Which TCP states does the global setting `tcp-half-open-timer' applies to? (Choose two.)

The SYN_SENT state indicates a connection where a SYN packet has been sent but no SYN/ACK has been received, which is a classic half-open condition for which a timer is crucial to prevent resource exhaustion.

SYN & SYN/ACK are part of the initial three-way handshake; the `tcp-half-open-timer` targets the client-side SYN_SENT state and server-side SYN_RECV (not listed) states to protect against SYN floods, but not SYN/ACK as a standalone state for half-open resource management.

FIN_WAIT states occur during the graceful closure of a TCP connection and are managed by different timeout settings, not specifically the `tcp-half-open-timer` which focuses on initial connection establishment or specific post-closure scenarios.

The TIME_WAIT state, while typically occurring after connection closure, is also managed by `tcp-half-open-timer` on FortiGates to control resource usage by tracking lingering connections.
