Which command is used to end a configuration session in Cisco IOS?

#end
#exit
#commit
#quit

The correct answer is: #end

The command used to end a configuration session in Cisco IOS is "end." When you type "end" in the command-line interface, it terminates the current configuration mode and returns you to the privileged EXEC mode. This command is essential for saving your place in the hierarchy of configuration modes and allows you to apply the changes made during the session. Other commands such as "exit" are used to leave a specific configuration sub-mode or to log out of the Cisco device entirely, depending on the context in which it is issued. "Commit" is a command found in other types of devices, like those running Junos OS, used to save changes, but it does not apply to Cisco IOS. Similarly, "quit" has similar behavior to "exit" but is less commonly used in Cisco IOS. Understanding these distinctions is crucial for correct device management and navigation within IOS.
