Which set of devices are commonly used to interact with a host server for making software and system configurations?

• A. Monitor, Keyboard, and Mouse
• B. Printer and Scanner
• C. USB Drive and Ethernet Cable
• D. Speaker and Microphone

Answer: (A)

To configure software and system settings on a host server, you need a display and input methods that let you see and interact with the interface. A monitor provides the visual interface, while a keyboard and mouse let you enter commands, navigate menus, and use configuration tools. This combination is what you use for direct, hands-on management of the server’s operating system and applications, especially during installation, changes, and setup wizards.

The other devices don’t support interactive configuration in the same way. A printer and scanner are for producing or scanning documents, not for configuring software. A USB drive and Ethernet cable can help with transferring files or establishing network connectivity, but they don’t give you an interactive interface for making settings. A speaker and microphone handle audio input and output and aren’t used for configuring the system.

In practice, servers can also be managed remotely via network access, but that still relies on an interface that is presented to the administrator—often through a remote console—while the local monitor, keyboard, and mouse are the traditional, direct interaction tools.
