NSE7 Enterprise Firewall and VDOMs Practice Question
A FortiGate in transparent mode is deployed between a router and a switch. The administrator needs to apply a deep inspection profile to HTTP traffic. What is the correct configuration for the interfaces?
⚠ Common exam trap
Candidates often assume transparent mode cannot perform deep inspection because it lacks routed interfaces, but FortiGate supports full UTM inspection in transparent mode via the management IP and policy-based profiles.

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
✓
Configure a management IP on the VDOM and apply the inspection profile to the policy
In transparent mode, FortiGate acts as a Layer 2 bridge, so interfaces do not require IP addresses. Deep inspection of HTTP traffic is applied via a firewall policy that references a deep inspection profile, and a management IP must be configured on the VDOM to allow the FortiGate to participate in management traffic (e.g., DNS, NTP, or proxy operations). Option A correctly identifies that the management IP is set on the VDOM and the inspection profile is applied to the policy.
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 management IP on the VDOM and apply the inspection profile to the policy
Why this is correct
The VDOM management IP provides connectivity; policies inspect traffic on the bridge.
- ✗
Place both interfaces in the same VDOM and enable DHCP
Why it's wrong here
DHCP is separate from inspection.
- ✗
Switch to NAT mode to enable deep inspection
Why it's wrong here
Transparent mode supports deep inspection with proper configuration.
- ✗
Assign IPs to both interfaces and create a policy from LAN to WAN
Why it's wrong here
Transparent mode interfaces do not have IPs.
