Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The CoPP policy is policing control plane traffic at 1 Mbps, but no packets have been matched yet.
The output shows the CoPP policy for the control plane, with a policer that limits traffic to 1 Mbps. The counters show no traffic has been matched, which may indicate that the policy is not effective or no traffic is hitting the control plane.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
The CoPP policy is policing control plane traffic at 1 Mbps, but no packets have been matched yet.
Why this is correct
The policer is configured with CIR 1 Mbps, but counters show 0 packets.
- ✗
The CoPP policy is dropping all control plane traffic.
Why it's wrong here
The policy is policing, but no packets have been dropped because none have been matched.
- ✗
The CoPP policy is not applied to the control plane.
Why it's wrong here
The command shows policy-map control-plane, so it is applied.
- ✗
The CoPP policy is using a class-map that matches all traffic.
Why it's wrong here
The class-default matches any traffic, but the output shows no packets matched.
