A network engineer is analyzing application traffic across an enterprise WAN link between a real-time voice streaming service and a critical transactional database connection. Which two operational characteristics accurately distinguish User Datagram Protocol (UDP) from Transmission Control Protocol (TCP) in this scenario? (Select two.)
- UDP operates with a fixed 8-byte header structure and omits delivery acknowledgments, minimizing processing latency for real-time traffic.Answer
- TCP maintains stateful connection tracking using a baseline 20-byte header that incorporates sequence numbers, acknowledgment numbers, and dynamic windowing controls.Answer
- CUDP implements a dynamic window size field within its transport header to perform end-to-end flow control during periods of network congestion.
- DTCP reduces transmission overhead by bypassing header checksum verification when processing sequential bulk transactional data.
Answer
UDP provides a low-overhead, connectionless service with an 8-byte header without acknowledgments, whereas TCP provides a stateful, connection-oriented service with a 20-byte baseline header supporting sequence tracking, acknowledgments, and flow control.
The correct statements correctly identify that UDP utilizes a streamlined 8-byte header without delivery acknowledgments to minimize real-time latency, whereas TCP utilizes a 20-byte baseline header containing sequence numbers, acknowledgment numbers, and dynamic windowing to ensure connection-oriented reliability and flow control.
