SOA S90-03A Online Questions & Answers

• Question 81:

  When applying the Service Loose Coupling design principle, we want to the coupling between the service contract and service consumers and the coupling of the service contract to its underlying logic. Select the correct answer.

  A. reduce, reduce
  B. reduce, increase
  C. increase, reduce
  D. increase, increase
  A. reduce, reduce

• Question 82:

  Which of the following are not service-orientation design principles? Select the correct answer.

  A. Service Abstraction
  B. Service Reliability
  C. Service Autonomy
  D. All of the above are service-orientation design principles.
  B. Service Reliability

• Question 83:

  Which are the three design principles that often act as regulators to ensure that the remaining five principles are properly applied: SELECT ALL THAT APPLY A. Service Loose Coupling

  B. Service Abstraction
  C. Service Composability
  D. Service Reusability
  B. Service Abstraction
  C. Service Composability

• Question 84:

  Each time our corporate development team makes a change to the service logic it is required to publish a new version of the service contract. Our customers are complaining because their service consumer programs become incompatible with new service contract versions and therefore no longer work. Which of the following service-orientation principles is most likely to help us solve this on-going problem? Select the correct answer.

  A. Service Reusability
  B. Service Statelessness
  C. Service Loose Coupling
  D. Service Autonomy
  C. Service Loose Coupling

• Question 85:

  Which of the following is not a state deferral option that is commonly used in support of applying the Service Statelessness principle? Select the correct answer.

  A. database
  B. utility service
  C. messages
  D. service registry
  D. service registry

• Question 86:

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

  A. Service compositions can challenge the traditional notion of interoperability because they rely heavily on integration and therefore make integration an intrinsic process of service delivery.
  B. Service compositions can challenge the traditional notion of integration because services are ideally designed to be intrinsically interoperable and therefore require less integration effort when assembled into service compositions.
  C. Service compositions can challenge the traditional notion of interoperability because they consist of distributed programs (services) and integration is rarely carried out across applications that are remotely distributed.
  D. None of the above statements are true.
  B. Service compositions can challenge the traditional notion of integration because services are ideally designed to be intrinsically interoperable and therefore require less integration effort when assembled into service compositions.

• Question 87:

  The decoupling of a service contract from the service's underlying implementation results in a(n) from being designed to indirectly couple to the underlying service implementation. Select the correct answer.

  in the service's level of abstraction because

  service implementation details helps prevent service consumers

  A. increase, hiding
  B. increase, publishing
  C. decrease, hiding
  D. decrease, publishing
  A. increase, hiding

• Question 88:

  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 emphasizes that services need to be designed to participate as effective members of multiple service compositions.
  D. The Service Composability principle prepares services for immediate and eventual participation in compositions.
  A. The Service Composability principle is closely associated with the Service Reusability principle because service composition can be seen as a form of reuse.
  C. The Service Composability principle emphasizes that services need to be designed to participate as effective members of multiple service compositions.
  D. The Service Composability principle prepares services for immediate and eventual participation in compositions.

• Question 89:

  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.
  D. All of the above.

• Question 90:

  When measuring coupling that exists between a service and a service consumer, you can determine the extent of dependency that exists between the service and service consumer. Select the correct answer.

  A. True
  B. False
  A. True
