Network FundamentalsDifficulty 2/5
A network engineer captures traffic and sees a three-way handshake before data transfer. Which transport protocol and characteristic does this indicate?
- AICMP; error reporting
- BUDP; flow control
- CUDP; connectionless delivery
- DTCP; connection-oriented, reliable delivery
Show answer and rationale
Correct: D. The SYN, SYN-ACK, ACK handshake establishes a TCP connection. TCP provides reliability, ordering and flow control; UDP has no handshake.
- C — UDP does not perform a handshake.
- A — ICMP is a network-layer control protocol, not transport.
- B — UDP has no flow control.
