Which transport layer protocol provides best-effort delivery service with no acknowledgment
receipt required?
A.
HTTP
B.
IP
C.
TCP
D.
Telnet
E.
UDP
Explanation:
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.
E – UDP
Explanation; Transport layer protocols are TCP and UDP. Because, TCP delivers only while ackonwledging the sending and receiving, the UDP should be the right answer.
