Answers
E.

Configure IP CEF to CoPP policy and BGP to work

Suggested answer: A, B

Explanation:

The policy-map COPP-7600 only rate-limit HTTP & HTTPS traffic (based on the ACLconditions) so any BGP packets will be processed in the class "class-default", which dropsexceeded BGP packets. Therefore we have two ways to solve this problem:

+ Add BGP to the ACL with the statement "permit tcp any any eq bgp"

+ Configure higher value for CIR in default class as 2Mbps is too low for web traffic (http & https)
