• Question 64:

  

  You are providing carrier-of-carrier VPN services for AS 100 and AS 200. You want to distribute MPLS labels between your PE routers and the AS 100 and AS 200 CE routers.

  What must be enabled to accomplish this task?

  A. Use BGP with the inet-vpn address family enabled.

  B. Use BGP with the labeled-unicast address family enabled.

  C. Use RSVP with the lsp-set parameter enabled.

  D. Use RSVP with the tunnel-services parameter enabled.

  Correct Answer: A

• Question 65:

  

  A network administrator is migrating from IPv4 to IPv6 and one of the IS-IS adjacencies is not coming up between R1 and R2.

  Which action will solve the problem?

  A. Remove topologies ipv6-unicast from protocols isis on R2.

  B. Configure topologies ipv4-unicast from protocols isis on R2.

  C. Remove topologies ipv6-unicast from protocols isis on R1.

  D. Configure an IPv4 address on interface ge-0/0/1 on R1.

  Correct Answer: D

• Question 66:

  

  You have the LDP signaled VPLS topology as shown in the exhibit. CE-B at Site-2 is multihomed to both PE-2 and PE-3.

  In this scenario, where would you configure loop prevention?

  A. PE-1

  B. CE-B

  C. PE-3

  D. PE-2

  Correct Answer: A

• Question 67:

  

  You are the administrator of AS 65512. You are learning the 192.168.1.0/24 prefix from both AS 100 and AS 200. You want traffic destined to the 192.168.1.0.0/24 prefix to exit your AS towards AS 200.

  How would you accomplish this task?

  A. Configure an import routing policy on PE-2 to set a higher MED on the path learned from AS 100.

  B. Configure an import routing policy on PE-2 to modify the origin attribute on the path learned from AS

  100.

  C. Configure an import routing policy on PE-2 to set a higher local preference value on the path learned from AS 200.

  D. Configure an import routing policy on PE-2 to append the AS path attribute on the path learned from AS

  100.

  Correct Answer: C

• Question 68:

  

  All adjacencies have been formed, no extra options have been configured, and no policies have been written.

  Referring to the exhibit, which two statements are correct? (Choose two.)

  A. R2 will create a default route and send it as a TLV to R1

  B. R1 cannot reach R5

  C. R1 can reach R5

  D. R1 will create its own default route that points to R2

  Correct Answer: AC

• Question 69:

  Which two statements are correct about Opaque LSAs in OSPF? (Choose two.)

  A. Type 10 LSAs are used for MPLS traffic-engineering and have area scope.

  B. Type 11 LSAs are used for MPLS traffic-engineering and have area scope.

  C. Type 11 LSAs are used for MPLS label exchange and have link-local scope

  D. Type 9 LSAs are used for graceful-restart and have link-local scope

  Correct Answer: AD

• Question 70:

  The link between CE1 and PE1 has a history of flapping. To avoid the impact that flapping causes to the network, you decide to use route damping.

  Which statement is correct in this scenario?

  A. Dampening is enabled on interfaces.

  B. Dampened routes decay at a sliding rate known as half-life.

  C. Routes become dampened when the configured max-suppress value is reached.

  D. Dampened routes become active when their figure of merit drops below the reuse value.

  Correct Answer: D
