NSE7 Enterprise Firewall and VDOMs Practice Question
A network administrator is configuring inter-VDOM routing between two VDOMs: VDOM-A and VDOM-B. The administrator creates a inter-VDOM link and adds routes pointing to the link. However, traffic from VDOM-A to VDOM-B fails. What is the most likely missing configuration?
⚠ Common exam trap
Many exam-takers assume routing alone is sufficient for inter-VDOM communication, overlooking FortiGate's requirement for explicit firewall policies to permit traffic across VDOM boundaries, similar to how policies are needed between physical interfaces.
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
✓
A firewall policy must be created in each VDOM to permit traffic across the inter-VDOM link
In FortiGate, inter-VDOM routing requires firewall policies in each VDOM to explicitly permit traffic across the inter-VDOM link. Without these policies, the FortiGate drops the traffic even if routes are correctly configured, because the inter-VDOM link behaves like a virtual interface that requires policy-based access control.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Both VDOMs must be in transparent mode
Why it's wrong here
Inter-VDOM routing works in both modes.
- ✗
The inter-VDOM link must be in the same VDOM
Why it's wrong here
Inter-VDOM links span two VDOMs.
- ✗
The management VDOM must be enabled
Why it's wrong here
Management VDOM is for central management, not required for inter-VDOM routing.
