Which of the following is not considered an AAA protocol?

A.
Diameter

B.
RADIUS

C.
TACACS+

D.
SESAME

Explanation:
Diameter, RADIUS, TACACS+ are referred to as AAA protocols, which stands for authentication, authorization, and auditing. (Some resources have the last A stand for accounting, but it is the same functionality – just a different name.) AAA protocols are developed to work in a client/server model, where the client can be a home user or a road warrior and the server is the central database that contains the
users credentials and authorization profiles. Diameter works in a peer-to-peer model, but is still considered an AAA protocol. SESAME is an authentication protocol similar to Kerberos.
