Which three statements accurately describe duplex and speed settings on Cisco 2960 switches?

(Choose three.)

When the speed is set to 1000 Mb/s, the switch ports will operate in full-duplex mode.

An autonegotiation failure can result in connectivity issues.

By default, the autonegotiation feature is disabled.

Enabling autonegotiation on a hub will prevent mismatched port speeds when connecting the hub to

the switch.

The duplex and speed settings of each switch port can be manually con�gured.

By default, the speed is set to 100 Mb/s and the duplex mode is set to autonegotiation.

By default, autonegotiation is enabled on a Catalyst 2960 switch. However, the duplex and speed

settings can be manually con�gured for each switch port. If the speed is set to 1000 Mb/s, the switch

ports will operate in full-duplex mode. Switches, not hubs, can be con�gured for auto negotiation.

When creating an IPv6 static route, when must a next-hop IPv6 address and an exit interface both be

speci�ed?

when CEF is enabled

when the static route is a default route

when the next hop is a link-local address

when the exit interface is a point-to-point interface

Link-local addresses are only unique on a given link, and the same address could exist out multiple

interfaces. For that reason, any time a static route speci�es a link-local address as the next hop, it must

also specify the exit interface. This is called a fully speci�ed static route.

Refer to the exhibit. Which password will the administrator need to use on this device to enter

privileged EXEC mode?

Cisco

class

password

cisco

Refer to the exhibit. OSPFv2 has been con�gured on router R1, and the router-id command has not

been manually con�gured. When the network administrator reboots router R1, what will be the value

of the OSPF router ID?

172.16.1.1

192.168.2.254

10.15.15.1

10.0.10.2

If the router ID is not exactly speci�ed by the router-id command, then the highest IPv4 address on any

con�gured loopback interface(s) would become the router ID.

A network administrator is using the router-on-a-stick model to con�gure a switch and a router for

inter-VLAN routing. What con�guration should be made on the switch port that connects to the router?

Con�gure the port as an access port and a member of VLAN1.

Con�gure the port as an 802.1q trunk port.

Con�gure the port as a trunk port and assign it to VLAN1.

Con�gure it as a trunk port and allow only untagged tra�c.

The port on the switch that connects to the router interface should be con�gured as a trunk port. Once

it becomes a trunk port, it does not belong to any particular VLAN and will forward tra�c from various

VLANs.

A network administrator is designing an IPv4 addressing scheme and requires these subnets.

1 subnet of 100 hosts

2 subnets of 80 hosts



Which combination of subnets and masks will provide the best addressing plan for these requirements

9 subnets of 126 hosts with a 255.255.255.128 mask





1 subnet of 126 hosts with a 255.255.255.192 mask



IPv4 subnets that require 100 and 80 hosts are provided by creating subnets of 126 usable addresses,

each of which requires 7 host bits. The resulting mask is 255.255.255.128.

Subnets that require 30 and 20 hosts are provided by creating subnets of 30 usable addresses, each of

which requires 5 host bits. The resulting mask is 255.255.255.224.

Creating nine subnets, each consisting of 126 usable addresses, would waste large numbers of

addresses in the six smaller subnets.

22

Refer to the exhibit. A network administrator has con�gured R2 for PAT. Why is the con�guration in?

The static NAT entry is missing.

NAT-POOL2 is bound to the wrong ACL.

The ACL does not de�ne the list of addresses to be translated.

The overload keyword should not have been applied.

In the exhibit, NAT-POOL 2 is bound to ACL 100, but it should be bound to the con�gured ACL 1. This

will cause PAT to fail. 100, but it should be bound to the con�gured ACL 1. This will cause PAT to fail.

Refer to the exhibit. Which two statements are based on the output as shown in the exhibit? (Choose

two.)

The output is the result of the show ip nat translations command.

The host with the address 209.165.200.235 will respond to requests by using a source address of

192.168.10.10.

The host with the address 209.165.200.235 will respond to requests by using a source address of

209.165.200.235.

Tra�c with the destination address of a public web server will be sourced from the IP of 192.168.1.10.

The output is the result of the show ip nat statistics command.

The output displayed in the exhibit is the result of the show ip nat translations command. Static NAT

entries are always present in the NAT table, while dynamic entries will eventually time out.

26





Refer to the exhibit. Interfaces Fa0/5, Fa0/7, and Fa0/9 are the only connected ports on the switch

CiscoSwitch. All other ports are unused. Which security best practice did the administrator forget to

con�gure?

Change the native VLAN to a �xed VLAN other than VLAN 1.

All active user ports are associated with VLANs distinct from VLAN 1 .

Delete VLAN 1 from the switch CiscoSwitch.

Con�gure all unused ports to a ‘black-hole’ VLAN that is not used for anything on the network.

All access ports are placed in VLAN 1 by default. This VLAN is the default VLAN and cannot be deleted

or renamed. Security best practices dictate that user ports should be changed to something other than

VLAN 1 with the command switchport access vlan ID.

_______________________________________________________________

27




Refer to the exhibit. Interfaces Fa0/2, Fa0/4, and Fa0/6 are connected to users on the data network of a

switch named CiscoSwitch. Interface Fa0/24 is connected to a �le server on the management network.

All other ports are unused. Which security best practice did the administrator forget to con�gure?

Con�gure all unused ports to a ‘black-hole’ VLAN that is not used for anything on the network.

Change the native VLAN to a �xed VLAN other than VLAN 1.

Disable autonegotiation on interfaces that are not being utilized as a trunk.

Delete VLAN 1 from CiscoSwitch.

Cisco switches use DTP to autonegotiate between each other. It is recommended to disable

autonegotiation to prevent any malicious users from forming a trunk with the Cisco switch on

nontrunking interfaces.

A network engineer is con�guring PAT on a router and has issued the command:

ip nat source list 1 interface serial 0/1/0 overload

Which additional command is required to specify addresses from the 192.168.128.0/18 network as the





inside local addresses?

access-list 1 permit 192.168.128.0 255.255.192.0



ip nat inside source list 1 pool INSIDE_NAT_POOL

ip nat inside source static 192.168.128.0 209.165.200.254

A standard access list with the appropriate wildcard mask speci�es the inside local addresses to be

translated. The ip nat inside source list 1 pool NAT_POOL command con�gures NAT to use a pool of

outside global addresses, not a single outside interface address as required. The ip nat inside source

static 192.168.128.0 209.165.200.254 command con�gures one-to-one static NAT, not PAT as the

overload keyword speci�es.

Which three statements describe a DHCP Discover message? (Choose three.)

The source MAC address is 48 ones (FF-FF-FF-FF-FF-FF).

The destination IP address is 255.255.255.255.

The message comes from a server o�ering an IP address.

The message comes from a client seeking an IP address.

All hosts receive the message, but only a DHCP server replies.

Only the DHCP server receives the message.

37

Which two issues might cause excessive runt and giant frames in an Ethernet network? (Choose two.)

native VLAN mismatch

damaged cable connector

a malfunctioning NIC






excessive collisions

using the in cable type

inly con�gured auto-MDIX feature

In an Ethernet network, a runt is a frame that is shorter than 64 bytes and a giant is a frame that is

longer than the maximum allowed length. Both are often caused by NIC malfunctioning, but can also be

caused by excessive collisions. CRC errors usually indicate a media or cable error caused by electrical

interference, loose or damaged connections, or using the in cabling type.

Fill in the blank.

A late collision occurs after 512 bits of a frame have been transmitted.

Which series of commands will cause access list 15 to restrict Telnet access on a router?

R1(con�g)# line vty 0 4

R1(con�g -line)# access-class 15

R1(con�g)# line vty 0 4

R1(con�g -line)# ip access-group 15 in

R1(con�g)# int gi0/0

R1(con�g -if)# access-class 15 in

R1(con�g)# int gi0/0

R1(con�g -if)# ip access-group 15 in

Once an access list to restrict Telnet or SSH access has been created, it is applied to the vty lines with

the access-class command. This will restrict Telnet or SSH access.

A user calls the help desk to report that a Windows XP workstation is unable to connect to the network





after startup and that a popup window says “This connection has limited or no connectivity.” The

technician asks the user to issue the ipcon�g /all command. The user reports the IP address is

169.254.69.196 with subnet mask of 255.255.0.0 and nothing is displayed for the DNS server IP address.

What is the cause of the problem?

The workstation NIC has malfunctioned.

The subnet mask was con�gured inly.

The DNS server IP address needs to be con�gured.

The workstation is unable to obtain an IP address from a DHCP server.

Open the PT Activity. Perform the tasks in the activity instructions and then answer the question.

Which code is displayed on the web browser?

Great!

It works!

Welldone!

Inter-VLAN con�gured!
