Suggested answer: C

Explanation:

This is because the CoPP configuration shown in the exhibit applies a service policy to the control plane of the router, which is responsible for processing the routing protocols, management protocols, and other control traffic. The service policy uses a class map that matches the access list 100, which permits the traffic with the source IP address 10.1.1.1. The service policy also uses a policy map that sets the committed information rate (CIR) for the matched traffic to 64 kbps, which means that the traffic is guaranteed to have a minimum bandwidth of 64 kbps. The policy map also sets the exceed action to drop, which means that any traffic that exceeds the CIR will be dropped. Therefore, the traffic that matches entry 10 of ACL 100 is always allowed with a limited CIR, and any excess traffic is dropped. The source of this answer is the Cisco ENCOR v1.1 course, module 6, lesson 6.3: Implementing QoS.
