350-601 Storage Network Practice Question
Which feature allows a single Fibre Channel port to log in with multiple N-port IDs, enabling a host to connect to multiple targets through one port?
⚠ Common exam trap
Cisco often tests NPIV vs. NPV, and the trap here is confusing NPIV (which virtualizes N-port IDs on a host) with NPV (which virtualizes N-port IDs on a switch to reduce domain IDs in a fabric).

Correct answer & explanation
✓
NPIV
NPIV (N_Port ID Virtualization) allows a single Fibre Channel N_Port to register multiple N_Port IDs (FCIDs) with the fabric. This enables a host with one physical port to appear as multiple virtual initiators, each connecting to different targets, which is essential for virtualized environments like VMware ESXi with multiple VMs requiring separate FC connections.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
FCoE
Why it's wrong here
FCoE encapsulates FC over Ethernet.
- ✗
VSAN
Why it's wrong here
VSANs are virtual SANs for isolation.
- ✓
NPIV
Why this is correct
NPIV enables multiple N-port IDs per physical port.
- ✗
NPV
Why it's wrong here
NPV is for proxy login on a switch.
