Which of the following commands is not available to a user with a privilege level of 0? (Select the best answer.)

  • disable
  • enable
  • exit
  • login
  • logout
Explanation:
The login command is not available to a user with a privilege level of 0. Privilege levels can be used to limit the IOS commands that a user can access. The disable, enable, exit, help, and logout commands are available to a user with a privilege level of 0. Because the default privilege level for a newly created local user account is 1, a newly created user will always have access to the basic commands necessary to escalate their privilege level or access the help system. You can assign a user one of 16 privilege levels, some of which are used by default by the IOS. For example, privilege levels 1 and 15 are default IOS privilege levels. Privilege level 1 allows a user to issue any command that is available at the user EXEC > prompt. Privilege level 15 allows a user to issue any command that is available at the privileged EXEC # prompt.
Each privilege level is associated with a list of commands that are available at that level. Users assigned to a privilege level have access to all of the commands at that privilege level and all lower privilege levels. Changing the commands that are available to a privilege level might provide access to a user who should not be allowed access to the command, or it might restrict access to another user who should be allowed access to the command. Peruser privilege levels can sometimes conflict with the privilege levels set for virtual terminal (VTY) interfaces. In the event of a conflict, peruser privileges override the privileges configured for the VTY line causing the conflict.
