Question #6 (Topic: )
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:
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."
Answer: D
Question #7 (Topic: )
An IT enterprise proceeds with an SOA initiative that is based on the creation of a
single enterprise service inventory. However, conflicts arise when different IT
departments disagree on who will own the services and how they will be governed.
Which of the following alternative approaches could be chosen to address these
conflicts?
single enterprise service inventory. However, conflicts arise when different IT
departments disagree on who will own the services and how they will be governed.
Which of the following alternative approaches could be chosen to address these
conflicts?
A. The top-down approach is chosen. This allows services to be modeled subsequent to their design, thereby enabling each service to be governed by multiple owners.
B. It is decided to proceed with the creation of multiple domain service inventories. This allows collections of services to be independently governed by different owners, while still enabling the IT enterprise as a whole to transition toward SOA.
C. The established "contract last" approach is chosen, allowing different IT managers to focus on contract-related governance issues after the services are deployed and in use.
D. Because SOA projects absolutely require enterprise-wide standardization and further demand the creation of an enterprise service inventory, the IT managers have no choice than to cancel the project.
Answer: B
Question #8 (Topic: )
Service-oriented computing advocates establishing a technology architecture with
increased vendor technology diversity, which means that service-oriented solutions
need to be consistently built using different vendor technologies and products. This
way, the failure of any one vendor technology or product will not bring down all
services within a service inventory. Select the correct answer.

A. True
B. False
Answer: B
Question #9 (Topic: )
A service can be a service consumer. Select the correct answer.
A. True
B. False
Answer: A
Question #10 (Topic: )
Which of the following statements makes sense?
A. I am going to register my new service in the service registry so that other project teams can discover it in order to determine whether they should reuse it as part of service- oriented solutions they are planning to build.
B. I am going to register my new service inventory in the service registry in order to improve the performance of my service-oriented solution, because other services in my service composition will be able to dynamically discover and retrieve the new service much faster than if it was not registered in the service registry.
C. I am going to register my new service in the service registry because Service Registration is one of the eight principles of service-orientation.
D. None of these statements make sense.
Answer: A
