Questions # 8:

Refer to the exhibit.

Question # 8

An engineer has configured all routers in the environment to run IS-IS Level 1 and Level 2 routing. The engineer wants traffic from R1 to R5 to pass via R2. but IS-IS routing has calculated the best path via R4. Which action corrects the problem?

Options:
A.

B.

Set the link metric for the link from router R1 to router R4 to 30 or more.

C.

Set the link metric on R2 for the links from router R2 to routers R3 and R4 to 30 or more.

D.

Configure routers R1, R2, and R5 for Level 1 routing only.

Questions # 9:

Refer to the exhibit.

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_.
