Which of the following is not a benefit of the Diameter protocol?
A.
Allows for different services to be authenticated in one architecture instead of individual architectures
B.
Allows for the use of Mobile IP in an existing environment
C.
Relieves the restriction of only being able to authenticate users over PPP and SLIP connections
D.
Increases customer cost because of the different policy servers that must be maintained
Explanation:
Up until the conception of Diameter, IETF had individual working groups who definehow Voice over IP (VoIP), Fax over IP (FoIP), Mobile IP, and remote authenticationprotocols work. Defining and implementing them individually in any network caneasily end up in too much confusion and interoperability. It requires customers toroll out and configure several different policy servers and increases the cost witheach new added service. With Diameter all of these services can be authenticatedover the same authentication architecture.
