NSE7 Troubleshooting and Diagnostics Practice Question
An administrator is troubleshooting why a FortiGate is not applying the expected application control profile to traffic from a specific subnet. The administrator wants to verify which application signature is matching a live session in real time. Which CLI command should be used to display the application name and category for active sessions?
⚠ Common exam trap
The trap here is assuming that any diagnose debug command will show application identification, when only session listing commands provide that level of detail.
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 session list
The administrator needs to see the application name and category for active sessions. The diagnose sys session list command provides detailed session information, including application identification when application control is enabled. This allows real-time verification of which signature is matching, confirming whether the correct application control profile is applied to the subnet's traffic.
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 session filter clear
Why it's wrong here
This command clears any session filters that were previously set. It does not display session information. It is useful when you want to reset filters before applying new ones, but it does not help in identifying which application is matching a session.
- ✗
diagnose firewall iprope list
Why it's wrong here
This command shows the IP rope configuration, which controls packet flow through the firewall. It does not provide information about application identification or session details. It is used to verify policy routing and flow order, not to inspect application signatures on active sessions.
- ✓
diagnose sys session list
Why this is correct
This command lists all active sessions and includes the application name and category if application control is inspecting the session. It provides real-time visibility into which application signature matched, allowing the administrator to confirm whether the correct profile is applied. It is the standard tool for session-level troubleshooting on FortiGate.
- ✗
diagnose debug application ipsmonitor -1
Why it's wrong here
This command enables debug output for the IPS monitor daemon, which manages IPS engine processes. It does not display per-session application identification details. While it can help diagnose IPS engine restarts, it does not show which application signature matched a live session, so it is not suitable for this scenario.
