NSE7 Enterprise Firewall and VDOMs Practice Question
An administrator creates a new VDOM and assigns interfaces. The VDOM is intended to operate in transparent mode. Which additional step is required?
⚠ Common exam trap
It's easy for candidates to assume VDOMs default to transparent mode or that disabling NAT alone is sufficient, but FortiGate requires an explicit mode change via 'config system settings' to enable transparent operation.

Correct answer & explanation
✓
Set the VDOM's mode to transparent under config system settings
A VDOM does not default to transparent mode; it must be explicitly configured. The command 'config system settings' with 'set vdom-type transparent' changes the VDOM's operational mode from the default NAT/route mode to transparent mode, which is required for the VDOM to function as a Layer 2 bridge.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Set the VDOM's mode to transparent under config system settings
Why this is correct
The VDOM must be explicitly set to transparent mode.
- ✗
Disable NAT on all policies
Why it's wrong here
NAT is not used in transparent mode but not a step.
- ✗
Configure a management IP for the VDOM
Why it's wrong here
Management IP is optional and not required for transparent mode.
- ✗
No additional steps; VDOMs default to transparent mode
Why it's wrong here
Default mode is NAT/route.
