The correct answer is to use the `diagnose sys session filter dport 443` command followed by `diagnose sys session list` to inspect the traffic flow. These two debug commands work together to isolate how the FortiGate is handling application-based SD-WAN traffic: the filter narrows the session table to the relevant port (HTTPS), and the list command displays the actual session details, including which SD-WAN member the traffic was steered to and why. On the Fortinet NSE 7 Advanced Security NSE7 exam, this scenario tests your ability to move beyond configuration checks and into real-time session diagnosis when an SD-WAN rule fails to steer traffic as expected, even when SLA targets appear correct. A common trap is to jump to `diagnose sys sdwan info`, which shows overall SLA status but not per-rule session steering decisions, or to use invalid commands like `diagnose sys sdwan rule`. Remember the memory tip: “Filter first, then list—don’t guess, debug the session.”
NSE7 Troubleshooting and Diagnostics Practice Question
This NSE7 practice question tests your understanding of troubleshooting and diagnostics. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
An administrator notices that an application-based SD-WAN rule is not steering traffic as expected. The SLA targets are configured correctly. Which TWO debug commands should the administrator use to diagnose the issue? (Choose two.)
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
Options A and C are correct. 'diagnose sys sdwan info' shows SD-WAN configuration and SLA status. 'diagnose sys session list' with filters shows the session details including SD-WAN member selection. Option B is invalid, D shows overall status but not per-rule, E is unrelated.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
KKey Concepts to Remember
Read the scenario before looking for a memorised answer.
Find the constraint that changes the correct option.
Eliminate answers that are true in general but not in this case.
Use explanations to understand the rule behind the answer.
TExam Day Tips
→Underline the problem statement mentally.
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A practitioner preparing for the NSE7 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.

These questions test the same concept from different angles. Work through them to make sure you can recognise it however the exam phrases it.
Variation 1. 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?
medium
A.Check the firewall policy to ensure SD-WAN is enabled
B.Verify the BGP configuration to ensure routes are being advertised
✓ C.Run 'diagnose sys sdwan info' to verify the rule and member status
D.Restart the FortiGate to clear any stale sessions
Why C: Option A is correct. The 'diagnose sys sdwan info' command provides real-time information about SD-WAN rules, member status, SLA performance, and route selection. It is the first step to troubleshoot why traffic is not following the expected path.
