Quick Answer
The answer is the `diagnose sys virtual-wan-link health-check` command. This is the correct choice because it directly queries the FortiGate’s real-time SD-WAN health check engine, displaying the last SLA probe results for each member link, including latency, jitter, packet loss, and current status. On the Fortinet NSE 7 Advanced Security NSE7 exam, this command tests your ability to verify SD-WAN link performance and troubleshoot SLA compliance, often appearing in scenario-based questions where an administrator must confirm whether a link meets configured thresholds. A common trap is confusing this with `diagnose sys virtual-wan-link member`, which shows interface membership but not probe results, or with `get router info routing-table`, which shows routing decisions but not health data. Remember the keyword “health-check” in the command name—it explicitly targets the probe outcome, not the link configuration. A useful memory tip: think of “health-check” as the doctor’s report for each SD-WAN link, giving you the last vital signs from the SLA probes.
This NSE7 practice question tests your understanding of troubleshooting and diagnostics. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. 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 needs to check the health of an SD-WAN link by viewing the last SLA probe results. Which command should be used?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "which command"
Why it matters: Tests specific CLI syntax. Recall the exact command and its required context — near-synonyms and partial matches are common distractors.
diagnose sys sdwan sla-log
Why wrong: This shows SLA log history, not current health.
get system interface physical
Why wrong: This shows physical interface status, not SD-WAN health check results.
diagnose debug application sdwan -1
Why wrong: This enables debug output, not health check results.
diagnose sys virtual-wan-link health-check
This command shows the results of SD-WAN health checks including SLA status.

Correct answer & explanation
diagnose sys virtual-wan-link health-check
Option A is correct. 'diagnose sys virtual-wan-link health-check' displays current health check status.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis

Trap categories for this question
Command / output trap
This shows SLA log history, not current health.
Detailed technical explanation
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.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
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.
