Which of the following is not a meta abstraction type associated with the Service
Abstraction principle? Select the correct answer.

• A.state
• B.functional
• C.technology
• D.programmatic

I have a service that is required to access a shared database. When the load on the
database is heavy (for example when the billing department is running reports) my service
often times-out and returns a fault to the service consumer. Which service-orientation
principle should I apply to address this problem? Select the correct answer.

• A.Service Reusability
• B.Service Autonomy
• C.Service Discoverability
• D.Service Loose Coupling

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.

Which of the following statements correctly explains the difference between the Service
Reusability and Service Composability principles? Select the correct answer.

• A.Service Reusability is focused on creating non-agnostic service logic, whereas Service
  Composability is focused on creating agnostic service logic.
• B.There is no difference between these two principles. One principle name is used instead
  of the other depending on whether you are building a task or entity service.
• C.Service Reusability is focused on creating generic, reusable service logic, whereas
  Service Composability is focused on creating services that are effective participants of
  multiple service compositions.
• D.Service Reusability is focused on creating highly scalable services, whereas Service
  Composability is focused on creating highly isolated services.

Which of the following statements does not make sense? Select the correct answer.

• A.Since the design standards created in support of the Standardized Service Contract
  principle have been more widely enforced, I've noticed the same data models being shared
  by more services.
• B.All of these statements make sense.
• C.It is thanks to the Standardized Service Contract principle that we have been able to
  better isolate our services so as to reduce their dependency on shared databases.
• D.By applying the Standardized Service Contract principle, the amount of data model
  transformation logic required by my solution has been reduced.
