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."

Which of the following statements are false? SELECT ALL THAT APPLY

• A. Services benefit from design standardization because this supports service-oriented computing goals, such as Increased Intrinsic Interoperability.
• B. Services benefit from being concurrently invoked by different service compositions because this decreases their performance requirements while increasing their availability.
• C. Services benefit from a "contract first" approach because this allows the contract to be the first part of the service that is installed and further enables the contract to be subsequently changed without impact to service consumers.
• D. Services benefit from up-front analysis because this allows them to be modeled before they are developed and deployed.

Which of the following statements is true?

• A. Integration is the effort required to enable interoperability. A goal of service-oriented computing is to increase intrinsic interoperability, thereby reducing the need for integration.
• B. Interoperability is the effort required to enable integration. A goal of service-oriented computing is to increase intrinsic interoperability, thereby reducing the need for integration.
• C. Interoperability is the effort required to enable integration. A goal of service-oriented computing is to increase intrinsic integration, thereby reducing the need for interoperability.
• D. Integration is the effort required to enable interoperability. A goal of service-oriented computing is to increase intrinsic integration, thereby reducing the need for interoperability.

When enterprise-wide standardization is unattainable, multiple domain service inventories may need to be created instead of:

• A. multiple enterprise service registries
• B. a single enterprise service inventory
• C. multiple enterprise service inventories
• D. a single enterprise service registry

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.
