Question

A network engineer is documenting the transport protocols used by applications on the corporate network. One application streams real-time voice traffic between IP phones, where minimizing delay is critical and occasional lost packets are acceptable rather than retransmitting them. Which transport protocol best fits this application's requirements?

Accepted Answer

UDP, because it is connectionless and adds minimal overhead and latency

Answer

TCP, because it guarantees delivery through acknowledgments and retransmission

Answer

TCP, because its windowing mechanism reduces jitter in voice streams

Answer

UDP, because it uses sequence numbers to reorder voice packets reliably
