What are three characteristics of the TCP protocol? (Choose three.)
The correct answer is B. The connection is established before data is transmitted. C. It ensures that all data is transmitted and received by the remote device. F. It uses separate SYN and ACK messages to establish a connection.. TCP is a connection-oriented, reliable transport protocol that establishes a session before data exchange, guarantees delivery, and manages retransmissions.
Question
What are three characteristics of the TCP protocol? (Choose three.)
Options
- AIt uses a single SYN-ACK message to establish a connection.
- BThe connection is established before data is transmitted.
- CIt ensures that all data is transmitted and received by the remote device.
- DIt supports significantly higher transmission speeds than UDP.
- EIt requires applications to determine when data packets must be retransmitted.
- FIt uses separate SYN and ACK messages to establish a connection.

Why each option
TCP is a connection-oriented, reliable transport protocol that establishes a session before data exchange, guarantees delivery, and manages retransmissions.
TCP uses a three-way handshake (SYN, SYN-ACK, ACK), not a single SYN-ACK message, to establish a connection.
TCP is connection-oriented; it uses a three-way handshake (SYN, SYN-ACK, ACK) to establish a connection and synchronize sequence numbers before any application data is sent.
TCP provides reliable data transfer through mechanisms like sequence numbers, acknowledgements, flow control, and retransmission timers, ensuring that all data segments arrive at the destination and are reassembled correctly.
UDP is typically faster than TCP because it lacks the overhead of reliability, flow control, and connection establishment; TCP's overhead for reliability often leads to lower effective transmission speeds.
TCP itself handles retransmissions through its built-in reliability mechanisms (acknowledgements and timeouts), relieving applications of this responsibility.
The TCP three-way handshake involves three distinct messages: a SYN from the client, a SYN-ACK from the server, and a final ACK from the client to establish the connection.
