100-150 Question 52
Single answerA network administrator is troubleshooting an issue where a file transfer between two systems is failing. The administrator notices that the protocol being used does not establish a connection before transferring data, and there is no error recovery. Which protocol is most likely being used for this transfer?
- A
FTP
- B
SFTP
- C
TFTP
- D
HTTP
Show answer and explanation
Correct answer: C
Explanation
TFTP is a connectionless protocol, meaning it does not establish a session before sending data. This makes it lightweight but unreliable, as it lacks error recovery mechanisms. This is in contrast to other protocols like FTP or SFTP, which are connection-oriented and ensure reliable file transfers.
- A. Incorrect.
FTP (File Transfer Protocol) is a connection-oriented protocol that establishes a session before transferring files and provides error recovery mechanisms.
- B. Incorrect.
SFTP (Secure File Transfer Protocol) is also connection-oriented and uses encryption to securely transfer files, ensuring reliability and error recovery.
- C. Correct.
TFTP (Trivial File Transfer Protocol) is a connectionless protocol that does not establish a session before transferring data. It does not include error recovery mechanisms, making it less reliable for file transfers.
- D. Incorrect.
HTTP (Hypertext Transfer Protocol) is a connection-oriented protocol used for transferring web content, not typically used for file transfers in this context.
