200-301 Question 395
Select 3A network administrator is tasked with backing up the configuration of multiple routers in a network. The administrator considers using TFTP or FTP for this purpose. Which of the following statements correctly describe the capabilities and functions of TFTP and FTP in this scenario?
- A
TFTP is a lightweight protocol that does not require authentication for file transfers.
- B
FTP supports encryption for secure file transfers over the network.
- C
TFTP operates over UDP, which makes it faster but less reliable than FTP.
- D
FTP uses TCP, ensuring reliable data transfer with error correction mechanisms.
- E
TFTP is preferred for transferring large files due to its speed and reliability.
Show answer and explanation
Correct answers: A, C, D
Explanation
In networking, TFTP is often used for simple file transfers like configuration backups because it is lightweight and fast but lacks reliability and security features. FTP, on the other hand, is a more robust protocol with error correction mechanisms, making it suitable for reliable file transfers. However, FTP does not natively support encryption, so additional measures are required for secure transfers.
- A. Correct.
TFTP is indeed a lightweight protocol that does not require authentication, making it simple to use but less secure.
- B. Incorrect.
FTP does not natively support encryption; it requires additional mechanisms like FTPS or SFTP for secure file transfers.
- C. Correct.
TFTP uses UDP, which is connectionless and faster but less reliable due to the lack of error correction.
- D. Correct.
FTP uses TCP, which provides reliable data transfer with error detection and correction mechanisms.
- E. Incorrect.
TFTP is not ideal for transferring large files due to its lack of error correction, which can result in data loss or corruption.
