NSE7 Troubleshooting and Diagnostics Practice Question

An administrator needs to check the health of an SD-WAN link by viewing the last SLA probe results. Which command should be used?

⚠ Common exam trap

It's easy for candidates to confuse the SD-WAN SLA log command (`diagnose sys virtual-wan-link sla-log`) with the health-check command, or mistakenly think debug commands show historical results, when in fact only the health-check command provides the last probe results.

Answer choices

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

diagnose sys virtual-wan-link health-check

The command `diagnose sys virtual-wan-link health-check` displays the last SLA probe results for SD-WAN links, including metrics like latency, jitter, and packet loss. This command is specifically designed for FortiGate SD-WAN (formerly virtual-wan-link) to verify real-time health-check status, which is essential for troubleshooting link performance.

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

  • diagnose sys sdwan sla-log

    Why it's wrong here

    This shows SLA log history, not current health.

  • get system interface physical

    Why it's wrong here

    This shows physical interface status, not SD-WAN health check results.

  • diagnose debug application sdwan -1

    Why it's wrong here

    This enables debug output, not health check results.

  • diagnose sys virtual-wan-link health-check

    Why this is correct

    This command shows the results of SD-WAN health checks including SLA status.
