How should an administrator describe the difference between authentication and authorization?

選択肢

1. Authentication and authorization are two names for the same control, because both of them are evaluated at sign-in and can therefore be used interchangeably.
2. Authentication establishes who the requester is; authorization determines what that requester is allowed to do.
3. Authentication applies to administrators only; authorization applies to standard users only.
4. Authentication determines what a requester may do; authorization confirms the requester's identity.
