Question

How do you establish a TCP session?

a. Through connectionless communication.
b. By sending a SYN-ACK handshake.
c. Using UDP handshake packets.
d. Establishing a direct link without handshakes.

Answer 1

To establish a TCP session, a SYN-ACK handshake is used.

Step-by-step explanation:

To establish a TCP session, a SYN-ACK handshake is used. When a client wants to establish a connection with a server, it sends a SYN (synchronize) packet to the server. The server then responds with a SYN-ACK (synchronize-acknowledge) packet, indicating its readiness to establish a connection. Finally, the client sends an ACK (acknowledge) packet to the server, completing the three-way handshake and establishing the TCP session.
