NSE7 Enterprise Firewall and VDOMs Practice Question
In a multi-VDOM deployment, what is the purpose of inter-VDOM routing?
⚠ Common exam trap
Watch out — candidates often assume inter-VDOM routing is automatic or purely a routing function, but Fortinet requires explicit firewall policies to permit traffic between VDOMs, making it a security-controlled feature rather than a simple routing path.

Correct answer & explanation
✓
To allow traffic to pass between different VDOMs via firewall policies
Inter-VDOM routing allows traffic to be forwarded between different VDOMs on the same FortiGate unit. This is achieved by configuring inter-VDOM links (IVL) or using VDOM peering, and then applying firewall policies to control and secure the traffic flow between VDOMs. Option C correctly identifies that firewall policies are the mechanism used to permit or deny inter-VDOM traffic.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
To route traffic between the management VDOM and data VDOMs
Why it's wrong here
Management VDOM is separate and typically not routed.
- ✗
To provide redundancy for VDOMs in an HA setup
Why it's wrong here
HA is separate from inter-VDOM routing.
- ✓
To allow traffic to pass between different VDOMs via firewall policies
Why this is correct
Inter-VDOM routing uses VDOM links and policies.
- ✗
To connect VDOMs to external routers
Why it's wrong here
External routing is done through physical interfaces.
