• Question 82:

  Which of the following statements are false?

  A. The Compensating Service Transaction pattern is often applied by calling one or more "undo" operations provided as service capabilities of the services participating in a composition.
  B. A compensating service transaction must be designed independently and without knowledge of the technical service contracts belonging to the composition members.
  C. Compensating logic is generally expressed in its own process definition and separated from the overall service composition logic.
  D. The Compensating Service Transaction pattern is one of the core patterns that comprise the Enterprise Service Bus compound pattern.
  B. A compensating service transaction must be designed independently and without knowledge of the technical service contracts belonging to the composition members.

• Question 83:

  When applying the Schema Centralization pattern, multiple services can form dependencies on the same centralized schema.

  A. True
  B. False
  A. True

• Question 84:

  A service agent has a technical contract that allows it to be explicitly invoked by service consumer programs.

  A. True
  B. False
  B. False

• Question 85:

  C. non-agnostic, agnostic, agnostic

• Question 86:

  Two services need to exchange a business document that exists as an XML document. Each service's contract uses a different XML schema to represent the business document structure. This results in two different XML representations for the same business data. Which of the following patterns can be used to enable the exchange of the business document between these two services?

  A. Data Format Transformation
  B. Protocol Bridging
  C. Atomic Service Transaction
  D. Data Model Transformation
  D. Data Model Transformation

• Question 87:

  Which of the following statements is true?

  A. A compensating service transaction always exists within the scope of an atomic service transaction.
  B. The application of the Compensating Service Transaction pattern relies heavily upon an underlying database that supports the rollback of changes.
  C. A compensating service transaction is only used in situations where the rollback of changes across services needs to be guaranteed.
  D. None of these statements are true.
  D. None of these statements are true.

• Question 88:

  Business process logic is abstracted and physically centralized as part of a platform that supports long-running service activities via the use of a database that can temporarily store state data during periods of inactivity. Which of the following compound patterns provides the range of features required to support these requirements?

  A. Enterprise Service Bus
  B. Service Broker
  C. Orchestration
  D. Official Endpoint
  C. Orchestration

• Question 89:

  Which of the following is a common problem associated with the application of the Policy Centralization pattern?

  A. Changes to a shared policy definition can affect all services that rely upon it, which in turn, can affect all service consumers that have formed dependencies on the corresponding service contracts.
  B. Changes to a shared data model can affect all services that rely upon it, which in turn, can affect all service consumers that have formed dependencies on the corresponding service contracts.
  C. Changes to a shared database can affect all services that rely upon it, which in turn, can affect all service consumers that have formed dependencies on the corresponding service contracts.
  D. None of the above.
  A. Changes to a shared policy definition can affect all services that rely upon it, which in turn, can affect all service consumers that have formed dependencies on the corresponding service contracts.

• Question 90:

  Which of the following statements accurately describes the difference between the Atomic Service Transaction pattern and the Compensating Service Transaction pattern?

  A. The Atomic Service Transaction pattern is more suitable in situations that require real-time activity processing, whereas the Compensating Service Transaction pattern is more suitable for long-running activity processing.
  B. The Atomic Service Transaction pattern provides support for the rollback of changes, whereas the Compensating Service Transaction pattern does not.
  C. The Atomic Service Transaction pattern does not rely on pre-defined alternative exception handling logic, whereas the Compensating Service Transaction pattern does.
  D. All of the above.
  D. All of the above.
