Exam N10-008 topic 1 question 332 discussion

A. RST (Reset) is the most likely response that the client would receive if it is trying to connect to the wrong TCP port. TCP (Transmission Control Protocol) is a connection-oriented protocol, which means that a connection needs to be established between the client and the server before data can be exchanged. During the connection establishment process, the client sends a SYN (Synchronize) packet to the server, and the server responds with a SYN-ACK (Synchronize-Acknowledge) packet. If the client is trying to connect to the wrong TCP port, the server will not respond with a SYN-ACK packet, and instead, it will send a RST packet to terminate the connection attempt.

Since there's no comments, good ol ChatGPT helped me A RST response is generated by the server when a client attempts to connect to a TCP port that is not open. The RST message informs the client that the port is not available, and the client should reset its connection. The RST response is generated by the server to immediately terminate the connection attempt and prevent the client from wasting resources attempting to connect to a port that will not respond.

A. RST (Reset) Explanation: RST (Reset): When a client attempts to connect to a TCP port that is not open or is not accepting connections, the server typically responds with a TCP RST packet. This indicates that the port is closed or not listening, and the connection request is rejected.
