Atask service

Bentity service

Cutility service

Ddata service

Answer : A

Question 3

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

AThe Service Composability principle is closely associated with the Service Reusability principle because service composition can be seen as a form of reuse.

BThe Service Composability principle is highly revolutionary because the concept of aggregating software programs is new to distributed computing.

CThe Service Composability principle emphasizes that services need to be designed to participate as effective members of multiple service compositions.

DThe Service Composability principle prepares services for immediate and eventual participation in compositions.

Answer : A, C, D

Question 4

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.

ATrue

BFalse

Answer : A

Question 5

Fundamental to service-orientation is the ability to continually recompose existing services into new compositions with minimal impact. This is why service-oriented technology architectures are required to be composition-centric. Select the correct answer.

ATrue

BFalse

Answer : A

Question 6

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

Aavailability (service downtime and periods of unavailability are minimized)

Bmaintainability (the service is easily evolved over time without disrupting existing relationships with service consumers)

Creliability (the service provides consistent results and performance)

DAll of the above.

Answer : D

Question 7

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

AThe 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.

BThe 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.

CThe 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.

DAll of the above.

Answer : D
