A . Remove the exceed-rate command in the class map.
B. Remove the class map NMS from being part of control plane policing.
C. Configure the CIR rate to a lower value that accommodates all the NMS tools
D. Separate the NMS class map in multiple class maps based on the specific protocols with appropriate CoPP actions

Answer: D

Explanation:

Reference: https://tools.cisco.com/security/center/resources/copp_best_practices

The class-map NMS in the exhibit did not classify traffic into specific protocols so many packetswere dropped. We should create some class-map to classify the receiving traffic.

It is also arecommendation of CoPP/CPP policy:

“Developing a CPP policy starts with the classification of the control plane traffic. To that end,the control plane traffic needs to be first identified and separated into different class maps.”
