Suggested answer: C

Explanation:

Session Table Overview:

The session table in FortiOS tracks all active and pending sessions. It includes details like the type of session (TCP, UDP, etc.), status, and statistics.

Interpreting the Exhibit:

The exhibit from the diagnose sys session stat command shows detailed session statistics.

The specific value indicating '166 TCP sessions waiting to complete the three-way handshake' reflects the number of sessions that have initiated but not yet completed the TCP three-way handshake process (SYN, SYN-ACK, ACK).
