FortiManager ADOM Configuration for Independent VDOM Management
A FortiGate administrator is planning to deploy VDOMs to separate customer traffic. The administrator wants to use FortiManager for centralized management. Which TWO prerequisites must be met before the VDOMs can be managed from FortiManager?
⚠ Common exam trap
Test-takers frequently confuse inter-VDOM routing (a Layer 3 forwarding feature) with the management-plane requirement of ADOM assignment, leading candidates to incorrectly select Option A as a prerequisite for centralized management.
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 FortiGate must be assigned to an ADOM
FortiManager uses ADOMs (Administrative Domains) to logically group managed devices, and a FortiGate must be assigned to an ADOM before its VDOMs can be managed. Option D is correct because the FortiGate must be added to the FortiManager device list (via model or managed registration) to establish communication and allow policy/object provisioning to its VDOMs.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Inter-VDOM routing must be enabled
Why it's wrong here
Not a prerequisite for management.
- ✗
FortiAnalyzer must be registered with FortiManager
Why it's wrong here
FortiAnalyzer is separate; not required for VDOM management.
- ✓
The FortiGate must be assigned to an ADOM
Why this is correct
ADOM assignment organizes and isolates management.
- ✓
The FortiGate must be added to the FortiManager device list
Why this is correct
Necessary for communication and management.
- ✗
All VDOMs must be in the same ADOM
Why it's wrong here
VDOMs can be in different ADOMs if needed.

Same concept, more angles
1 more way this is tested on NSE7
These questions test the same concept from different angles. Work through them to make sure you can recognise it however the exam phrases it.
Variation 1. A FortiGate has two VDOMs: Root and CustomerA. The administrator wants to manage the CustomerA VDOM from FortiManager. What must be configured on FortiManager to allow management of the CustomerA VDOM?
medium- A.Configure an automation stitch on FortiManager
- B.Add the FortiGate to the global ADOM
- C.Enable VDOM management on FortiGate
- ✓ D.Add the FortiGate's VDOM to an ADOM
Why D: FortiManager uses Administrative Domains (ADOMs) to logically group and manage VDOMs. To manage the CustomerA VDOM, the administrator must add that specific VDOM to an ADOM on FortiManager, which then allows FortiManager to push policies, objects, and configuration to that VDOM. Without this mapping, FortiManager cannot target the VDOM for management, even if the FortiGate itself is registered.
