If a user needs to be in privileged EXEC or enable mode, which part of AAA must succeed?
- authentication
- accounting
- administration
- authorization
Explanation: While authentication is the process of identifying a user, authorization is the component of the AAA framework that determines the level of access a user has and what they are permitted to do. Specifically, authorization allows an administrator to define which privileged EXEC commands are available to a user.
When a user attempts to access a specific service or enter a mode like privileged EXEC (enable) mode, the device queries the authorization server. The server can then return a specific privilege level (such as level 15) for the user, granting them the permission required to operate in that mode. It is important to note that while authorization requires a successful authentication to proceed, it is the authorization step that specifically validates the user's right to access privileged modes.
