7 thoughts on “Which of the following privilege level is the most secured?

    1. By default, the Cisco IOS CLI has two privilege levels enabled, level 1 and level 15.
      + User EXEC mode (privilege level 1): provides the lowest EXEC mode user privileges and allows only user-level commands available at the Router> prompt.
      + Privileged EXEC mode (privilege level 15): includes all enable-level commands at the Router# prompt. Level 15 users can execute all commands and this is the most secured and powerful privilege level.

      However, there are actually 16 privilege levels available on the CLI, from 0 to 15 and you can assign users to any of those levels. Zero-level access allows only five commands -logout, enable, disable, help, and exit. User level (level 1) provides very limited read-only access to the router, and privileged level (level 15) provides complete control over the router.
