What is the purpose of using SSH to connect to a router?

• A. It allows a secure remote connection to the router command line interface.
• B. It bypasses authentication.
• C. It transfers files only.
• D. It disables remote access.

Answer: (A)

SSH is used to manage routers securely over a distance. The essential idea is that it creates an encrypted, authenticated channel between your device and the router, so any login credentials and the commands you type are protected from eavesdropping or tampering as they travel across the network. This lets you access the router’s command-line interface to configure, monitor, and troubleshoot it remotely with confidence that unauthorized users can’t read or spoof the session. While SSH can also support secure file transfers (like SCP or SFTP), its primary purpose in this context is to provide a safe remote way to run management commands on the router. The other options don’t fit because SSH does not bypass authentication, is not limited to file transfers, and does not disable remote access—in fact, it enables secure remote access.
