200-301 Question 397
Single answerA network administrator needs to transfer a configuration file from a router to a server for backup purposes. The network has both TFTP and FTP servers available. Which protocol should the administrator use if security and file integrity are critical considerations?
- A
TFTP, because it is faster and simpler for file transfers
- B
TFTP, because it supports authentication and encryption
- C
FTP, because it supports authentication and file integrity checks
- D
FTP, because it operates over UDP and avoids delays
Show answer and explanation
Correct answer: C
Explanation
When choosing between TFTP and FTP for file transfers in scenarios where security and file integrity are critical, FTP is the appropriate choice. FTP supports authentication and mechanisms to ensure file integrity, while TFTP is a simpler protocol that lacks these security features. Although TFTP may be faster due to its lightweight design, it sacrifices security and reliability, making it unsuitable for this use case.
- A. Incorrect.
TFTP is indeed faster and simpler than FTP, but it does not offer security features like authentication or encryption, making it unsuitable when security and file integrity are critical.
- B. Incorrect.
TFTP does not support authentication or encryption. It is a lightweight protocol designed for simplicity and speed, not for secure or reliable transfers.
- C. Correct.
FTP supports authentication (via usernames and passwords) and can use mechanisms like checksum verification to ensure file integrity, making it suitable for scenarios where security and file integrity are important.
- D. Incorrect.
FTP does not operate over UDP; it uses TCP, which provides reliable data transfer with error-checking mechanisms.
