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. "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."
• C. "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."
• 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."

I anticipate building larger service compositions comprised of more services. How will this likely affect performance and infrastructure?

• A. It will likely reduce performance demands and require an increase in infrastructure investment.
• B. It will likely increase performance demands and require an increase in infrastructure investment.
• C. It will not affect performance or infrastructure.
• D. It will likely increase performance demands and require a reduction in infrastructure investment.

Service metadata can be centrally registered within a __________ for discoverability purposes.

• A. service inventory
• B. service registry
• C. service model
• D. service composition

Solution logic is classified as "service-oriented" after:

• A. it has been built using Web services
• B. service-orientation has been applied to a meaningful extent
• C. it has been performance tested to a meaningful extent
• D. it has been built using RPC technologies

Service Composition A is comprised of 4 services. Service Composition B is comprised of 6 services. Because both service compositions are comprised of services from the same service inventory, the service inventory will have a total of how many services?

• A. Based on the information provided, it's impossible to know how many services reside in the service inventory because the quantity of services within a service inventory is not determined by the quantity of services in service compositions.
• B. 24
• C. 10
• D. Based on the information provided, it's impossible to know how many services reside in the service inventory because we don't know how many other service compositions exist.
