What is the difference regarding reliability and communication type (CCNA 200-301)
What is the difference regarding reliability and communication type between TCP and UDP?
A) TCP is reliable and is a connectionless protocol; UDP is not reliable and is a connection-oriented protocol.
B) TCP is not reliable and is a connectionless protocol; UDP is reliable and is a connection-oriented protocol.
C) TCP is not reliable and is a connection-oriented protocol; UDP is reliable and is a connectionless protocol.
D) TCP is reliable and is a connection-oriented protocol; UDP is not reliable and is a connectionless protocol.
Solution
Correct answer: D) TCP is reliable and is a connection-oriented protocol; UDP is not reliable and is a connectionless protocol.
TCP (Transmission Control Protocol) is a reliable protocol that provides connection-oriented communication. It ensures the reliable delivery of data by using acknowledgment, sequencing, and retransmission mechanisms.
UDP (User Datagram Protocol) is not reliable and is a connectionless protocol. It does not provide acknowledgment, sequencing, or retransmission mechanisms. UDP simply sends packets to the receiver without establishing a connection or ensuring delivery.
