A. functional

B. technology

C. programmatic

D. state

Which of the following statements reveal common misunderstandings about service-orientation and SOA? SELECT ALL THAT APPLY

A. In order for an enterprise to be successful with SOA, enterprise-wide standardization is required.

B. Service-orientation is a revolutionary paradigm that is incompatible with existing paradigms and practices.

C. Adoption of service-orientation will return an immediate ROI due to its focus on tactical (short- term) requirements fulfillment.

D. In order for an enterprise to be successful with SOA, an understanding of service- orientation is required.

Which of the following is a common reason as to why the Standardized Service Contract principle is not followed in some organizations? Select the correct answer.

A. Development tools are used to auto-generate the details of the technical service contract.

B. Developers ignore service contract design standards.

C. Developers are required to use pre-defined third-party service contracts obtained with the purchase of legacy system adapters.

D. All of the above.

The definition of the Service Composability design principle is as follows: "Services are effective composition participants, regardless of the size and complexity of the composition." What is meant by "regardless of the size and complexity of the composition"? Select the correct answer.

A. It means that services need to be designed so that they can participate in different types of compositions, regardless of what type of composition they are initially delivered for.

B. It means that services need to be designed for a specific composition with a specific size and level of complexity, regardless of what other compositions may need to use the service for in the future.

C. It means that the composition must be large and complex, regardless of the size and complexity of the service itself. These two design aspects need to be kept separate so that service and composition can evolve independently.

D. The definition for the Service Composability principle does not include the statement "regardless of the size and complexity of the composition".

A service's functional context determines its: Select the correct answer.

A. purpose and function

B. implementation environment and deployment location

C. scalability and usage thresholds

D. longevity and versioning parameters

Fill in the blank for the following definition of the Service Abstraction design principle:

" only contain essential information and information about services is limited to what is published in service contracts." Select the correct answer.

A. Service messages

B. Service contracts

C. Service types

D. Service activities

The Service Reusability principle can services demands on infrastructure because that are reused will typically have reliability security, performance, and requirements. Select the correct answer.

A. increase, reduced

B. decease, reduced

C. eliminate, no

D. None of the above.

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

A. The application of service-orientation leads to reduced awareness of underlying service implementation details because the Service Abstraction principle advocates limiting what is published about services.

B. The application of service-orientation leads to increased consistency in how functionality is expressed in the service contract because the Service Reusability principle advocates deferring service contract information at runtime.

C. The application of service-orientation leads to increased behavioral predictability and increased availability and scalability as a result of applying the Service Autonomy and Service Statelessness design principles.

D. The application of service-orientation leads to increased awareness of available services because the Service Discoverability design principle advocates improving the communications quality of published service information.
