A. Intrinsic interoperability is important because it helps increase the quantity of integration projects that may be required to accommodate new business requirements, thereby fostering agility.

B. Intrinsic interoperability is important because it enables services to exchange data without having to resort to transformation technologies.

C. Intrinsic interoperability is important because it is fundamental to enabling services to be repeatedly composed.

D. Intrinsic interoperability is important because one of the goals of service-oriented computing is to increase intrinsic interoperability.

A. To apply service-orientation requires the use of Web services.

B. Web services are required in order to build service-oriented solutions.

C. When discussing SOA and service-oriented computing, the term "Web service" must always be synonymous with (have the same meaning as) the term "service".

D. None of these statements are true.

A. "Contract first" design is important to SOA because it makes you think about service contract design options at the same time that you are building the underlying service logic.

B. "Contract first" design is important to SOA because it forces you to establish standardized service contracts prior to the development of the underlying service logic.

C. "Contract first" design is important to SOA because without a contract, services cannot be invoked. However, there is no preference as to when, during the service delivery lifecycle, the contract should be designed or established.

D. "Contract first" design is an unproven design technique that is not commonly employed when delivering service-oriented solutions and is therefore not considered important to SOA.
