• Question 25:

  

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

  A. The CE-1 and CE-2 routes will have the same route distinguisher, which will stop the BGP routes from being shared.

  B. An AS loop will not exist between CE-1 and CE-2 and the BGP routes will be shared.

  C. An AS loop will exist between CE-1 and CE-2 and the BGP routes will not be shared.

  D. The CE-1 and CE-2 routes will have the same route distinguisher, which will not stop the BGP routes from being shared.

  Correct Answer: CD

• Question 26:

  You want to allow the load balancing of traffic for an EBGP route from two different peers in the same AS. Which three actions are needed to accomplish this task? (Choose three.)

However, the remote CE devices are not receiving the BGP routes.

  Referring to the exhibit, what is the problem?

  A. A route distinguisher mismatch exists.

  B. The PE devices are detecting an AS loop.

  C. The CE devices are detecting an AS loop.

  D. A VRF target community mismatch exists.

  Correct Answer: C
