NSE7 Enterprise Firewall and VDOMs Practice Question
Which of the following is a required step when enabling VDOMs on a FortiGate for the first time?
⚠ Common exam trap
Many candidates assume VDOMs can be enabled and used immediately without a reboot, similar to other features like interface configuration, but FortiGate specifically requires a reboot to activate the multi-VDOM architecture.

Correct answer & explanation
✓
Reboot the FortiGate after enabling VDOMs
When enabling VDOMs on a FortiGate for the first time, the device must be rebooted to restructure the internal data plane and control plane to support multiple virtual domains. This reboot is mandatory because the firmware transitions from a single-VDOM mode to a multi-VDOM mode, which requires reinitializing kernel structures and memory allocation for VDOM-specific resources.
