Quick Answer
The correct command is `diagnose sys session filter src 192.168.1.10` followed by `diagnose sys session list`. This two-step process works because the filter command sets a session-matching criterion—in this case, the source IP—without displaying output, and the subsequent `list` command then retrieves only the sessions that match that active filter. On the Fortinet NSE 7 Advanced Security NSE7 exam, this tests your ability to navigate FortiGate’s diagnostic CLI for real-time traffic analysis, a common scenario in troubleshooting policy or NAT issues. A frequent trap is forgetting that `filter` alone does not show results; you must always pair it with `list` or `clear` to apply or reset the filter. For a quick memory anchor, think “filter first, then list”—just like setting a search term before hitting enter.
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 wants to see the current sessions for a specific source IP address 192.168.1.10. Which CLI command should be used?
diagnose sys session filter src 192.168.1.10; diagnose sys session list
This is the correct way to filter and list sessions for a source IP.
get system session list src 192.168.1.10
Why wrong: This command does not exist; 'get system session' is not valid.
diagnose debug flow src-addr 192.168.1.10
Why wrong: This debugs flow, not lists sessions.
execute session list source 192.168.1.10
Why wrong: This command does not exist.

Correct answer & explanation
diagnose sys session filter src 192.168.1.10; diagnose sys session list
The 'diagnose sys session filter' command allows filtering sessions by various criteria. Setting the source filter and then using 'diag sys session list' displays matching sessions.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
diagnose sys session filter src 192.168.1.10; diagnose sys session list
Why this is correct
This is the correct way to filter and list sessions for a source IP.

This command does not exist.
Common exam traps
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Trap categories for this question
Command / output trap
This command does not exist; 'get system session' is not valid.
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.
