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

Often it is a requirement to wrap a legacy system with a service. This is typically
accomplished by encapsulating calls to the legacy system's Application Programming
Interface (API) within the core logic of the service. Care must be taken to not expose
details of the underlying API through the service contract as it may unintentionally couple
the service consumer to the legacy system. Which pair of service-orientation principles
directly addresses this concern? Select the correct answer.

• A.Service Autonomy, Standardized Service Contract
• B.Service Statelessness, Service Autonomy
• C.Service Loose Coupling, Service Statelessness
• D.Service Loose Coupling, Service Abstraction

Fill in the blank for the following definition for the Standardized Service Contract design
principle: "Services within the same __________________ are in compliance with the
same contract design standards." Select the correct answer.

• A.state
• B.service activity
• C.message path
• D.service inventory

A service-oriented solution can be comprised of which of the following core architectural
elements? Select the correct answer.

• A.services
• B.messages
• C.All of the above.
• D.contracts

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

• A.The controller service in a service composition loses autonomy only when state deferral
  logic is not built into the service composition design.
• B.The controller service in a service composition automatically loses autonomy because it
  is required to compose other services that lie outside of its controlled boundary.
• C.None of these statements are true.
• D.The controller service in a service composition automatically loses autonomy because it
  is designed as a task service to which service-orientation design principles are not applied.
