200-301 Question 396
Single answerA network administrator needs to back up the configuration files of several routers to a centralized server. The administrator is deciding between TFTP and FTP for this task. Which protocol should the administrator choose, and why?
- A
TFTP, because it is lightweight and does not require authentication.
- B
TFTP, because it provides secure encryption for file transfers.
- C
FTP, because it is faster and does not require a connection-oriented protocol.
- D
FTP, because it supports authentication and more reliable file transfers.
Show answer and explanation
Correct answer: D
Explanation
For backing up critical configuration files, FTP is the better choice because it supports authentication, ensuring only authorized users can access the files. Additionally, FTP uses TCP, which provides reliable, connection-oriented transfers, reducing the risk of file corruption or loss during transmission. TFTP, while lightweight and faster, lacks these reliability and security features, making it unsuitable for such sensitive tasks.
- A. Incorrect.
TFTP is lightweight and does not require authentication, but this makes it less secure and less reliable for critical tasks like backing up configuration files.
- B. Incorrect.
TFTP does not provide encryption or security features, making this incorrect.
- C. Incorrect.
FTP is not faster than TFTP; in fact, TFTP is typically faster due to its simplicity. However, FTP uses a connection-oriented protocol (TCP) for increased reliability, which is important for configuration backups.
- D. Correct.
FTP supports authentication and uses a connection-oriented protocol (TCP), making it more reliable and secure for tasks like backing up router configuration files.
