NSE7 Enterprise Firewall and VDOMs Practice Question
An administrator configures a VDOM on a FortiGate and assigns two interfaces (port1, port2) to it. The administrator wants to route traffic between two different subnets within the same VDOM. Which configuration is required?
⚠ Common exam trap
Watch out — candidates often confuse intra-VDOM routing (within the same VDOM) with inter-VDOM routing (between VDOMs) and incorrectly assume that a VDOM link or inter-VDOM routing must be enabled, when in fact standard routing is sufficient.

Correct answer & explanation
✓
Configure static or dynamic routing
Routing between two subnets within the same VDOM is standard intra-VDOM routing. Since both interfaces (port1, port2) belong to the same VDOM, no inter-VDOM constructs are needed; the FortiGate simply requires a route (static or dynamic) to forward packets between the subnets. A firewall policy allowing the traffic is also necessary, but the question specifically asks for the routing configuration.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Configure a VDOM link
Why it's wrong here
VDOM links connect VDOMs, not internal routing within a VDOM.
- ✗
Create a policy with inter-VDOM link
Why it's wrong here
Inter-VDOM links are for connecting VDOMs, not for routing within a VDOM.
- ✗
Enable inter-VDOM routing
Why it's wrong here
Inter-VDOM routing is used between different VDOMs, not within the same VDOM.
- ✓
Configure static or dynamic routing
Why this is correct
Standard routing within the VDOM is sufficient to route between subnets on different interfaces.
