  Refer to the exhibit.

  

  An engineer is troubleshooting IS-IS configuration between two areas. IS-IS Area-A network 30.1.1.0/24 is leaked into IS-IS Area-. R2 is failing to filter the route updates from network 10.1.1.0/24. Which configuration must the engineer apply to resolve the issue?

  A. R2(config)# ip prefix-list List2 seq 5 deny 10.1.1.0/24 R2(config)# interface fastethernet 0/0 R2(config-if)# ip router isis 100 R2(config-if)# router isis 100 R2(config-router)# distribute-list gateway List2 in

  B. R2(config)# ip prefix-list List1 seq 3 deny 10.1.1.0/24 R2(config)# ip prefix-list List1 seq 5 permit 30.1.1.0/24 ge 25 1e R2(config)# ip prefix-list List1 seq 10 permit 0.0.0.0/le 32 R2(config)# interface fastethernet 0/0 R2(config-if)# ip router isis 122 R2(config-if)# router isis 122 R2(config-router)# distribute-list prefix List1 in

  C. R1(config)# ip prefix-list List2 seq 5 deny 10.1.1.0/24 R1(config)# interface fastethernet 0/0 R1(config-if)# ip router isis 100 R1(config-if)# router isis 100 R1(config-router)# distribute-list gateway List2 in R (config-if)# router isis 150 R1(config-router)# distribute-list route-map Map1 in

  D. R2(config)# access-list 101 deny ip any 10.1.1.0 0.0.0.127 R2(config)# access-list 101 permit ip any 30.1.1.0 0.0.0.63 R2(config)# access-list 101 deny ip any 0.0.0.0 0.0.0.0 R2(config)# interface fastethernet 0/0 R2(config-if)# ip router isis 121 R2(config-if)# router isis 121 R2(config-router)# distribute-list 101 in

• Question 16:

  Refer to the exhibit.

  

  .

  R1 is expected to receive routes originating from AS 65516 and from any ASs that are directly attached to it. However, R1 is receiving routes only from AS 65516. Which action corrects the configuration?

  A. Change the regular expression in the AS-path permit filter to .*.

  B. Change the regular expression in the AS-path permit filter to ^65516_[0-9]*$.

  C. Add the regular expression ^$. in the AS-path filter to permit the traffic from R2.

  D. Change the regular expression in the AS-path permit filter to _65516_.

  Correct Answer: B

• Question 17:

• Question 19:

  What is the difference between a source tree and a shared tree in a multicast environment?

  A. To route traffic from source to receiver a source tree uses a link-state routing protocol and a shared tree uses a distance-vector routing protocol.

  B. A source tree has its root at the source, and a shared tree has its root at a designated rendezvous point.

  C. To stream multicast from source to receiver, a source tree uses PIM-SM and a shared tree uses PIM-DM.

  D. Source trees are the default type for bidirectional PIM, and PIM-DM uses shared trees by default.

  Correct Answer: B
