Your customer has created a rule so that every time a user wants to go to Internet, that user must
be authenticated. The customer requires an authentication scheme that provides transparency for
the user and granular control for the administrator. User must also be able to log in from any
location. Based on this information, which authentication schemes meets the customer’s needs?

A.
Session

B.
User

C.
Client

D.
Dual

E.
Reverse

Explanation:
As it says in the question, the administrator wants granular control and that requires authentication
in a user basis, he also wants logging from any place, so the best option is to use “User
Authentication” because we can have a centralized user database that will provide successfully
provide the mobility requirements exposed in the question.
Incorrect Answers:
A: Session authentication does not provide the mobility requirements because the user will have to
install the session authentication agent on every PC and that’s not a transparent experience for
him.
C: Client authentication does not provide a transparent experience to the user because he / she
have to make a manual logon to the firewall with Telnet or HTTP.
D: This is not one of the 3 authentication methods supported by the NG suite.
E: This is not one of the 3 authentication methods supported by the NG suite.
