The correct answer is AC.
In FortiGate, “ephemeral” sessions typically refer to sessions that are either not fully established or consist of only a single packet. Specifically:
A. A UDP session with only one packet received – This qualifies as ephemeral because there has been no return traffic (only one packet).
C. A TCP session waiting for the SYN ACK – This also qualifies as ephemeral because the session is still half-open and not fully established.
