Quick Answer
The answer is 30 minutes. In Flexible NetFlow, the active flow timeout defines the maximum duration a flow can remain in the cache before it is forcibly exported, even if packets are still being received. This default of 30 minutes prevents long-lived flows from consuming cache resources indefinitely, ensuring that stale or persistent sessions are periodically aged out and reported. On the Cisco CCNP ENARSI 300-410 exam, this concept tests your understanding of flow aging mechanisms and their impact on network monitoring accuracy. A common trap is confusing the active timeout with the inactive timeout, which defaults to 15 seconds and triggers export when no new packets arrive. Remember the mnemonic: “Active is half an hour, inactive is half a minute”—30 minutes for active, 15 seconds for inactive.
This 300-410 practice question tests your understanding of netflow and flexible netflow. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. 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.
What is the default value for the 'active flow timeout' in a Flexible NetFlow monitor on Cisco IOS-XE?
15 minutes
Why wrong: 15 minutes is not the default; it can be configured but is not default.
30 minutes
Correct. The default active flow timeout is 30 minutes.
60 minutes
Why wrong: 60 minutes is not the default; it is a common custom value.
5 minutes
Why wrong: 5 minutes is too short for active timeout.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
30 minutes
The default active flow timeout is 30 minutes, after which long-lived flows are exported regardless of activity.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
15 minutes
Why it's wrong here
15 minutes is not the default; it can be configured but is not default.
30 minutes
Why this is correct
Correct. The default active flow timeout is 30 minutes.

5 minutes
Why it's wrong here
5 minutes is too short for active timeout.
Common exam traps
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
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.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
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.
