SOA Multiple Choice Questions :-
1. Which of the following statements does not make sense?

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.
2. Which of the following statements is true?
A. To apply service-orientation requires the use of Web services.

3. 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 it forces you to establish standardized service contracts prior to the development of the underlying service logic.

11. What is wrong with this statement: “We delivered two services last year. Even though each service was delivered by a separate project team in a different location and at a different time, I am confident that the services will be reasonably interoperable because each project team was asked to use the same design standards.”
A. The statement is incorrect because services should never be delivered by different project teams.
B. The statement is incorrect because services rely on post-implementation integration effort in order to achieve interoperability, not design standards.
