  B. False

  Correct Answer: A

• Question 42:

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

  A. A service inherits its functional context from its capabilities.

  B. A service capability inherits its functional context from other capabilities within the same service.

  C. A service inherits its functional context from other services, especially in complex compositions.

  D. A service capability inherits its functional context from its service.

  Correct Answer: D

• Question 43:

  A composition initiator is a variation of the composition controller role that represents nested composition logic. Select the correct answer.

  A. True

  B. False

  Correct Answer: B

• Question 44:

  Service compositions can only be assembled from services that belong to the same service inventory. Select the correct answer.

  A. True

  B. False

  Correct Answer: B

• Question 45:

  My service was consuming too much memory so I chose to persist data between invocations to a database. After doing so, I found that the performance of my service declined significantly due to the fact that my database is shared with other applications. As a result, I further isolated the service by giving it its own dedicated database. Which service-orientation principles were involved in this scenario? Select the correct answer.

  A. Service Loose Coupling

  B. Service Reusability

  C. Service Autonomy

  D. Service Statelessness

  Correct Answer: CD

• Question 46:

  The following statement describes the relationship between the Service Reusability principle and which other design principle? "Because of the potentially high performance and concurrent usage demands of reusable services, the extent of control they can exercise over their underlying environment is an important design consideration in guaranteeing an acceptable level of predictable runtime behavior." Select the correct answer.

  A. Standardized Service Contract

  B. Service Abstraction

  C. Service Autonomy

  D. Service Loose Coupling

  Correct Answer: C

• Question 47:

  Fundamental to service-orientation is the ability to continually recompose existing services into new compositions with minimal impact. This is why service-oriented technology architectures are required to be composition-centric. Select the correct answer.

  A. True

  B. False

  Correct Answer: A

• Question 48:

  Which of the following is not a negative coupling type? Select the correct answer.

  A. Contract-to-Technology

  B. Contract-to-Logic

  C. Contract-to-Implementation

  D. Consumer-to-Contract

  Correct Answer: D

• Question 49:

  The Service Loose Coupling principle is concerned with the relationship between the service contract and service consumers but also with the relationship between the service contract and whatever the service encapsulates. Select the correct answer.

  A. True

  B. False

  Correct Answer: A

• Question 50:

  Which of the following does not represent a typical form of service contract standardization addressed by the Standardized Service Contract principle? Select the correct answer.

  A. the standardization of a service's functional expression

  B. the standardization of industry technologies across different service inventories

  C. the standardization of data models used by service contracts

  D. All of the above represent typical forms of standardization addressed by the Standardized Service Contract principle.

  Correct Answer: B
