Fundamental SOA & Service-Oriented Computing: S90.01

"A primary focus of service modeling is the encapsulation and abstraction of business logic in support of defining business service candidates." What is wrong with this statement?

A. Service modeling is a phase dedicated to defining non-business service logic only.

B. There is no such thing as a business service when creating service-oriented solutions.

C. The service modeling process results in the implementation of services, not the definition of service candidates.

D. There is nothing wrong with this statement.

Project Team Alpha delivers Service A for Solution 1. Project Team Beta delivers Service B for Solution 2. Some time later, Project Team Omega wants to reuse Service A and Service B for its new Solution 3. How would Services A and B need to have been designed in order for Project Team Omega to successfully reuse these services without having to resort to a major integration project?

A. Services always require the use of transformation technologies in order to communicate. Therefore, major integration effort is unavoidable in this scenario.

B. Services A and B need to reside on the same physical server or workstation, thereby allowing them to be reused without the need for major integration effort.

C. Services A and B need to be standardized and designed with an emphasis on intrinsic interoperability so that they are compatible regardless of when or by which project team they are delivered.

D. Service A needs to be designed using a different vendor platform than ServiceB. This enables vendor diversity, thereby guaranteeing interoperability.

Which of the following statements is true?

A. For a service consumer to interact with a service it must comply to the requirements of the service contract.

B. The service contract is used to express meta data about a service for human consumption only, and compliance to the service contract by service consumers is therefore not required.

C. Service contracts are only used to access a service when the service consumer itself is not a service.

D. All of these statements are true.
