Question 1

Common problems associated with silo-based application design include: SELECT ALL THAT APPLY

AIt can result in a significant amount of waste due to the fact that silo-based applications can have significant redundant functionality.

BIt can result in bloated, oversized technical environments.

CThe integration effort required to make disparate silo-based applications interoperate can be complex and expensive.

DIT operational costs can continue to escalate as more silo-based applications are added to an IT enterprise.

Answer : A, B, C, D

Question 2

By providing __________________ awareness of reusable services available for composition, the __________________ principle can greatly benefit the design of service-oriented solutions. Select the correct answer.

Aincreased, Service Statelessness

Bdecreased, Service Autonomy

Cdecreased, Service Discoverability

DNone of the above.

Answer : D

Question 3

Which of the following is a common challenge imposed by the adoption of service-orientation? Select the correct answer.

AService-orientation introduces the need for design standards, which need to be followed and enforced.

BService-orientation requires that you commit to one vendor platform, which can limit your product options.

CService-orientation requires that services be protected from repeated reuse, which can reduce potential ROI.

DService-orientation introduces the need to make all implementation details about each service publicly available, which can lead to the misuse of this information by some project teams.

Answer : A

Question 4

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 5

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.
