Question #: 43
Topic #: 2
Which transport layer protocol provides best-effort delivery service with no acknowledgment receipt required?

Suggested Answer: E Vote an answer

UDP provides a connectionless datagram service that offers best-effort delivery, which means that UDP does not guarantee delivery or verify sequencing for any datagrams. A source host that needs reliable communication must use either TCP or a program that provides its own sequencing and acknowledgment services.
