"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.

Complete the following statement with the correct sentence : "The objective of organizational agility is to dramatically reduce the time and effort required to fulfill new or changed business requirements...

A. service contract

B. service inventory

C. service container

D. none of the above

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.

D. All of these statements are true.

Below are excerpts from four different SOA adoption strategy documents. Based on your understanding of SOA, service-orientation, and the goals of service-oriented computing, select the adoption strategy that is clearly the most likely to succeed:

A. "As part of our planned transition toward service-orientation, we will continue to extend the existing legacy applications with transformation-centric middleware that will enable seamless integration and runtime conversion between the different data models and data formats used by these applications."

B. "Each of our existing legacy applications already establishes a domain boundary that is defined by the purpose of the application. We are confident that by leveraging these pre-defined silo-based boundaries we can create a series of effective domain service inventories, each with a scope that corresponds to a legacy application boundary."

C. "Our strategy fully supports the tactical (short-term) nature of service-oriented computing by de-emphasizing standardization and allowing different project teams to deliver services optimized to their respective requirements. This not only speeds the initial delivery of services, it further supports interoperability by enabling services to leverage established integration technologies."

D. "Our strategy is to make the consistent application of service-orientation principles a priority in order to support the attainment of the goals of service-oriented computing. The primary justification for this approach is the fact that we have identified the goals of service-oriented computing to be in alignment with our own business goals."

Service-oriented architecture must be designed to be both integration-centric and silo- based.

A. True

B. False

Non-agnostic solution logic is logic that is considered single-purpose because it is unique to a specific task, and therefore not useful to other tasks. Select the correct answer.

A. True

B. False

The goals of service-oriented computing are focused on tactical (short-term) benefits, as opposed to strategic (long-term) benefits. Select the correct answer.

A. True

B. False
