Which IOS mode is used to configure an individual interface?

• A. Line configuration mode
• B. Global configuration mode
• C. Privileged EXEC mode
• D. User EXEC mode

Answer: (A)

Configuring a specific network interface happens in Interface Configuration Mode. You first move from the basic access mode to Privileged EXEC, then into Global Configuration Mode (config terminal). From there, you enter the interface you want to configure, for example interface FastEthernet0/1, which places you in Interface Configuration Mode. In this mode you set the interface’s IP address, description, speed, duplex, and other per-interface parameters. Line Configuration Mode is for configuring lines that provide access to the device, such as the console or VTY lines, not individual network interfaces. User EXEC mode is the limited, non-privileged mode you start in, while Privileged EXEC gives you access to configuration commands. So the correct place to configure an individual interface is Interface Configuration Mode.
