Question 3

Which of the following statements are true? SELECT ALL THAT APPLY

  • A. The application of service-orientation leads to reduced awareness of underlying service implementation details because the Service Abstraction principle advocates limiting what is published about services.
  • B. The application of service-orientation leads to increased consistency in how functionality is expressed in the service contract because the Service Reusability principle advocates deferring service contract information at runtime.
  • C. The application of service-orientation leads to increased behavioral predictability and increased availability and scalability as a result of applying the Service Autonomy and Service Statelessness design principles.
  • D. The application of service-orientation leads to increased awareness of available services because the Service Discoverability design principle advocates improving the communications quality of published service information.

Question 6

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 generic, reusable service logic, whereas Service Composability is focused on creating services that are effective participants of multiple service compositions.
  • B. Service Reusability is focused on creating non-agnostic service logic, whereas Service Composability is focused on creating agnostic service logic.
  • C. Service Reusability is focused on creating highly scalable services, whereas Service Composability is focused on creating highly isolated services.
  • D. 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.

A
