Which THREE symptoms indicate that NetFlow data export is failing or misconfigured? (Choose THREE.)
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 'show ip cache flow' output shows a high number of active flows but zero export packets sent.
When NetFlow export fails, the 'show ip cache flow' output will show increasing flows but no export packets. A 'show ip flow export' output with 'Export state: idle' indicates the exporter is not sending data. If the destination collector is unreachable, the router will report 'Export packets discarded' due to no route. Option B is incorrect because 'Export state: active' is normal. Option E is incorrect because 'show flow monitor cache' showing entries means flows are being cached, but export may still fail.
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 'show ip cache flow' output shows a high number of active flows but zero export packets sent.
Why this is correct
This indicates flows are being created but not exported, likely due to export configuration issues.
- ✗
The 'show ip flow export' output shows 'Export state: active'.
Why it's wrong here
This indicates normal operation; export is active and sending data.
- ✓
The 'show ip flow export' output shows 'Export state: idle'.
Why this is correct
Idle state means the exporter is not sending any flow data, often due to misconfiguration.
- ✓
The 'show ip flow export' output shows 'Export packets discarded: 150' with reason 'no route'.
Why this is correct
This indicates the router cannot reach the collector, so packets are discarded.
- ✗
The 'show flow monitor name FLOW-MON cache' output displays multiple flow entries with valid timestamps.
Why it's wrong here
This shows that flows are being cached correctly; export failure would not be visible here.
