- A
The output displays the number of packets that matched each class in the CoPP policy.
Correct. The command shows per-class packet and byte counters for matched traffic.
- B
The output includes the number of packets dropped by each class due to policing.
Correct. The command displays drop counters for each class where a police or drop action is configured.
- C
The output shows the routing table entries that are affected by the CoPP policy.
Why wrong: Incorrect. The command does not display routing table information; it only shows CoPP policy statistics.
- D
The output displays the CoPP policy applied to each physical interface.
Why wrong: Incorrect. CoPP is applied to the control plane, not physical interfaces. 'show policy-map interface' shows per-interface policies.
- E
The output includes the ARP cache entries that are protected by CoPP.
Why wrong: Incorrect. ARP cache is not displayed by this command; it shows only CoPP policy statistics.
Quick Answer
The correct answer is that the output includes the number of packets dropped by each class due to policing. This is true because the show policy-map control-plane command reveals the applied Control Plane Policing (CoPP) policy, displaying per-class statistics such as classified packets, bytes, and specifically the drop counts resulting from the configured police action. On the Cisco CCNP ENARSI 300-410 exam, this command tests your ability to verify that CoPP is protecting the control plane from excessive traffic without disrupting legitimate protocols; a common trap is confusing this output with show policy-map interface, which shows per-interface statistics rather than control-plane class maps. Remember that CoPP operates on the control plane itself, not on individual interfaces, so the drop counters here reflect packets discarded by the policy before they reach the CPU. A helpful memory tip is "CoPP drops are CPU saves"—if you see drop counts climbing in the control-plane policy, the router is successfully throttling unwanted traffic to protect its processor.
300-410 Control Plane Policing (CoPP) Practice Question
This 300-410 practice question tests your understanding of control plane policing (copp). Examine the command output carefully: the correct answer depends on what the output actually shows, not on general recall alone. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
Which TWO statements about the 'show policy-map control-plane' command output are true? (Choose TWO.)
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 output displays the number of packets that matched each class in the CoPP policy.
The 'show policy-map control-plane' command displays the applied CoPP policy, including per-class statistics such as classified packets, bytes, and drop counts. It shows the policy name, class maps, and actions (police, drop, etc.). It does not show per-interface statistics (that would be 'show policy-map interface'), nor does it show the routing table or ARP cache.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
- Use explanations to understand the rule behind the answer.
TExam Day Tips
- Underline the problem statement mentally.
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A practitioner preparing for the 300-410 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
