Which concept is known as Federation, enabling identity information to be developed and shared among several entities across trusted domains?

• A. Identity Store
• B. Authentication
• C. Federation
• D. Credential

Answer: (C)

Federation is the practice of linking identities across trusted domains so that an identity asserted by one domain can be recognized and trusted by others. It relies on standards like SAML, OAuth, and OpenID Connect to exchange authentication tokens or assertions between an identity provider and relying parties, enabling cross-domain single sign-on and attribute sharing. This makes it possible for users to be authenticated by their home domain while accessing services in partner domains without re-entering credentials, while maintaining trust relationships among the domains involved. Identity Store is simply where identities are kept, usually within a single organization, and Authentication is the act of proving who you are. A Credential is the proof used in authentication (like a password or token). Federation specifically addresses trust and sharing of identity information across domain boundaries, which is why it is the correct choice.
