D. SAML (Security Assertion Markup Language) E. X.509 (a standard for public key infrastructure) Prominent recommended standards to enable federation of identity in cloud environments include SAML (Security Assertion Markup Language) and X.509. These standards play essential roles in enabling secure authentication and authorization across different systems and services in cloud environments. SAML facilitates single sign-on (SSO) and identity federation, while X.509 defines the format for public key certificates used in various security applications, including authentication and digital signatures. FIDO (Fast Identity Online), Kerberos, and SSO (Single Sign-On) are also relevant to identity and authentication but are not specifically highlighted as recommended standards for enabling federation of identity in cloud environments in the context of the given options.
