What command do you use to terminate a configuration session in Cisco IOS?

1. #copy run start

2. #exit

3. #end

4. #terminate

The correct answer is: #end

To terminate a configuration session in Cisco IOS, the command "end" is employed to exit the current configuration mode and return to the privileged EXEC mode. This command is useful when you have finished making changes to the configuration and want to exit back to the higher-level mode where you can execute other commands or save your configuration. Using "end" is preferred because it clearly signifies that you are concluding the configuration session. In contrast, the other commands serve different purposes: "copy run start" is used for saving the current running configuration to the startup configuration, "exit" is used to exit from sub-modes (like sub-interface mode) but may not always mean leaving the entire configuration mode, and "terminate" is not a valid command in this context within Cisco IOS. Hence, "end" is the accurate choice for exiting the overall configuration session.
