350-401 Practice Question: Runs the following command on Switch SW8: SW8#…
A network engineer runs the following command on Switch SW8:
SW8# show monitor session 8
Session 8 --------- Type : Remote Source Session Source VLANs : Both : 30 Destination Ports : Gi1/0/30
Encapsulation : Replicate
Based on this output, what can be concluded?
⚠ Common exam trap
Cisco often tests the distinction between local SPAN, RSPAN, and ERSPAN, and the trap here is that candidates confuse 'Remote Source Session' with a local SPAN or assume 'Both' means only one direction is captured.
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
✓
All traffic on VLAN 30 is mirrored and sent to a remote VLAN via Gi1/0/30.
The output shows a Remote Source SPAN (RSPAN) session, where traffic on VLAN 30 (both sent and received) is replicated and sent out destination port Gi1/0/30. The 'Encapsulation: Replicate' indicates that the mirrored frames are forwarded unchanged to the destination port, which is typically connected to an RSPAN VLAN for transport to a remote monitoring device. Therefore, all traffic on VLAN 30 is mirrored and sent via Gi1/0/30 to a remote VLAN.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
All traffic on VLAN 30 is mirrored and sent to a remote VLAN via Gi1/0/30.
Why this is correct
The type 'Remote Source Session' and Replicate encapsulation indicate RSPAN.
- ✗
This is a local SPAN session that monitors VLAN 30.
Why it's wrong here
The type is Remote Source, not Local.
- ✗
Only received traffic on VLAN 30 is captured.
Why it's wrong here
Both directions are captured.
- ✗
The destination port Gi1/0/30 is used to receive mirrored traffic.
Why it's wrong here
In a source session, the destination port sends traffic out.
