SSH is used to establish a secure connection between devices. Which option best reflects this?

• A. It establishes a secure connection between devices
• B. It transmits email securely
• C. It translates domain names
• D. It routes traffic between networks

Answer: (A)

SSH creates an encrypted, authenticated channel between two machines so you can log in remotely, run commands, or transfer files securely. This ensures confidentiality, integrity, and authentication of the session, which is exactly what “establishes a secure connection between devices” describes. It isn’t about securing email (that uses different mechanisms), translating domain names (DNS), or routing traffic between networks (routing is done by routers and different protocols). The core idea of SSH is providing a secure way to access and control another device over a network.
