CompTIA Network+ (N10-009) — Question 331

Which of the following protocol ports should be used to securely transfer a file?

Answer options

• A. 22
• B. 69
• C. 80
• D. 3389

Correct answer: A

Explanation

Port 22 is used by protocols such as SFTP and SCP, which provide secure file transfer capabilities. Ports 69 and 80 are used for TFTP and HTTP, respectively, neither of which offer secure transfers. Port 3389 is used for Remote Desktop Protocol (RDP), which is unrelated to file transfer.
