350-601 Storage Network Practice Question
A storage administrator notices that a host is unable to see a LUN after zoning is configured. The zone contains the host WWPN and the target WWPN. The LUN is not masked at the storage array. What is the most likely cause?
⚠ Common exam trap
Cisco often tests the distinction between fabric-level zoning (which controls which ports can communicate) and storage-array-level LUN masking (which controls which LUNs are visible to an initiator), leading candidates to incorrectly assume zoning alone grants LUN access.
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
✓
LUN masking is not configured on the storage array.
The host cannot see the LUN because LUN masking is not configured on the storage array. Even with correct zoning (host WWPN to target WWPN), the storage array must explicitly grant access to specific LUNs for a given initiator WWPN. Without LUN masking, the target will not present the LUN to the host, regardless of zone membership.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
LUN masking is not configured on the storage array.
Why this is correct
LUN masking is required to present LUNs to specific hosts.
- ✗
The host requires NPIV to be enabled.
Why it's wrong here
NPIV is for multiple N-port IDs, not necessary here.
- ✗
The host is in a different VSAN.
Why it's wrong here
No evidence of VSAN mismatch.
- ✗
The zone is incorrectly configured.
Why it's wrong here
Zone has correct WWPNs.
