  Correct Answer: B

• Question 63:

  Often it is a requirement to wrap a legacy system with a service. This is typically accomplished by encapsulating calls to the legacy system's Application Programming Interface (API) within the core logic of the service.

• Question 68:

  The Service Discoverability principle is supported by the Standardized Service Contract principle in which of the following ways? Select the correct answer.

  A. The Standardized Service Contract principle advocates using naming conventions for ensuring that the functionality of services is consistently expressed. By making the service easier to understand, it becomes more discoverable.

  B. The Standardized Service Contract principle supports a design process whereby the service contract is customized and created prior to the service logic. This allows service designers to shape the service contract content in such a manner that it can be effectively discovered.

  C. The Standardized Service Contract principle requires the use of service contract design standards that can be created to establish conventions that are supportive of the Service Discoverability principle.

  D. All of the above.

  Correct Answer: D
