How do TCP and UDP differ in the way that they establish a connection (CCNA 200-301)
How do TCP and UDP differ in the way that they establish a connection between two endpoints?
A) TCP uses the three-way handshake, and UDP does not guarantee message delivery.
B) TCP uses synchronization packets, and UDP uses acknowledgment packets.
C) UDP provides reliable message transfer, and TCP is a connectionless protocol.
D) UDP uses SYN, SYN ACK, and FIN bits in the frame header while TCP uses SYN, SYN ACK, and ACK bits.
Solution
Correct answer: A) TCP uses the three-way handshake, and UDP does not guarantee message delivery.
TCP (Transmission Control Protocol) uses a three-way handshake (SYN, SYN-ACK, ACK) to establish a connection between two endpoints. This process ensures reliable communication and establishes a full-duplex connection before data exchange begins.
UDP (User Datagram Protocol) is connectionless and does not have a formal connection establishment phase like TCP. It also does not guarantee message delivery, and there is no acknowledgment mechanism. UDP is considered a "best-effort" protocol, suitable for applications where some packet loss is acceptable, such as real-time streaming or online gaming.
