350-601 Storage Network Practice Question
An engineer needs to isolate storage traffic for different departments using Fibre Channel switches. Which technology should be used?
⚠ Common exam trap
Cisco often tests the distinction between zoning and VSANs, where candidates mistakenly believe that zoning alone provides full traffic isolation, but zoning only controls device communication within a single VSAN and does not isolate fabric services or management domains.
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
✓
VSAN (Virtual SAN)
VSAN (Virtual SAN) is the correct technology because it allows the engineer to create multiple isolated virtual SANs on a single physical Fibre Channel fabric. Each VSAN operates as an independent SAN with its own fabric services, security policies, and traffic isolation, enabling different departments to have dedicated storage traffic without interference.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Zoning
Why it's wrong here
Incorrect: Zoning controls access but does not provide traffic isolation.
- ✗
Trunking
Why it's wrong here
Incorrect: Trunking allows multiple VSANs on a single link.
- ✗
NPV (N-Port Virtualization)
Why it's wrong here
Incorrect: NPV is used to reduce Fibre Channel domain IDs, not isolation.
- ✓
VSAN (Virtual SAN)
Why this is correct
Correct: VSANs create separate Fibre Channel fabrics for isolation.
