A network administrator is evaluating transport layer requirements for a real-time voice conferencing application and a critical database replication service. Which two operational characteristics accurately describe User Datagram Protocol (UDP) when compared to Transmission Control Protocol (TCP)? (Select two.)
- UDP operates as a connectionless protocol that transmits data without establishing a initial session handshake.Answer
- UDP utilizes a fixed 8-byte header overhead to minimize latency and processing burden.Answer
- CUDP guarantees segment delivery order by embedding sequence and acknowledgment numbers into its protocol header.
- DUDP dynamically manages buffer utilization across endpoints using a sliding window mechanism for flow control.
Answer
UDP is characterized by its connectionless operation without a session handshake and its compact 8-byte fixed header structure.
The statements highlighting UDP as a connectionless protocol without session handshakes and noting its fixed 8-byte header overhead are correct. UDP provides low-latency transmission by dispensing with connection setup and header complexity.
