• Question 36:

  Click the Exhibit button.

  

  You have deployed route reflectors in your network. You are receiving the route 200.0.0.0/24 from AS10 and AS6 and are seeing the oscillation happening as shown in the exhibit.

  What are two ways to solve this issue? (Choose two.)

  A. Configure the always-compare-med parameter on both route reflectors.

  B. Configure the add-path parameter on both route reflectors.

  C. Configure the med-plus-igp parameter on both route reflectors.

  D. Configure the as-path-ignore parameter on both route reflectors.

  Correct Answer: AC

• Question 37:

  A. multipath multiple-as

  B. family inet-vpn

  C. multihop

  D. as-override

  Correct Answer: B

• Question 39:

  How is a BGP Layer 2 VPN prefix formed by a PE?

  A. by combining the route distinguisher and vrf-target, in that order

  B. by combining the route distinguisher, remote site identifier, and site identifier, in that order

  C. by combining the route distinguisher, site identifier, and remote site identifier, in that order

  D. by combining the vrf-target and route distinguisher, in that order

  Correct Answer: C

• Question 40:

  You want to use IS-IS on a GRE interface where the underlying Layer 3 MTU is 1500.

  Which statement is correct in this scenario?

  A. IS-IS can be used because every IS-IS interface must be capable of transmitting packets at least as large as 1476 bytes, and the GRE header is 24 bytes.

  B. IS IS can be used, but the networking device directly attached to the circuit must be capable of fragmentation.

  C. IS-IS cannot be used, but the router can enable a GRE key that serves the same function as IS-IS.

  D. IS-IS cannot be used because the IS-IS hello is not allowed to be fragmented and has the DF bit set.

  Correct Answer: B
