Cisco 200-301 Question Answer

Why is UDP more suitable than TCP tor applications that require low latency, such as VoIP?

UDP reliably guarantees delivery of all packets and TCP drops packets under heavy load.

TCP sends an acknowledgment for every packet that is received and UDP operates without acknowledgments.

UDP uses sequencing data for packets to arrive in order, and TCP offers the capability to receive packets in random order.

TCP uses congestion control for efficient packet delivery and UDP uses flow control mechanisms for the delivery of packets.
