NSE7 Troubleshooting and Diagnostics Practice Question
An administrator is configuring SD-WAN with multiple members. When a rule matches, traffic is not being load-balanced as expected. Which command should the admin use to verify the SD-WAN rule selection for a specific flow?
⚠ Common exam trap
Watch out — candidates often confuse 'diagnose sys session list' (which shows session details but not SD-WAN rule selection) with the correct diagnostic command, leading them to pick Option A because they assume session information includes SD-WAN rule matching.

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
diagnose sys sdwan info
'diagnose sys sdwan info' is the FortiOS command that displays detailed SD-WAN rule selection information, including which rule matched for a specific flow and how traffic is being load-balanced across members. This command provides real-time diagnostics on SD-WAN path selection, rule IDs, and member usage, which directly addresses the administrator's need to verify rule matching and load-balancing behavior.
