350-601 Storage Network Practice Question
A data center deployment uses NPV mode on a Cisco MDS switch to connect to a core Fibre Channel switch. After configuration, the NPV switch does not register with the core. What is the most likely cause?
⚠ Common exam trap
Cisco often tests the distinction between NPV and NPIV, trapping candidates who confuse the two or assume that enabling NPV on both sides is required.
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
✓
NPIV is not enabled on the core switch.
NPV (N_Port Virtualization) mode requires NPIV (N_Port ID Virtualization) to be enabled on the core Fibre Channel switch. NPIV allows a single physical N_Port to register multiple FCIDs (Fibre Channel IDs) for multiple virtual initiators behind the NPV switch. Without NPIV on the core, the NPV switch cannot complete the FLOGI (Fabric Login) process and will not register with the fabric.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Fibre Channel ports are in trunk mode.
Why it's wrong here
Trunking is allowed.
- ✗
The core switch has NPV mode enabled.
Why it's wrong here
Core should not be NPV.
- ✓
NPIV is not enabled on the core switch.
Why this is correct
Core must have NPIV enabled for NPV.
- ✗
The NPV switch has an incorrect domain ID.
Why it's wrong here
NPV does not use domain IDs.
