  A. Service messages
  B. Service contracts
  C. Service types
  D. Service activities
  B. Service contracts

• Question 23:

  C. decreased, Service Discoverability
  D. None of the above.
  D. None of the above.

• Question 24:

  A. stateful, passive
  B. stateless, passive
  C. stateful, active

• Question 26:

  The definition of the Service Composability design principle is as follows: "Services are effective composition participants, regardless of the size and complexity of the composition." What is meant by "regardless of the size and complexity of the composition"? Select the correct answer.

  A. It means that services need to be designed so that they can participate in different types of compositions, regardless of what type of composition they are initially delivered for.
  B. It means that services need to be designed for a specific composition with a specific size and level of complexity, regardless of what other compositions may need to use the service for in the future.
  C. It means that the composition must be large and complex, regardless of the size and complexity of the service itself. These two design aspects need to be kept separate so that service and composition can evolve independently.
  D. The definition for the Service Composability principle does not include the statement "regardless of the size and complexity of the composition".
  A. It means that services need to be designed so that they can participate in different types of compositions, regardless of what type of composition they are initially delivered for.
