CompTIA Network+ (N10-008) — Question 257

A network technician needs to ensure that all files on a company's network can be moved in a safe and protected manner without interception from someone who is not the intended recipient. Which of the following would allow the network technician to meet these requirements?

Answer options

• A. FTP
• B. TFTP
• C. SMTP
• D. SFTP

Correct answer: D

Explanation

The correct answer is D, SFTP, as it provides secure file transfer over SSH, ensuring that data is encrypted during transmission.
