Which command would you use to exit from console line configuration mode?

1. exit

2. quit

3. leave

4. return

The correct answer is: exit

To exit from console line configuration mode, the command "exit" is utilized. This command is a standard part of Cisco IOS command-line interface (CLI) operations, where "exit" is recognized as the command to terminate the current session in various modes, including line configuration mode. When in line configuration mode, executing this command effectively returns the user back to the previous mode, which is typically the privileged EXEC mode. This behavior is consistent across different configuration levels, making "exit" a fundamental command for navigating within the Cisco IOS interface. The other options do not serve this function within the Cisco IOS environment. "Quit," "leave," and "return" are not recognized commands for closing the configuration mode and would not be effective in this context. Thus, understanding the use of "exit" is critical for effective navigation and configuration management within Cisco devices.
