Selected Answer: B
REST – Assumes the application deals with communication failures via application retries  SOAP with WS-ReliableMessaging – Builds acknowledgement/retry logic into the communications stack – Can provide end-to-end reliability through one or more SOAP intermediaries

Selected Answer: B
Sounds like B is the most appropriate Because WS-ReliableMessaging includes acknowledgment and retry as part of the protocol A. SAML is “possible” with REST C. Specifications and formats can be provided in REST D. No restriction for XML/REST

A. SAML will force SOAP. SAML with REST specifications are still in approval process. SOAP WS Standards with SAML are quite well understood and used. Cannot be D because REST also has a schema that request response should adhere to. Just different format than XML Schemas. D would not mandate SOAP.
