Which command allows a user to return to the previous level in the command hierarchy?

• A. exit
• B. end
• C. Ctrl-Z
• D. Ctrl-C

Answer: (A)

Returning to the previous level in the command hierarchy is done with the exit command. In the Cisco CLI, each mode represents a level (for example, interface configuration is a deeper level than global configuration, which is deeper than privileged EXEC). When you’re in a submode like interface configuration, typing exit moves you up one level—from interface configuration back to global configuration. You can keep using exit to step back through the levels until you reach the top-level privileged EXEC mode.

Other shortcuts behave differently: end and Ctrl-Z take you straight back to privileged EXEC, skipping intermediate levels, while Ctrl-C cancels the current command line but doesn’t reliably move you up a level. So exit is the precise way to move back one level at a time.
