NSE7 Advanced Networking and SD-WAN Practice Question
An administrator wants to integrate a FortiExtender with a FortiGate to provide WAN connectivity. Which interface type is used on the FortiGate to connect to the FortiExtender?
⚠ Common exam trap
Many candidates confuse the 'wan' interface type with a generic physical port (like port1 or port2) and assume any interface can be used, but FortiGate specifically requires the 'wan' interface type to enable FortiExtender integration and its associated management features.

Correct answer & explanation
✓
wan
The FortiGate uses a dedicated 'wan' interface type to connect to a FortiExtender, as this interface is specifically designed to manage the cellular or broadband WAN link provided by the extender. The FortiExtender appears as a WAN-facing device, and the 'wan' interface type allows the FortiGate to apply SD-WAN rules, load balancing, and failover policies directly to that connection.
