NSE7 Troubleshooting and Diagnostics Practice Question
An SD-WAN rule is configured to steer traffic based on SLA metrics. The administrator notices that traffic is not using the expected member interface even though the SLA is meeting thresholds. What should the administrator check FIRST?
⚠ Common exam trap
Watch out — candidates often assume SLA compliance alone guarantees traffic will use the member, ignoring that SD-WAN rules also consider load-balancing algorithms, session stickiness, and explicit member selection in the rule configuration.

Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Run 'diagnose sys sdwan info' to verify the rule and member status
'diagnose sys sdwan info' provides a real-time view of SD-WAN rule status, member interface health, and SLA compliance. This command directly shows whether the rule is matching traffic and if the expected member is active or has been deprioritized due to implicit factors like session stickiness or load-balancing algorithm, which are not visible in the SLA thresholds alone.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Check the firewall policy to ensure SD-WAN is enabled
Why it's wrong here
SD-WAN is configured on policies, but this is a configuration check, not a diagnostic command.
- ✗
Verify the BGP configuration to ensure routes are being advertised
Why it's wrong here
BGP is not directly related to SD-WAN SLA-based steering.
- ✓
Run 'diagnose sys sdwan info' to verify the rule and member status
Why this is correct
This command shows detailed SD-WAN information.
- ✗
Restart the FortiGate to clear any stale sessions
Why it's wrong here
Restarting is disruptive and not a first step.
