CompTIA Server+ (SK0-005) — Question 159

A security technician generated a public/private key pair on a server. The technician needs to copy the key pair to another server on a different subnet.

Which of the following is the MOST secure method to copy the keys?

Answer options

• A. HTTP
• B. FTP
• C. SCP
• D. USB

Correct answer: C

Explanation

The most secure method to transfer the key pair is SCP, as it encrypts the data during transmission, providing confidentiality and integrity. In contrast, HTTP and FTP do not encrypt data, making them vulnerable to interception, while using USB could expose the keys to physical theft or loss.
