QUESTION 71

While you are troubleshooting network performance issues, you notice that a switch is periodically flooding all unicast traffic. Further investigation reveals that periodically the switch is also having spikes in CPU utilization, causing the MAC address table to be flushed and relearned. What is the most likely cause of this issue?

 

A.       a routing protocol that is flooding updates

B.       a flapping port that is generating BPDUs with the TCN bit set

C.       STP is not running on the switch

D.      a user that is downloading the output of the show-tech command

E.       a corrupted switch CAM table

 

Correct Answer: B

 

 

QUESTION 72

Your network is suffering from regular outages. After troubleshooting, you learn that the transmit lead of a fiber uplink was damaged. Which two features can prevent the same issues in the future? (Choose two.)

 

A.       root guard

B.       loop guard

C.       BPDU guard

D.      UDLD

E.       BPDU skew detection

 

Correct Answer: BD

 

 

QUESTION 73

Refer to the exhibit. What can be done to remove the summary routes to Null0 on R3?

 

clip_image002

 

A.       Configure the EIGRP routing subcommand no auto-summary on 209.165.202.155.

B.       Configure the EIGRP routing subcommand no auto-summary on 209.165.202.24.

C.       Configure the EIGRP routing subcommand no auto-summary on both 209.165.202.155 and 209.165.202.242.

D.      Configure the EIGRP routing subcommand no auto-summary on R3.

 

Correct Answer: D

 

 

 

 

 

 

 

 

 

 

 

 

 

 

QUESTION 74

Refer to the exhibit. R4 is configured as a receive-only EIGRP stub, and is adjacent with 209.165.202.139 (R3). However, R4 is not learning about network 209.165.201.0/27 from R3. What could be the cause of this issue?

 

clip_image004

 

A.       R4 should learn this route from 209.165.200.242, and not from R3.

B.       R3 is configured as a receive-only EIGRP stub.

C.       R3 and R4 may be using different EIGRP process numbers.

D.      R3 and R4 are asymmetrically adjacent neighbors.

 

Correct Answer: B

 

 

QUESTION 75

Refer to the exhibit. R4 is a remote office router that is running EIGRP; the decision has been made to change EIGRP to use static EIGRP adjacencies. However, once the configuration change was applied, the adjacency between R4 and 209.165.202.139 (HQ) seems to disappear. What could be the cause of this issue?

 

clip_image006

 

A.       Static EIGRP neighbor configuration is symmetric; it causes the interface to stop processing inbound multicast packets and stop sending multicast packets.

B.       Static EIGRP neighbors are not displayed with the show ip eigrp neighbors command.

C.       A distance (internal 90 or external 170) must also be configured for the static neighbor.

D.       The neighbor 209.165.202.139 should be changed to run under EIGRP autonomous system 0.

 

Correct Answer: A

 

 

QUESTION 76

Refer to the exhibit. What problem does the debug ip ospf event output from R3 indicate?

 

clip_image008

 

A.       209.165.202.140 and R3 are not both configured as OSPF stubs.

B.       209.165.202.140 and R3 are not configured in the same OSPF area.

C.       209.165.202.140 is configured as a no-summary stub.

D.      Transit area OSPF hello packets are not processed by design.

 

Correct Answer: A

 

 

QUESTION 77

Refer to the exhibit. R4 is configured as an OSPF stub; however, R4 should still be learning the OSPF LSA type 3 interarea routes from 209.165.202.130. Which action will solve this issue?

 

clip_image009

 

A.       Remove any route maps from R4 that are filtering the incoming OSPF updates.

B.       Enable sending summary LSA’s by removing no-summary from the stub command on the ABR.

C.       Enable sending summary LSA’s by removing no-summary from the stub command on the ASBR.

D.      Control of interarea route propagation is best handled with EIGRP.

 

Correct Answer: B

 

 

QUESTION 78

Refer to the exhibit. An OSPF virtual link is configured between R4 and R3. Based upon the show command output, why is the virtual-link down?

 

clip_image011

 

A.       Virtual links cannot transit area 0.

B.       The cost of the virtual link needs to be configured as 1.

C.       The timer intervals for virtual links need to be aggressive (2, 8, 8, and 1).

D.      The virtual interface VL1 is shut down.

 

Correct Answer: A

 

 

QUESTION 79

Refer to the exhibit. An OSPF virtual link is configured between RTB and RTA. Based upon the exhibit, why is the virtual link on RTB down?

 

clip_image013

 

A.       The cost on each end of the OSPF virtual link must be identical.

B.       There is a unidirectional physical layer issue from RTB to RTA.

C.       The OSPF virtual link neighbor IP address on RTB is incorrect.

D.      The virtual link state on FastEthernet0/0 of RTA must be point-to-multipoint.

 

Correct Answer: C

 

 

QUESTION 80

Refer to the exhibit. Router 1 has three OSPF neighbors, but none of them have routes to the 10.10.10.0 network. Why?

 

clip_image014

 

A.  A metric is not defined on the redistribute statement.

B.  Redistribution cannot be done in a non-zero area.

C.  The subnets keyword should not be used.

D.  Area 1 is a stub area.

E.  Area 1 is a not-so-stubby area.

F.  A route map must be used on the redistribute statement to permit the 10.10.10.0/24 route.

 

Correct Answer: D
