• Question 57:

  A service composition architecture with the following requirements needs to be created:

  1.

  Services will have different periods of availability.

  2.

  Sometimes the destination of a message cannot be determined until runtime.

  3.

  All the services do not support the same messaging protocol. Of the following choices, which patterns should be used to address these requirements?

  A. Event-Driven Messaging, Intermediate Routing, Atomic Service Transaction

  B. Protocol Bridging, Compensating Service Transaction, Asynchronous Queuing

  Correct Answer: D

• Question 58:

  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.

  Correct Answer: D

  Correct Answer: A

• Question 60:

  The Invoice service in an accounting firm is heavily reused by different service compositions. The owners of the service decide to protect its integrity by disallowing access to any part of its underlying implementation and further want to avoid the risk of having this service create a single point of failure.

  A. Contract Centralization, Decoupled Contract

  B. Domain Inventory, Redundant Implementation

  C. Data Model Transformation, Service Data Replication

  D. Contract Centralization, Redundant Implementation

  Correct Answer: D
