--forexample, having a simulated number of users go through a workflow (perhaps a website). A lot of these tasksvary with the type of application and are primarily application functionality based. In addition, platform orinfrastructure metrics are key for validation and for information to be used within the operational documentation(for example, troubleshooting guide, monitoring recommendations).

QUESTION 33An installation guide should contain _____________. (Choose two)

A. basic troubleshooting and baseline monitoring for verification purposes

B. entry criteria or requirementsC. justifications for design choicesD. best practices.

Correct Answer: ABSection: (none)Explanation

Explanation/Reference:Explanation:An installation guide provides engineers a detailed reference and process to install and verify a solution. Allrelevant components and processes are detailed. It is also useful to include troubleshooting or known issues, ifany were experienced during the development and test phases.

QUESTION 34An implementation plan should contain _____________.

A. a milestone planB. risks, assumptions, and dependencies on the activities in the implementation planC. order


Explanation/Reference:Explanation:An implementation plan gives all members of a project team a level of understanding of the technical approachof a project, the number of phases, major tasks in each phase, and the correct order for completing the tasks.

QUESTION 35You are a VMware consultant for a large enterprise running VMware vSphere 4.1. You are reviewing theupgrade documentation created to take the company to version 5.X of the software. The upgrade has severalrequirements, including the following:

- Minimize the impact to the business applications- Do a full rollback, if required, for any issues not foreseen by the project team

You notice in the documentation that the upgrade to VMFS 5 is mentioned as being non-disruptive and havingzero impact on the technical solution. Is this technically correct?

A. YesB. No


Explanation/Reference:Explanation:In this example, a VMFS 5 upgrade cannot be rolled back without extra scratch space and without usingstorage vMotion. These things could add extra I/O load on the systems and affect the first requirement.

QUESTION 36An implementation plan is a set of instruction that provide sufficient detail for an engineer to configure or installa platform according to a physical design.

A. TrueB. False


Explanation/Reference:Explanation:An implementation plan gives all members of a project team a level of understanding of the technical approachof a project, the number of phases, the major tasks in each phase, and the correct order for completing thetasks. This documentation can be used to bring in skilled people and to judge the project stability and progressthroughout the implementation. The plan should be detailed enough for technical personnel to understand thetasks being completed but without detailing specific configuration and installation processes.

QUESTION 37A validation plan is a set of processes which prove that a project or a function of a platform has beenconfigured correctly and behaves as designed.

A. TrueB. False


Explanation/Reference:Explanation:A validation plan can range from a detailed test plan to high-level statements. It should not be subjective. Thebest validation is to place a platform under a typical test of what it will be faced with in the field--for example,having a simulated number of users go through a workflow (perhaps a website). A lot of these tasks vary withthe type of application and are primarily application functionality based. In addition, platform or infrastructuremetrics are key for validation and for information to be used within the operational documentation (for example,troubleshooting guide, monitoring recommendations).

QUESTION 38For effective VMware platform validation to take place, that platform should be _____________.

A. running test guest workloadsB. running workloads of projected application resource requirementsC. stress tested until failure to understand capacity


Explanation/Reference:Explanation:A validation plan can range from a detailed test plan to high-level statements. It should not be subjective. Thebest validation is to place a platform under a typical test of what it will be faced with in the field--for example,having a simulated number of users go through a workflow (perhaps a website). A lot of these tasks vary withthe type of application and are primarily application functionality based. In addition, platform or infrastructuremetrics are key for validation and for information to be used within the operational documentation (for example,troubleshooting guide, monitoring recommendations).

QUESTION 39Vendor support may prevent an application from being virtualized.

A. TrueB. False


Explanation/Reference:Explanation:Good design should meet the project requirements and consider the properties of assumed platform design.Protecting data requires that a system be available and manageable, that it have good performance, and that itbe easy to recover and be secure. In this example, if an application is not supported by the vendor, thebusiness may be unable to meet SLAs.

QUESTION 40Which of the following are the infrastructure qualities?

A. Availability, manageability, best practices, scalability, backupB. Availability, manageability, performance, recoverability, securityC. CPU, memory, network, storageD. Management, virtual machine, compute, network, storage

QUESTION 41The recovery point objective is the point in time to which a system needs to be restored following a failure.

A. TrueB. False


Explanation/Reference:Explanation:The recovery point objective (RPO) is the point in time to which the system needs to be restored following afailure.

QUESTION 42Which of the following factors should influence the decision of whether to virtualize an application? (Choosethree)

A. Whether it is supported on a virtualization platformB. Licensing costs in a virtualization platformC. Compliance considerations (such as inability to share infrastructure due to regulations)D. Whether the software is custom and has not be widely virtualized in the field

Correct Answer: ABCSection: (none)Explanation

Explanation/Reference:Explanation:Good design should meet the project requirements and consider the properties of assumed platform design.Protecting data requires that a system be available and manageable, that it have good performance, and that itbe easy to recover and be secure.

QUESTION 43Which of the following describes the anticipated time until a solution component may fail?

A. Recovery time objectiveB. Recovery point objectiveC. Mean time between failures


Explanation/Reference:Explanation:The recovery time objective (RTO)--also known as the return to operation--is the amount of time it takes torestore a service after a failure has taken place. The recovery point objective (RPO) is the point in time to whichthe system needs to be restored following a failure. The MTBF is the amount of time a component is predictedto fail and can be used with operational management or design concepts.

QUESTION 44You are a VMware platform designer at a large service provider reviewing a network design.

Two of the requirements are as follows:

- R001: All traffic must be encrypted or separated.- R002: All components must be fault tolerant.

The current design involves software-based iSCSI storage with teamed 1 GB network cards for the storagenetwork. The iSCSI network has a unique VLAN and network ID. The design ensures that a different passwordis used for each LUN.The current design meets both requirements.

A. TrueB. False


Explanation/Reference:Explanation:By using NIC teaming, iSCSI is configured in a fault-tolerant manner. However, it is not encrypted but isseparated; therefore R001 and R002 are satisfied.

QUESTION 45The use of software-based iSCSI storage allows encryption to be used in logical designs.

A. True

B. False


Explanation/Reference:Explanation:iSCSI traffic is not encrypted by default. However, CHAP can be used with software-based iSCSI.

QUESTION 46Which of the following is a logical boundary for vMotion?

A. ClusterB. vDCC. FolderD. Resource Pool


Explanation/Reference:Explanation:By design, vMotion is possible from a logical perspective between the vDC. It is possible, however, to have astretched cluster and to not satisfy vMotion requirements. The logical boundary is limited to vDCs.

QUESTION 47You have been asked to design a system with the following VMware functionality enabled:- R001: VMware HA must be functional.- R002: VMware SRM can be used between two sites for DR processes.- R003: You must be able to see all hosts from a single pane of glass.

From these requirements:

A. A vSphere 5.0 VCSA can provide an acceptable solution.B. A vSphere 5.0 Windows-based vCenter can provide an acceptable solution.C. The requirements cannot be met.


Explanation/Reference:Explanation:The VCSA can function with VMware SRM. However, for SRM functionality, both sites require a vCenterinstallation. This would limit the choice of single-glass-pane management to Linked mode. A Linked modeinstallation requires Microsoft technology in the ADAM instance, and thus eliminates the VCSA choice.

QUESTION 48When using VMware HA, the larger the consolidation ratio, the smaller the potential impact to the business inthe event of a VMware HA event.

A. TrueB. False

Correct Answer: B

Section: (none)Explanation

Explanation/Reference:Explanation:VMware HA can satisfy the majority of RTO scenarios. In general, businesses can tolerate small outages ofshorter than a few minutes. Designed correctly, HA can satisfy this requirement while providing hardware-levelprotection. Some design considerations are the restart time and impact of the outage; the fact that the moreVMs per host, the higher the consolidation ratio; and the possibly longer time to restart along with its largerimpact to the business.

QUESTION 49When deploying a vCenter solution for a vSphere design, continuous uptime is stated as a requirement.

The use of vCenter heartbeat has been agreed upon and budgeted. The design consists of two VCSAs.

A. TrueB. False


Explanation/Reference:Explanation:vCenter heartbeat requires a Windows-based vCenter installation, rather than the appliance.

QUESTION 50A functional requirement ____________.

A. specifies what the system should do


B. is a detail that happens to be true but has not been tested or verifiedC. specifies how the system should behaveD. is an attribute that can prevent the completion of the project


Explanation/Reference:Explanation:A functional requirement states something the system should do (for example, the system should processtransactions). A nonfunctional requirement states how the system should behave (for example, the systemshould update its performance metrics every 5 seconds). An assumption is a detail that happens to be true buthas not been tested or verified is an assumption, and a risk is an attribute that can prevent ta project from beingcompleted.

QUESTION 51A ____________ is an iterative process used to define a technical solution.

Explanation/Reference:Explanation:A design methodology is an iterative process used to create a technical design.

QUESTION 52A ______________ design requires IP addresses and specific hardware selections.

A. conceptualB. physicalC. logicalD. None of the above


Explanation/Reference:Explanation:A conceptual design is a high-level overview of the suggested system. Logical designs show how subsystemsinterconnect or communicate. No attempt is made to select vendors or map out physical products; rather, thelogical design shows how the suggested components align together. A physical design puts specificcomponents and settings into place. It lists items such as vendor products, IP addresses, and specificcommunication protocols. A physical design is a blueprint of an architecture.

QUESTION 53Which design is created first?

A. Conceptual designB. Physical designC. Logical designD. None of the above


Explanation/Reference:Explanation:A conceptual design is a high-level overview of the suggested system. The conceptual design is created firstand is usually the starting point for the logical design.

QUESTION 54Best practices should always be followed.

The company is using a "dev-ops" approach and has engaged with youat the beginning of the first planning meeting/pre-sprint.The software has yet to be written. However, you have some high-level specifications that are subject tochange at each of the early meetings.

The ______ is more logical for virtual machine sizing.

A. predictive sizing approach based on current softwareB. adaptive sizing approach

Correct Answer: BSection: Predictive/AdaptiveExplanation

Explanation/Reference:Explanation:There are two types of scaling approaches in virtual platforms: adaptive and predictive. Both approaches areusable; however, a designer must work out which is the best approach for each project.

The adaptive approach to guest virtual machine design is a major advantage that virtualization technologybrings to a datacenter. It allows a guest virtual machine to be created initially on a few metrics or high-levelrequirements (such as a limited budget) and scaled (that is, grown, not shrunk) through the virtual machinelifecycle. In many cases, this scaling can be performed hot/live without outage/downtime to the runningapplications.

The predictive approach, on the other hand, requires more planning and research, and you must know themetrics before deployment. The advantage here is that once the virtual machine has been deployed, onlyapplication maintenance is required. The application requirements are known.

Chapter 6, Validation, Thoughts, and Processes

QUESTION 138At a late stage in the software development life cycle of a production application developed in- house, anunfortunate issue was identified when the application was deployed to the production vSphere cluster. Theproduction core stacked switch has capacity issues, and this is having a serious impact on all applications forwhich the switch is providing network services. Within the test system, the application works as intended in thesingle test VLAN and with a single-host configuration.

Which of the following could be tried to help in this situation, from a vSphere perspective? (Choose two)

Case Study Title (Case Study):You are the technical designer for a vSphere platform transformation project. After conducting SME interviewsand using various platform information-gathering methods, you have created a high-level design document.

This document specifies the following:

Requirements:

R1. The solution must not have a single point of failure.R2. Production applications must not have an outage of more than 10 seconds.R3. Data must be based in the UK.R4. There is a 7-year retention policy for contracts.R5. Applications should support existing and developing workloads for the next 3 years' growth.

Spec of servers:

Web 1 vCPU, 2 GB RAM, 100 GB storage

App 1 vCPU, 4 GB RAM, 100 GB storageDB 2 vCPU, 16 GB RAM, 750 GB storage

A. Redevelop the application for a virtual platformB. Place the application into a single-vApp networkC. Add DRS rules to keep network traffic within the same host, where possibleD. Configure network I/O control


Explanation/Reference:Explanation:If you limit the application traffic to a specific dedicated network (that is, a separate VLAN) and using enforcedDRS affinity rules, the application traffic will not traverse the ESXi host's physical network interfaces.
