350-601 Storage Network Practice Question
A Fibre Channel fabric has multiple initiators and targets. The engineer wants to ensure that only specific hosts can access specific storage volumes. Which zoning practice is most secure?
⚠ Common exam trap
Cisco often tests the misconception that VSANs alone provide sufficient security, but the trap is that VSANs isolate traffic at the fabric level, not at the device level, so zoning is still required within each VSAN to control which initiators can access which targets.

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Single-initiator zoning with WWPNs
Single-initiator zoning with WWPNs is the most secure practice because it creates a one-to-one mapping between a single initiator and its target(s) using the globally unique World Wide Port Name. This eliminates any possibility of unauthorized access or interference from other initiators, as each zone contains exactly one initiator, preventing any form of 'spoofing' or 'zoning overlap' that could allow a rogue host to access storage volumes it should not see.
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 by storage array aliases
Why it's wrong here
Incorrect: Aliases simplify management but do not increase security.
- ✓
Single-initiator zoning with WWPNs
Why this is correct
Correct: Single-initiator zoning is the most secure practice.
- ✗
Using VSANs instead of zones
Why it's wrong here
Incorrect: VSANs isolate at fabric level, not per device.
- ✗
Soft zoning with domain/port IDs
Why it's wrong here
Incorrect: Soft zoning allows RSCN flooding and is less secure than hard zoning.
