What are three characteristics of UDP? (Choose three.)

UDP is generally faster than TCP because it lacks the overhead associated with connection establishment, acknowledgments, retransmissions, and flow control mechanisms.

UDP, along with TCP, is a protocol that operates at the Transport Layer (Layer 4) of the OSI model, providing host-to-host communication.

UDP is a connectionless protocol, meaning it does not establish a formal connection before sending data, unlike TCP which is connection-oriented.

UDP provides a best-effort delivery service, meaning it sends data without guarantees of delivery, order, or duplication, relying on higher layers for any required reliability.

UDP is less reliable than TCP because it lacks built-in mechanisms for error checking, acknowledgments, retransmissions, and sequencing that TCP uses to ensure reliable data transfer.
