NSE7 Enterprise Firewall and VDOMs Practice Question
An administrator runs 'diagnose debug vd case <vdom_name>' and receives the error 'VDOM not found'. The VDOM exists and is configured. What is the most likely cause?
⚠ Common exam trap
It's easy for candidates to assume the error means the VDOM does not exist or is misconfigured, overlooking FortiOS's strict case sensitivity for VDOM names in CLI commands.

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The VDOM name is misspelled or has incorrect case
The 'diagnose debug vd case' command is case-sensitive and expects the exact VDOM name as configured. Even if the VDOM exists, a mismatch in letter case (e.g., typing 'VDOM1' instead of 'vdom1') will cause the 'VDOM not found' error because the command performs a literal string comparison without case normalization.
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 VDOM is a traffic VDOM and requires a different command
Why it's wrong here
The command works for all VDOM types.
- ✗
The VDOM is administratively disabled
Why it's wrong here
A disabled VDOM would show in the configuration but not be operational; the command would still find it.
- ✗
The administrator is in the wrong VDOM context
Why it's wrong here
The command is not context-sensitive; it should still find the VDOM by name.
- ✓
The VDOM name is misspelled or has incorrect case
Why this is correct
The debug command is case-sensitive and requires exact spelling.
