Which of the following statements is false? Select the correct answer.

A. A sub-controller capability is responsible for composing nested composition logic.

B. A sub-controller capability is responsible for composing other service capabilities.

C. A sub-controller capability composes other service capabilities while it itself is also composed by other service capabilities.

D. A sub-controller can only compose other service capabilities but it cannot itself be composed.

Which of the following statements is true? Select the correct answer.

A. A composition initiator must exist as a service.

B. A composition initiator can be any type of program capable of invoking a service and therefore does not need to be service-oriented.

C. A composition initiator is often associated with the intermediary role.

D. None of the above statements are true.

Fill in the blank for the following definition for the Service Loose Coupling design principle:

"Service contracts impose low __________________ requirements and are themselves decoupled from

their surrounding environment." Select the correct answer.

A. consumer coupling

B. granularity

C. legacy encapsulation

D. state deferral

As the quantity of services in service inventories increase, the potential for service compositions to become larger and more complex increases also. Select the correct answer.

A. True

B. False

The Service Discoverability principle is supported by the Standardized Service Contract principle in which of the following ways? Select the correct answer.

A. The Standardized Service Contract principle advocates using naming conventions for ensuring that the functionality of services is consistently expressed. By making the service easier to understand, it becomes more discoverable.

B. The Standardized Service Contract principle supports a design process whereby the service contract is customized and created prior to the service logic. This allows service designers to shape the service contract content in such a manner that it can be effectively discovered.

C. The Standardized Service Contract principle requires the use of service contract design standards that can be created to establish conventions that are supportive of the Service Discoverability principle.

D. All of the above.

Which of the following characteristics directly supports or enables behavioral predictability within services? Select the correct answer.

A. availability (service downtime and periods of unavailability are minimized)

B. maintainability (the service is easily evolved over time without disrupting existing relationships with service consumers)

C. reliability (the service provides consistent results and performance)

D. All of the above.

Which of the following is not an influence of service-orientation? Select the correct answer.

A. Object-Oriented Analysis and Design (OOAD)

B. Business Process Management (BPM)

C. Enterprise Application Integration (EAI)

D. Fluid Dynamics (FD)

A service is sometimes referred to as an enterprise resource because: Select the correct answer.

A. It establishes itself as a resource that is of use to more than one part of the enterprise.

B. It can only be defined by enterprise architects.

C. It always depends on the availability of enterprise legacy systems.

D. None of the above.

Which of the following does not represent a typical form of service contract standardization addressed by the Standardized Service Contract principle? Select the correct answer.

A. the standardization of a service's functional expression

B. the standardization of industry technologies across different service inventories

C. the standardization of data models used by service contracts

D. All of the above represent typical forms of standardization addressed by the Standardized Service Contract principle.

The decoupling of a service contract from the service's underlying implementation results in a(n) __________________ in the service's level of abstraction because __________________ service implementation details helps prevent service consumers from being designed to indirectly couple to the underlying service implementation. Select the correct answer.

A. increase, hiding

B. increase, publishing

C. decrease, hiding

D. decrease, publishing
