SOA Certified Professional Fundamental SOA & Service-Oriented Computing Sample Questions:
Question #1
Service-oriented computing advocates a concept based on the creation of a service layer with standardized and unified endpoints (service contracts) while allowing individual service implementations to remain disparate and independently governed. This concept is known as:
A. isolation
B. interoperability
C. transformation
D. federation
Question #2
A product or technology that is key to facilitating service discovery and service governance in general is a:
A. none of the above
B. business analysis tool
C. service registry
D. visual service development tool
Question #3
Which of the following is not the result of achieving the strategic goal of Reduced IT Burden?
A. a reduction in the quantity of services (compared to a traditional silo-based IT enterprise)
B. a reduction in waste and redundancy among automation solutions (compared to a traditional silo-based IT enterprise)
C. a reduction in size and operational cost of IT as a whole (compared to a traditional silo-based IT enterprise)
D. a reduction in the overhead associated with IT governance and evolution (compared to a traditional silo-based IT enterprise)
Question #4
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 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."
D. "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."
Question #5
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. False
B. True
Solutions:
| Question #1 Correct Answer: D | Question #2 Correct Answer: C | Question #3 Correct Answer: A | Question #4 Correct Answer: C | Question #5 Correct Answer: B |
