300-410 Practice Question: Runs the following command to verify NetFlow…
A network engineer runs the following command to verify NetFlow export on an interface:
R1# show ip flow interface
GigabitEthernet0/0
ip flow ingress ip flow egress
GigabitEthernet0/1
ip flow ingress
What does this output indicate?
⚠ Common exam trap
The trap is misreading the indented output and assuming only one direction is enabled per interface, or overlooking that Gi0/1 has ingress configured — candidates often pick A by skimming.
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
✓
NetFlow is enabled on GigabitEthernet0/0 for both ingress and egress, and on GigabitEthernet0/1 for ingress only.
The 'show ip flow interface' output lists each interface and the direction(s) in which NetFlow is enabled. GigabitEthernet0/0 shows both 'ip flow ingress' and 'ip flow egress', meaning NetFlow captures traffic in both directions. GigabitEthernet0/1 shows only 'ip flow ingress', meaning only ingress traffic is captured. Option B accurately reflects this.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
NetFlow is enabled only on GigabitEthernet0/0 for both directions.
Why it's wrong here
GigabitEthernet0/1 also shows ip flow ingress, so NetFlow is enabled there for ingress, not only on GigabitEthernet0/0. The output confirms both interfaces carry flow configuration. Restricting the answer to one interface misreads the second stanza.
- ✓
NetFlow is enabled on GigabitEthernet0/0 for both ingress and egress, and on GigabitEthernet0/1 for ingress only.
Why this is correct
The output lists per-interface flow directions: GigabitEthernet0/0 has both ip flow ingress and ip flow egress configured, while GigabitEthernet0/1 shows only ip flow ingress. NetFlow therefore captures traffic in both directions on one interface and inbound only on the other.
- ✗
NetFlow is enabled on GigabitEthernet0/0 for ingress only.
Why it's wrong here
GigabitEthernet0/0 lists both ip flow ingress and ip flow egress, so egress is enabled alongside ingress. The option omits egress, misstating the configuration. Ingress-only would be correct had the egress line been absent from that interface's stanza.
- ✗
NetFlow is not enabled on any interface.
Why it's wrong here
The output explicitly lists ip flow ingress and ip flow egress under GigabitEthernet0/0 and ip flow ingress under GigabitEthernet0/1, so NetFlow is enabled. Claiming otherwise contradicts the displayed configuration. This command would show nothing if NetFlow were absent from all interfaces.
