Which of the following protocols is used by network devices to send error messages and operational information, enabling administrators to diagnose and troubleshoot issues with IP packet delivery?

ICMP

UDP is a connection-oriented protocol using a three-way handshake, which is a set of initial steps required for establishing a network connection. UDP supports error checking, flow control (managing the amount of data that is being sent), sequencing (rearranging packets that arrived out of order), and retransmission of lost packets. Example applications of UDP include the transmission of text and image data.

False

TCP is an example of a connectionless protocol. Because TCP does not support a three-way handshake while establishing a network connection, it is referred to as an unreliable or best-effort protocol. Example applications of TCP include the transmission of video and audio streaming data.

False
