zone name ZONE_C
member pwwn 10:00:00:00:c9:29:3b:23Refer to the exhibit. A host with WWPN 10:00:00:00:c9:29:3b:23 can only see its own WWPN but not the target. What is the likely cause?
⚠ Common exam trap
Cisco often tests the distinction between 'zone not activated' and 'target missing from zone' — the trap here is that candidates assume a zone must be activated for any visibility, but in reality, a host can see its own WWPN even if the zone is inactive, as long as it has successfully logged into the fabric.
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
✓
The target is missing from the zone.
The host can see its own WWPN but not the target, which indicates that the host has successfully logged into the fabric (FLOGI accepted) and is in the correct VSAN. The most likely cause is that the target WWPN is not included in the zone that contains the host. In Fibre Channel zoning, only members within the same zone can communicate; if the target is missing from the zone, the host cannot discover or access it.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
The host is in a different VSAN.
Why it's wrong here
The command was for VSAN 1, so the host is in VSAN 1.
- ✓
The target is missing from the zone.
Why this is correct
Zone_C has no target member, so the host cannot access any storage.
- ✗
The zoneset is not the full zoneset.
Why it's wrong here
The output shows the active zoneset; it is the full set.
- ✗
The host's FLOGI is rejected.
Why it's wrong here
If the host can see its own WWPN, it has logged in successfully.
- ✗
The zone is not activated.
Why it's wrong here
Zone_C is listed under the active zoneset, so it is activated.
