CompTIA Network+ (N10-007) — Question 689

A network administrator it concerned about the management traffic between a machine and the corporate router. Which of the following protocols should the administrator use to prevent a security breach?

Answer options

• A. VNC
• B. SSH
• C. RDP
• D. SFTP

Correct answer: B

Explanation

SSH is the correct choice because it provides a secure channel over an unsecured network by encrypting the data transmitted, thus preventing unauthorized access. The other options, while useful for remote access or file transfer, do not offer the same level of security for management traffic as SSH does.
