QUESTION 37
Refer to the exhibit.

provider

AS #1 and AS #2 have multiple EBGP connections with each other. AS #1 wants all return traffic that is
destined to the prefix 10.10.10.1/32 to enter through the router R1 from AS #2. In order to achieve this routing
policy, the AS 1 advertises a lower MED from R1, compared to a higher MED from R3, to their respective BGP
neighbor for the prefix 10.10.10.0/24. Will this measure guarantee that the routing policy is always in effect?
A. Yes, because MED plays a deterministic role in return traffic engineering in BGP.
B. Yes, because a lower MED forces BGP best-path route selection in AS #2 to choose R1 as the best path for 10.10.10.0/24.
C. Yes, because a lower MED in AS #2 is the highest BGP attribute in BGP best-path route selection.
D. No, AS #2 can choose to alter the weight attribute in R2 for BGP neighbor R1, and this weight value is
cascaded across AS #2 for BGP best-path route selection.
E. No, AS #2 can choose to alter the local preference attribute to overwrite the best-path route selection over the lower MED advertisement from AS #1. This local preference attribute is cascaded across AS #2 for the BGP best-path route selection.

Correct Answer: E

A. VPNv4 is not configured between PE1 and PE3.
B. address-family ipv4 vrf is not configured on PE3.
C. After you configure route-target import 999:999 for a VRF on PE3, the route will be accepted.
