Selected Answer: A
When a session is closed by both the sender and receiver, FortiGate keeps that session in the session table for a few seconds, to allow for any out-of-order packets that might arrive after the FIN/ACK packet. Network Security Support Engineer 7.4 Study Guide 84

Selected Answer: A
