CompTIA A+ Core 1 (220-1101) — Question 409

Which of the following protocols can be used to securely access a remote network to troubleshoot various devices?

Answer options

• A. FTP
• B. RDP
• C. SSH
• D. TFTP

Correct answer: C

Explanation

SSH (Secure Shell) is designed for secure communication and provides encrypted access to remote devices, making it suitable for troubleshooting. FTP (File Transfer Protocol) and TFTP (Trivial File Transfer Protocol) do not offer security features, and while RDP (Remote Desktop Protocol) provides remote access, it is not primarily focused on secure command-line troubleshooting.
