What is the primary purpose of SSH?

• A. To log into another computer over a network
• B. To monitor network traffic in real time
• C. To broadcast messages to multiple machines
• D. To run on a local console only

Answer: (A)

SSH is used to securely log into a remote computer over a network, providing an encrypted channel to run commands, manage files, and perform administrative tasks on that system. It protects the session with encryption and authentication so data isn’t visible or tampered with as it travels over potentially insecure networks. This secure remote access is what makes SSH the preferred method for administering systems from afar, and it also enables secure file transfers and tunneling for other uses. The other options don’t fit because real-time network traffic monitoring is done with dedicated sniffing tools, not a remote login protocol; broadcasting messages to multiple machines requires a messaging or multicast system rather than a secure login channel; and SSH is specifically designed for remote access, not limited to a local console.
