SOA S90-08A Online Questions & Answers

• Question 61:

  Each service composition within a service inventory shares the same service composition architecture.

  A. True
  B. False
  B. False

• Question 62:

  For a given service inventory architecture you would choose between an enterprise service bus product or an orchestration product, but you would not use both together.

  A. True
  B. False
  B. False

• Question 63:

  Which of the following statements are true?

  A. The application of the Rules Centralization pattern centralizes the governance of business rules so that they can be modified and evolved from a single location.
  B. The application of the Rules Centralization pattern reduces redundancy by centralizing common business rules-related logic that would normally be distributed across multiple services.
  C. The application of the Rules Centralization pattern results in centralized business rules that can be applied at runtime.
  D. The application of the Rules Centralization pattern can lead to a decrease in autonomy because it can introduce the need for an additional service to be part of service compositions.
  A. The application of the Rules Centralization pattern centralizes the governance of business rules so that they can be modified and evolved from a single location.

• Question 64:

  One SOA type can inherit the features and limitations of another SOA type with a broader scope. For example, the environment and conventions established by the service-oriented enterprise architecture can be carried over into individual service inventory architectures.

  A. True
  B. False
  A. True

• Question 65:

  A service inventory architecture is designed to accommodate the composition and recomposition of services.

  A. True
  B. False
  A. True

• Question 66:

  Assuming the Reliable Messaging pattern is successfully applied, which of the following statements is correct?

  A. A service agent intercepts and stores a message from the service consumer. The service agent then returns an acknowledgement back to the service consumer. Next, the service agent forwards the message to the service and when it receives an acknowledgement back from the service, it deletes the message.
  B. A service agent intercepts and stores a message from the service consumer. The service agent then forwards the message to the service. Next, the service agent receives an acknowledgement from the service, which it returns to the service consumer. Finally, the service agent deletes the message and related acknowledgements.
  C. The service consumer stores the message and forwards it to a service agent, which issues an acknowledgement back to the service consumer. The service agent then forwards the message to the service and when it receives an acknowledgement from the service, the service agent informs the service consumer so that it can delete the message and the acknowledgement.
  D. None of the above.
  A. A service agent intercepts and stores a message from the service consumer. The service agent then returns an acknowledgement back to the service consumer. Next, the service agent forwards the message to the service and when it receives an acknowledgement back from the service, it deletes the message.

• Question 67:

  Which of the following statements is true?

  A. The Legacy Wrapper pattern should not be applied in conjunction with the Process Centralization pattern because legacy systems do not possess enough autonomy to be effectively composed.
  B. The Messaging Metadata pattern can be applied to supplement messages with metadata that can be used for tracking purposes when also applying the Reliable Messaging pattern.
  C. The Protocol Bridging pattern is often used with the Legacy Wrapper pattern as a means of performing data model transformation between service inventory-wide data models created through the application of the Schema Centralization pattern and the underlying proprietary legacy format.
  D. All of these statements are true.
  B. The Messaging Metadata pattern can be applied to supplement messages with metadata that can be used for tracking purposes when also applying the Reliable Messaging pattern.

• Question 68:

  The application of the Redundant Implementation pattern can help increase service availability by establishing a duplicate deployment of a service in order to provide failover support.

  A. True
  B. False
  A. True

• Question 69:

  The Reliable Messaging pattern requires:

  A. the use of standardized service contracts in order to enable message atomic transaction details to be carried in the message header
  B. a framework for temporarily persisting messages and issuing acknowledgements
  C. the application of the Official Endpoint pattern in order to enable acknowledgement features
  D. a framework capable of bridging disparate messaging protocols in order to exchange schemas between compatible services
  B. a framework for temporarily persisting messages and issuing acknowledgements

• Question 70:

  A. XHTML
  B. WS-Policy
