• Question 81:

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

  A. When using WS-AtomicTransaction, services participating in a transaction vote on the outcome so as to communicate whether the transaction should be rolled back or committed.

  B. When using WS-AtomicTransaction, services participating in a transaction use RPC protocols to communicate transaction results, so as to communicate whether the transaction should be rolled back

  or committed.

  C. When using WS-AtomicTransaction, services participating in a transaction rely on the use of WS-Policy definitions to confirm the transaction results.

  D. When using WS-AtomicTransaction, services do not actually participate in a transaction. This specification governs intra-service transactions (transactions that occur within a service boundary) only. WS-BusinessActivity provides cross-service transaction protocols.

  Correct Answer: A

  B. XML and XML Schema allow for the creation of data models that can be used by services, but can also establish a separate data architecture.

  C. XML and XML Schema are always used to define the structure of the underlying service logic as well as the component composition models the services may need to encapsulate.

  D. XML and XML Schema are important because when services are built as Web services, they must be used to define service scalability characteristics and thresholds, as established by the infrastructure.
