[2026] SOA Design & Architecture - S90.03 무료 시험 문제

문제1

Which service-orientation principle influences the content published about services and
further helps avoid the misinterpretation of service contracts? Select the correct answer.

A. Service Statelessness

B. Service Autonomy

C. Service Discoverability

D. None of the above.

정답: C

문제2

My service was consuming too much memory so I chose to persist data between
invocations to a database. After doing so, I found that the performance of my service
declined significantly due to the fact that my database is shared with other applications. As
a result, I further isolated the service by giving it its own dedicated database. Which
service-orientation principles were involved in this scenario? Select the correct answer.

A. Service Statelessness

B. Service Loose Coupling

C. Service Autonomy

D. Service Reusability

정답: A,C

문제3

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

A. The adoption of service-orientation can result in an emphasis on tactical (short-term)
rather than strategic (long-term) planning in order to justify a quick ROI.

B. The adoption of service-orientation can result in increased design complexity due to a
constant emphasis on reuse.

C. The adoption of service-orientation can result in an increased overall time and cost for
the initial delivery of service logic.

D. The adoption of service-orientation can result in a need to introduce a governance
structure that may introduce new organizational roles and processes.

정답: B,C,D

문제4

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

A. Increasing the quantity of data model transformation logic within a service composition
results in an increase in the development effort required to build the service composition
due to an increase in the necessary data model mapping logic.

B. Increasing the quantity of data model transformation logic within a service composition
results in a decrease in the performance of the service composition due to the need to
execute the data model mapping logic at runtime.

C. Increasing the quantity of data model transformation logic within a service composition
results in an increase in the architectural complexity of the service composition due to the
incorporation of the additional data model transformation layers.

D. Increasing the quantity of data model transformation logic within a service composition
results in a decrease in the development effort required to build the service composition
due to the fact that the intrinsic data model mapping logic residing within services can be
leveraged.

정답: D

문제5

Service compositions can only be assembled from services that belong to the same service
inventory. Select the correct answer.

A. True

B. False

정답: B

문제6

Which of the following is not a negative coupling type? Select the correct answer.

A. Contract-to-Technology

B. Consumer-to-Contract

C. Contract-to-Implementation

D. Contract-to-Logic

정답: B

문제7

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

B. 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.

C. 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.

D. All of the above.

정답: D

문제8

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

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

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

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

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

정답: A,C,D

문제9

Which of the following is not a design characteristic that is realized by the application of the
Service Reusability principle? Select the correct answer.

A. The service logic is generic.

B. The service is primarily associated with the task service model.

C. The service design approach is influenced by commercial product design practices.

D. The service is defined by an agnostic functional context.

정답: B

문제10

The "contract first" approach to building services helps realize contract-to-logic coupling.
Select the correct answer.

A. True

B. False

정답: B
