The server health check mechanism is enabled on the USG firewall of an enterprise to detect the running status of the back-end real server (the three servers are Server A, Server B, and Server C). When the USG fails to receive the response from Server B multiple times. When the message is received, Server B will be disabled and the traffic will be distributed to other servers according to the configured policy.

In the TCP/IP protocol, the TCP protocol provides a reliable connection service, which is implemented using a 3-way handshake. First handshake: When establishing a connection, the client sends a SYN packet (SYN=J) to the server and enters the SYN_SENT state, waiting for the server to confirm; the second handshake: the server receives the SYN packet and must send an ACK packet (ACK=1) To confirm the SYN packet of the client, and also send a SYN packet (SYN=K), that is, the SYN-ACK packet, the server enters the SYN_RCVD state; the third handshake: the client receives the SYN-ACK packet of the server. Send the acknowledgement packet ACK (SYN=2 ACK=3) to the server. After the packet is sent, the client and server enter the ESTABUSHED state and complete the handshake. Regarding the three parameters in the 3-way handshake process, which one is correct?
