Explanation
Identity Providers (IdPs) used in SAML-based SSO support authentication mechanisms that verify user identity. PKI/CAC (Public Key Infrastructure / Common Access Card) uses digital certificates for strong cryptographic authentication - commonly used in government and enterprise environments (Answer B). Kerberos is a widely used network authentication protocol that provides ticket-based SSO and is natively integrated with Active Directory and many IdPs (Answer E). UID is an identifier (not an authentication mechanism), ACS is a Cisco AAA server (not an IdP authentication method), and 'password only' is a credential type but not a named authentication mechanism in the context of IdP federation standards.
