A. Transitive trust
B. Federated ID
C. Non-transitive trust
D. Single sign-on
B. Federation is an arrangement that can be made among multiple enterprises (such as Facebook and Yahoo) that lets subscribers of one service use the same identification/authentication credentials to gain access to the second organizations resources. It differs from single sign-on (SSO) in that SSO is used within a single organization. Examples of SSO include Kerberos and Sesame. Answer A and C are incorrect as a transitive trust is a two-way relationship automatically created between parent and child domains. A non-transitive trust is a trust that will not extend past the domains it was created with. Both of these terms are directly associated with Microsoft operating systems.
