CompTIA Network+ (N10-009) — Question 479

Which of the following would a network administrator most likely use to securely manage a network device on a closed network?

Answer options

• A. Bastion host
• B. Remote desktop
• C. SSH
• D. Split-tunnel VPN

Correct answer: C

Explanation

SSH (Secure Shell) is the preferred protocol for securely managing network devices as it provides encrypted communication. In contrast, a Bastion host is a security measure, Remote Desktop may not provide adequate security for device management, and a Split-tunnel VPN is primarily used for remote access rather than direct device management.
