What command is used to enter privileged exec mode from user exec mode?

To enter privileged exec mode from user exec mode on a Cisco device, the command "enable" is utilized. When executing this command, the user is prompted to enter a password if one has been set for accessing privileged exec mode. Privileged exec mode allows users to execute advanced commands that can modify the configuration and access device management options, which are not available in the limited user exec mode.

The enable command effectively elevates the user's access level, providing the necessary privileges to perform critical tasks such as configuring interfaces, viewing system logs, and making changes to the running configuration of the device. This command is fundamental for network administrators who need to manage and troubleshoot Cisco devices.

In contrast, the "configure terminal" command is used to enter global configuration mode from privileged exec mode, not from user exec mode. The "exit" command is used to leave the current mode or log out of the device but does not change access levels. Similarly, "show running-config" is a command that displays the current configuration of the device but does not change the mode of access. Thus, "enable" is the command specifically designed for transitioning from user exec mode to privileged exec mode.
