A network engineer is selecting file transfer protocols to manage system images and configuration backups for enterprise edge routers. Which two statements accurately describe how TFTP and FTP differ in their underlying transport and operational characteristics?
- TFTP relies on connectionless UDP transport using port 69 without native user authentication, whereas FTP uses connection-oriented TCP transport and requires authentication credentials.Cevap
- BTFTP implements sliding window mechanics to maximize throughput, whereas FTP relies on lockstep stop-and-wait acknowledgements.
- FTP establishes separate TCP connections for session control commands and data transfer, whereas TFTP uses a single UDP channel for both data transmission and acknowledgements.Cevap
- DFTP establishes connectionless UDP sessions on port 21 for high-speed transfer, whereas TFTP establishes stateful TCP sessions on port 69 to guarantee packet retransmission.
Cevap
The correct statements are that TFTP relies on connectionless UDP transport on port 69 without authentication while FTP uses TCP with authentication credentials, and that FTP establishes separate control and data connections whereas TFTP uses a single UDP channel.
TFTP uses connectionless UDP on port 69 without native authentication and handles control and data over a single stream. In contrast, FTP uses connection-oriented TCP, requires user authentication, and separates control signals (TCP 21) from data transfers (TCP 20).
