Which of the following statements is 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 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.
• C. "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.
• 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.

When migrating to a service-oriented computing platform you are working toward achieving a specific target environment. Which of the following statements about this target environment are true? SELECT ALL THAT APPLY

• A. In this target environment, services are naturally interoperable and composable.
• B. This target environment helps the organization itself gain greater value from IT, because IT imposes less of a burden on the organization."
• C. In this target environment, services establish a federated endpoint layer.
• D. In this target environment, business logic is accurately expressed through services as a result of collaboration between business analysts and technology experts.

Service-oriented computing aims to reduce the burden of IT upon the organization as a whole by reducing waste, operational cost, and overhead associated with the governance and evolution of the IT enterprise. Select the correct answer

• A. False
• B. True

Which of the following statements is false?

• A. The design standardization of service contracts helps avoid the need for transformation technologies.
• B. Design standardization is not relevant to the design of service compositions. It is only relevant to the design of individual services.
• C. Design standardization can introduce organizational and cultural challenges because it requires that the design standards be regularly enforced.
• D. The design standardization of service contracts helps increase interoperability between services.

Which of the following statements does not make sense?

• A. Intrinsic interoperability is important because it enables services to exchange data without having to resort to transformation technologies.
• B. Intrinsic interoperability is important because it is fundamental to enabling services to be repeatedly composed.
• C. 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.
• D. Intrinsic interoperability is important because one of the goals of service-oriented computing is to increase intrinsic interoperability.
