Cyber Fundamentals Block 1 Practice Exam

Connectionless protocols are also known as _______ communications since ________ is involved.

Datagram, UDP Datagram, TCP Datagram, IP Datagram, ICMP

Correct Answer:

Datagram, UDP

Explanation:

Datagram communications describe sending data as independent packets without establishing a connection first. UDP is the transport-layer protocol that provides this connectionless, datagram-based service, so this pairing fits best. TCP is connection-oriented and creates a reliable stream rather than discrete datagrams; IP operates at the network layer and, while it routes datagrams, it isn’t the transport service described here; ICMP is for control messages, not delivering application data.
