NSE7 Advanced Networking and SD-WAN Practice Question
An administrator wants to use FortiExtender to provide LTE WAN connectivity. After connecting the FortiExtender to the FortiGate, the LTE interface is not showing up. What is the first troubleshooting step?
⚠ Common exam trap
The trap here is that candidates jump to software-level troubleshooting (like running diagnostic commands or checking signal strength) without first confirming the basic physical connectivity and power status of the FortiExtender.

Correct answer & explanation
✓
Verify the FortiExtender is connected to the correct port and powered on
The first troubleshooting step is to verify the physical connection and power status of the FortiExtender. If the FortiExtender is not connected to the correct port (typically a USB or PoE port) or is not powered on, the FortiGate will not detect the LTE interface at all, making any software-level checks premature.
