Which of the following characteristics directly supports or enables behavioral predictability
within services? Select the correct answer.

• A. maintainability (the service is easily evolved over time without disrupting existing
  relationships with service consumers)
• B. reliability (the service provides consistent results and performance)
• C. availability (service downtime and periods of unavailability are minimized)
• D. All of the above.

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

• A. Increasing the quantity of data model transformation logic within a service composition
  results in an increase in the development effort required to build the service composition
  due to an increase in the necessary data model mapping logic.
• B. Increasing the quantity of data model transformation logic within a service composition
  results in a decrease in the performance of the service composition due to the need to
  execute the data model mapping logic at runtime.
• C. Increasing the quantity of data model transformation logic within a service composition
  results in an increase in the architectural complexity of the service composition due to the
  incorporation of the additional data model transformation layers.
• D. Increasing the quantity of data model transformation logic within a service composition
  results in a decrease in the development effort required to build the service composition
  due to the fact that the intrinsic data model mapping logic residing within services can be
  leveraged.

Fill in the blanks for the following definition of the Service Discoverability design principle:
"Services are supplemented with communicative metadata by which they can be effectively
__________________ and __________________." Select the correct answer.

• A. discovered, refactored
• B. designed, discovered
• C. discovered, deployed
• D. discovered, interpreted

Which of the following statements correctly explains the difference between the Service
Abstraction and Service Loose Coupling principles? Select the correct answer.

• A. There is no difference between these two principles. One principle name is used instead
  of the other depending on whether you are building loose or tight service abstraction layers.
• B. Service Abstraction is focused on hiding information about service implementation
  details, whereas Service Loose Coupling is focused on the positioning of the service
  contract in relation to the service implementation and service consumers.
• C. Service Abstraction is focused on agnostic service logic only in order to establish an
  agnostic abstraction layer, whereas Service Loose Coupling is focused on the relationship
  between the service contract and service consumers.
• D. Service Abstraction is focused on dependencies that exist between the service contract
  and its underlying logic, whereas Service Loose Coupling is focused on fostering "loose
  state" in support of runtime state deferral
