- BThe trust relationship uses XACML in the SAML header.
- CThe trust relationship uses SPML in the SOAP header.
- DThe trust relationship uses SPML in the SAML header.
Explanation
In web services provisioning, SPML (Service Provisioning Markup Language) uses SOAP as its transport protocol to carry provisioning messages between the Requesting Authority and the Provisioning Service Provider. To establish and convey trust (identity assertions and authentication tokens) between the two organizations, SAML (Security Assertion Markup Language) assertions are embedded in the SOAP header. This allows the PSP to verify the identity of the RA before processing provisioning requests. Answer A correctly describes SAML being used within the SOAP header as the trust mechanism in this federated relationship.
