NSE7 Enterprise Firewall and VDOMs Practice Question
An admin runs 'diagnose sys session filter dport 443' and sees the following output: proto=6 proto_state=01 duration=3600 expire=3599 What does this indicate?
⚠ Common exam trap
Candidates often confuse `proto_state=01` with a blocking state or a handshake-in-progress state, when in fact it specifically indicates an established TCP connection in Fortinet's session table.
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
✓
The session is established and has been active for 1 hour
The output shows `proto=6` (TCP), `proto_state=01` (ESTABLISHED in Fortinet's session table), `duration=3600` seconds (1 hour), and `expire=3599` seconds (remaining lifetime). This combination indicates a fully established TCP session that has been active for one hour and is still valid, not blocked or in a transitional state.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
The session is being blocked by a firewall policy
Why it's wrong here
If blocked, the session would not appear in the session table.
- ✗
The session is in SYN_SENT state, waiting for a reply
Why it's wrong here
State '01' is established, not SYN_SENT (which would be '02').
- ✓
The session is established and has been active for 1 hour
Why this is correct
State '01' means established; duration is 3600 seconds = 1 hour.
- ✗
The session is in TIME_WAIT state after a FIN
Why it's wrong here
TIME_WAIT would be state '04'.
