Question 1

Refer to the exhibit.

IS-IS is the routing protocol on the network. After the team noticed excessive CPU usage on all routers, particularly routers R2 and R6, they configured route summarization on all routers. However, a network engineer noticed that summary routes and more specific routes are present in the routing table on R1. Which action must the team take so that R1 receives only the summary routes?

Options :

A : Configure R2 and R4 to perform summarization for Level 1 routers.

B :

Configure R3 to perform summarization for Level 1 routers, and configure R6 to perform summarization for Level 2 routers.

C : Configure R3 and R5 to perform summarization for Level 1 and Level 2 routers.

D : Configure R6 only to perform summarization for all routers.

Answer: B

Question 2

Refer to the exhibit.

Refer to the exhibit. After a recent network implementation project, customer A is performing stress testing to verify network redundancy at the branch office connected to R4. When the link from R2 is shut own as shown, the SLA tracking object fails and the cost of the link between R2 and R4 increases to 100. However, a traceroute operation from a PC in the Branch office shows that traffic to HQ is still routed via R2. Which solution corrects the problem and optimizes traffic flow via R3 without creating operational overhead?

Options :

A : Configure two OSPF processes on R2 and R3 and redistribute traffic between them.

B : Redistribute routes from BGP to OSPF as type El.

C : Use multiarea adjacency to extend Area 10 to the link between R2 and R3.

D : Create a virtual channel from R3 to R4.

Answer: B

Question 3

Which two BGP route reflector attributes should be implemented to prevent routing loops? (Choose two)

Options :

A : CLUSTER_ID

B : ORIGINATOR_ID

C : CLUSTER_LIST

D : COMMUNITY

E : AS_PATH

Answer: B,C

Question 4

After changing the IP address on an IOS XR router, an engineer cannot ping the new address Which step did the engineer forget to complete?

Options :

A : commit the configuration

B : roll back the configuration

C : save the running configuration

D : merge the configuration

Answer: A

Question 5

Refer to the exhibit.

R1 is directly connected to R2 and R3. R1 is in BGP AS 123, R2 is in BGP AS 2, and R3

is in BGP AS 3. Assume that there is no connectivity issue between R1, R2 and R1, R3. Which result between

BGP peers R1, R2 and R1, R3 is true?

Options :

A : The BGP session does not come up between R1 and R2 and between R1 and R3.

B : The BGP session comes up between R1 and R2 and between R1 and R3.

C : The BGP session comes up between R1 and R3, but not between R1 and R2.

D : The BGP session comes up between R1 and R2, but not between R1 and R3
