What is the reason that Kerberos and SESAME, among other products, can beaccessible through GSSAPI?

A.
Interoperability

B.
Functionality

C.
Redundancy

D.
Fault tolerance

Explanation:
Kerberos and SESAME can be accessed through a Generic Security Services ApplicationProgramming erface (GSSAPI), which is a generic API for client to server authentication. Using standard APIs allows for vendors to be able to communicate with and use each other functionality and security. By using a standard API products can intercommunicate, which is interoperability, because they know how to "talk to"each other products.
