NSE7 Advanced Networking and SD-WAN Practice Question
A network admin is troubleshooting an SD-WAN rule that should steer VoIP traffic to a low-latency link. The rule matches traffic from the VoIP subnet to any destination and uses the 'best-quality' strategy with SLA monitoring. However, traffic is still using the other link. Which TWO checks should the admin perform? (Choose two.)

Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Ensure that the FortiGate has a default route via each SD-WAN member.
Why it's wrong here
SD-WAN rules override routing decisions; default routes are not required for SD-WAN to function.
- ✓
Check that the SD-WAN rule has a higher priority than other rules that might match the traffic.
Why this is correct
SD-WAN rules are evaluated in order; a rule with higher priority (lower number) takes precedence.
- ✗
Disable the other SD-WAN members temporarily to force traffic to the desired link.
Why it's wrong here
This is a test but not a proper troubleshooting step; it does not identify the root cause.
- ✗
Confirm that the VoIP subnet is included in the SD-WAN zone.
Why it's wrong here
SD-WAN zones are not used; SD-WAN rules use members directly or via device groups.
- ✓
Verify that the performance SLA is correctly configured and the VoIP traffic matches the SLA's server.
Why this is correct
The best-quality strategy requires the SLA to be matched to the traffic; if the SLA is not configured for the VoIP traffic's destination, the strategy may not work.
