NSE7 Enterprise Firewall and VDOMs Practice Question
A network administrator is troubleshooting a FortiGate that is not appearing in the Security Fabric topology on FortiManager. The FortiGate is reachable from FortiManager via ping. What is the most likely cause?
⚠ Common exam trap
Many exam-takers assume Layer 3 reachability (ping) implies full application-layer communication, but FortiManager requires explicit authorization before it will accept a FortiGate into the Security Fabric, even when network connectivity is perfect.

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The FortiGate is not authorized in FortiManager
For a FortiGate to appear in the Security Fabric topology on FortiManager, it must first be authorized in FortiManager. Even if the FortiGate is reachable via ping, without authorization, FortiManager will not accept its registration or include it in the topology view. This is a prerequisite step that must occur before any fabric communication can be established.
