Which IOS mode is used to configure global device settings such as hostname?

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

Answer: (A)

Global configuration mode is where commands that apply to the whole device are entered. The hostname is a global property of the device, so it must be configured in this mode. You reach it by starting in user EXEC mode, entering privileged EXEC mode with enable, and then entering global configuration mode with configure terminal. In this mode you can set the hostname by typing hostname followed by the desired name. Other modes are for different purposes: user EXEC is just for basic access, privileged EXEC is for privileged commands but not for configuring the device's global settings, and line configuration mode is for configuring specific lines (like console or VTY) rather than the entire device. This is why the global configuration mode is the correct place to configure global settings like the hostname.
