Question 1,069 of 2,152

Device Management →hardMultiple ChoiceObjective-mapped

Quick Answer

The answer is that some management traffic is being dropped because it exceeds the configured police rate. This is evident from the show policy-map control-plane output, where the MANAGEMENT class has 100 offered packets, but only 95 conformed and were transmitted, while 5 packets exceeded the police rate of 8000 bps and were dropped. Control plane policing verification is critical for the Cisco CCNP ENARSI 300-410 exam, as it tests your ability to interpret how CoPP protects the router’s control plane from excessive traffic by applying a policer to specific class maps. A common trap is focusing only on the conformed packets and missing the exceeded counter, which directly indicates drops. Remember the memory tip: “Conformed goes through, exceeded is chewed”—the exceeded count always signals dropped traffic when the action is drop.

300-410 Device Management Practice Question

This 300-410 practice question tests your understanding of device management. 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.

A network engineer runs the following command on Router R1:

R1# show policy-map control-plane

Control Plane

Service-policy input: CoPP class-map: MANAGEMENT (match-all) 100 packets, 5000 bytes 5 minute offered rate 0 bps police: 8000 bps, 1500 limit, 1500 extended limit conformed 95 packets, 4750 bytes; action: transmit exceeded 5 packets, 250 bytes; action: drop conformed 0 bps, exceed 0 bps

class-map: ROUTING (match-all) 200 packets, 10000 bytes 5 minute offered rate 0 bps police: 16000 bps, 3000 limit, 3000 extended limit conformed 200 packets, 10000 bytes; action: transmit exceeded 0 packets, 0 bytes; action: drop conformed 0 bps, exceed 0 bps

Based on this output, what is happening to traffic matching the MANAGEMENT class?

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

✓

Some management traffic is being dropped because it exceeds the configured police rate.

The output shows that for the MANAGEMENT class, 100 packets were offered, 95 conformed and were transmitted, but 5 exceeded the police rate and were dropped. This indicates some management traffic is being dropped due to policing.

Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps

Common exam trap: answer the scenario, not the keyword

Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.

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.

What to study next
