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.

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.
