What is the command to enter privileged EXEC mode from user EXEC mode?

To enter privileged EXEC mode from user EXEC mode, the command used is "enable." This command elevates the user’s access level, allowing them to execute commands that can configure or change router and switch settings. User EXEC mode offers limited access for basic monitoring and troubleshooting tasks, whereas privileged EXEC mode provides access to more sensitive commands and configurations, making the distinction between these modes crucial for maintaining network security and control.

The other choices do not serve the same purpose. For example, "configure terminal" is a command used to enter global configuration mode from privileged EXEC mode, while "logout" will terminate the current session. "exec privileged" is not a standard command used in Cisco IOS for this purpose, making it an incorrect choice for switching to privileged EXEC mode.
