  A. lesser, lesser

• Question 73:

  Which of the following are goals of the Service Reusability design principle? Select the correct answer.

  A. To support the creation of services based upon agnostic service logic.

  B. To allow for service logic to be repeatedly leveraged over time so as to achieve an increasingly high return on the initial investment of delivering the service.

  C. To increase organizational agility by enabling wide-scale service composition from service inventories that contains a high percentage of reusable services.

  D. All of the above.

  Correct Answer: D

• Question 74:

  Which of the following statements is true? Select the correct answer.

  A. The controller service in a service composition automatically loses autonomy because it is required to compose other services that lie outside of its controlled boundary.

  B. The controller service in a service composition automatically loses autonomy because it is designed as a task service to which service-orientation design principles are not applied.

  C. The controller service in a service composition loses autonomy only when state deferral logic is not built into the service composition design.

  D. None of these statements are true.

  Correct Answer: A

• Question 75:

  A. composition controller

  B. composition member

  C. composition sequencer

  D. composition sub-controller

• Question 76:

  Which of the following are considered characteristics associated with service-oriented technology architecture? Select the correct answer.

  A. vendor-neutral

  B. business-driven

  C. enterprise-centric

  D. All of the above

  Correct Answer: D

• Question 77:

  Which service-orientation principle would be used to justify a corporate policy that limits or restricts access to technical specifications that show design and technology details about the underlying implementation of a published service? Select the correct answer.

  A. Service Discoverability

  B. Service Statelessness

  C. Service Autonomy

  D. Service Abstraction

  Correct Answer: D

• Question 78:

  The service-oriented architectural model is business-driven so that it can stay in alignment with how the business may change over time. Select the correct answer.

  A. True

  B. False

  Correct Answer: A

• Question 79:

  I have a service composition with three services. Service A retrieves a list of country codes from a database and keeps this data in memory while interacting with Service B and Service C. However, because Service A is concurrently invoked many times, and because each instance of Service A loads its own copy of the country code data into memory, the demands on the overall infrastructure become too high and performance and reliability are negatively affected. Which service-orientation principle can be applied to help solve this problem? Select the correct answer.

  A. Service Reusability

  B. Service Autonomy

  C. Service Abstraction

  D. Service Statelessness

  Correct Answer: D

• Question 80:

  Which of the following is not a design characteristic that is realized by the application of the Service Reusability principle? Select the correct answer.

  A. The service is defined by an agnostic functional context.

  B. The service logic is generic.

  C. The service is primarily associated with the task service model.

  D. The service design approach is influenced by commercial product design practices.

  Correct Answer: C
