• Question 14:

  Which of the following statements is true? SELECT ALL THAT APPLY

  A. The Service Composability principle is closely associated with the Service Reusability principle because service composition can be seen as a form of reuse.

  B. The Service Composability principle is highly revolutionary because the concept of aggregating software programs is new to distributed computing.

• Question 15:

  Which of the following is a common challenge imposed by the adoption of service-orientation? Select the correct answer.

  A. Service-orientation introduces the need for design standards, which need to be followed and enforced.

  B. Service-orientation requires that you commit to one vendor platform, which can limit your product options.
