최신 S90.01 무료덤프 - SOA Fundamental SOA & Service-Oriented Computing

A. agnostic and reusable

B. linear and logistically decomposable

C. returnable and non-standardized

D. unidirectional and semi-granular

A. True

B. False

A. "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."

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. "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."

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."

A. service contracts

B. all of the above

C. business services

D. service registries

A. It can't. The service must only provide one service capability in order for it to be accessible by service consumers.

B. Each service capability represents a function that the service has to offer. The service consumer can invoke and interact with one service capability at a time, thereby only using a subset of the service's overall functionality.

C. Service capabilities are designed to be composed together, which means that in order for a service consumer to interact with a service, it must be designed to invoke all of its service capabilities at the same time.

D. Services do not have service capabilities that are explicitly invoked. Services almost always exist as event-driven programs that transparently intercept service consumer messages at runtime.

A. "An application is considered service-oriented if it uses Web services."

B. "SOA projects always require enterprise-wide standardization and enterprise-wide global data models."

C. "The successful adoption of SOA will help an organization become more agile and responsive."

D. "It is required that you stick with a single SOA vendor platform in order to successfully achieve the strategic goals of service-oriented computing."

A. The design standardization of service contracts helps increase interoperability between services.

B. The design standardization of service contracts helps avoid the need for transformation technologies.

C. Design standardization can introduce organizational and cultural challenges because it requires that the design standards be regularly enforced.

D. Design standardization is not relevant to the design of service compositions. It is only relevant to the design of individual services.

A. 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.

B. 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.

C. 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.

D. 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.

A. through the creation of business services because this enables services to encapsulate and express business logic

B. through the creation of a vendor-specific architecture because this supports both the vendor-neutral and business-driven SOA characteristics

C. through the use of a business registry because this allows for the centralized registration of business analysts

D. through the use of a service registry because this allows business and technology- centric services to be located in the same place

A. 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.

B. 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.

C. 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.

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.
