350-601 Storage Network Practice Question
Which FCoE feature allows multiple VLANs to be carried over a single physical link when using FIP snooping?
⚠ Common exam trap
Cisco often tests the misconception that FIP snooping is only about security or that it is the same as FCoE VLAN mapping, but the trap here is that candidates confuse FIP snooping with VSANs or NPV, not realizing that FIP snooping specifically enables VLAN multiplexing by snooping control frames.

Correct answer & explanation
✓
FIP snooping
FIP snooping is the correct answer because it is the FCoE feature that enables multiple VLANs to be carried over a single physical link by snooping FIP (FCoE Initialization Protocol) frames. FIP snooping builds a forwarding table that maps FCoE sessions to specific VLANs, allowing the switch to forward FCoE traffic for different VLANs on the same physical interface while maintaining isolation and security.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
NPV
Why it's wrong here
NPV is a Fibre Channel feature.
- ✗
VSANs
Why it's wrong here
VSANs are for FC, not FCoE VLANs.
- ✓
FIP snooping
Why this is correct
FIP snooping enables multiple FCoE VLANs on a link.
- ✗
Port channels
Why it's wrong here
Port channels aggregate links but don't inherently support multiple VLANs.
