NSE7 Advanced Networking and SD-WAN Practice Question
An administrator wants to integrate a FortiExtender into an existing SD-WAN deployment. Which TWO steps are required for proper integration?
⚠ Common exam trap
Watch out — candidates often assume the FortiExtender requires a separate VDOM or NAT configuration, when in fact it simply needs authorization and SD-WAN membership to function as a standard WAN interface within the existing SD-WAN topology.

Correct answer & explanation
✓
Authorize the FortiExtender on the FortiGate
The FortiExtender must first be authorized on the FortiGate to establish a secure management and data plane connection. Once authorized, it must be added as an SD-WAN member interface so that SD-WAN rules and load-balancing algorithms can be applied to traffic traversing the FortiExtender's cellular or LTE link.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Disable all other WAN interfaces
Why it's wrong here
Not required; other interfaces can coexist.
- ✓
Authorize the FortiExtender on the FortiGate
Why this is correct
Authorization is needed for management and integration.
- ✗
Enable NAT on the FortiExtender interface
Why it's wrong here
NAT configuration is separate and not mandatory for integration.
- ✗
Configure a separate VDOM for the FortiExtender
Why it's wrong here
Not required; it can be in the same VDOM.
- ✓
Configure the FortiExtender as an SD-WAN member
Why this is correct
It must be added as a member so SD-WAN rules can use it.
