100-150 Question 55
Single answerA network administrator is troubleshooting a file transfer issue. The administrator observes that the transfer protocol being used does not establish a connection before sending data and has minimal overhead. Which protocol is most likely being used in this scenario?
- A
FTP
- B
SFTP
- C
TFTP
- D
HTTP
Show answer and explanation
Correct answer: C
Explanation
TFTP is the correct answer because it is designed as a simple, connectionless file transfer protocol using UDP (User Datagram Protocol). Unlike FTP and SFTP, TFTP does not establish a connection before transferring data, which aligns with the description of the protocol in the scenario.
- A. Incorrect.
FTP (File Transfer Protocol) is a connection-oriented protocol that requires a TCP connection to ensure reliability during file transfers. This does not match the scenario described.
- B. Incorrect.
SFTP (Secure File Transfer Protocol) is also connection-oriented and uses SSH to provide secure file transfer, making it unsuitable for the scenario involving a connectionless protocol.
- C. Correct.
TFTP (Trivial File Transfer Protocol) is a connectionless protocol that uses UDP, making it lightweight with minimal overhead. It fits the scenario described in the question.
- D. Incorrect.
HTTP (HyperText Transfer Protocol) is a connection-oriented protocol that uses TCP, typically for web page requests and data transfer, and does not match the described scenario.
