• Question 27:

  Refer to the exhibit.

  

  A network operator is attempting to configure an IS-IS adjacency between two routers, but the adjacency cannot be established. To troubleshoot the problem, the operator collects this debugging output. Which interfaces are misconfigured on these routers?

  A. The R2 interface is configured as point-to-point, and the peer router interface is configured as multipoint.

  B. The R2 interface is configured as Level 1 only, and the peer router interface is configured as Level 2 only.

  C. The peer router interface is configured as point-to-point, and the R2 interface is configured as multipoint.

  D. The peer router interface is configured as Level 1 only, and the R2 interface is configured as Level 2 only.

  Correct Answer: B

  R2 is Sending L1 and received from Peer L2.

• Question 28:

  Refer to the exhibit.

  

  An engineer has started to configure a router for OSPF, as shown.

  Which configuration must an engineer apply on the network so that area 15 traffic from R5 to R1 will prefer the route through R4?

  A. Implement a sham link on the link between R3 and R2 to extend area 0 over area 15.

  B. Implement a multiarea adjacency on the link between R2 and R4, with the cost manipulated to make the path through R4 preferred.

  C. Place the link between R3 and R5 in a stub area to force traffic to use the route through R4.

  D. Increase the cost on the link between R2 and R3 to a value higher than the link between R2 and R4, to influence the path over R3 and R4.

  Correct Answer: B

  After doing an easy lab I can say for certain that the answer is B. To add some more information to clarify, R3 wil ALWAYS prefer the INTRA-area link to R2, no matter the cost assigned to the interface. So it is until the inter-area 0 link between R2-R4 is configured as multiarea also in area 15, that the cost of the interface comes into play.
