CCIE Data Center (legacy) — Question 102

On the Cisco Nexus 7000 Series Switch, Control Plane Policing is enforced on which component?

Answer options

• A. The supervisor module enforces CoPP before out-of-policy traffic reaches the CPU
• B. The fabric modules enforce CoPP in the fabric before out-of-policy traffic reaches the CPU
• C. The linecards enforce CoPP locally before out-of-policy traffic reaches the CPU
• D. The egress virtual output queue enforces CoPP locally before out-of-policy traffic reaches the CPU

Correct answer: C

Explanation

The correct answer is C because Control Plane Policing (CoPP) is specifically implemented on the linecards to manage traffic before it reaches the CPU. Options A and B mention enforcement at the supervisor and fabric modules, respectively, which do not directly handle CoPP enforcement. Option D refers to an unrelated component, the egress virtual output queue, which is not responsible for CoPP.
