Which the following flags are used to establish a TCP connection? (Select TWO).

PSH (Push) is used to instruct the receiver to pass buffered data to the application immediately and is not part of connection establishment.

ACK is used in the second step when the server sends a SYN-ACK back to the client, and again in the third step when the client sends a final ACK to complete the connection establishment.

SYN is sent by the client in the first step to initiate the connection, and included by the server in the SYN-ACK response, making it essential to the handshake process.

URG (Urgent) signals that certain data should be prioritized but plays no role in the TCP three-way handshake.

FIN is used to gracefully terminate an established connection, not to establish one.
