• Question 43:

  Identify what is wrong with this statement: "SOAP-based Web services A and B are participating in a runtime transaction that is carried out as per the WS-AtomicTransaction standard. When a message sent by Service A is rejected by Service B due to a violation of a WS-Policy definition expressed as part of the Service B contract, Service A is forced to issue an Abort message, thereby requiring the transaction to be rolled back." Select the correct answer.

  A. WS-AtomicTransaction does not support the rollback of changes that occur during runtime transactions.
  B. WS-Policy definitions are not expressed as part of the service contract.
  C. SOAP-based Web services cannot have policies and cannot participate in runtime transactions because they are limited to the use of a uniform service contract.
  D. There is nothing wrong with this statement.
  A. WS-AtomicTransaction does not support the rollback of changes that occur during runtime transactions.

• Question 44:

• Question 45:

  Which of the following statements are true? SELECT ALL THAT APPLY

  A. XML and XML Schema can be used to help define the technical service contract of a SOAP-based Web service.
  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.
  A. XML and XML Schema can be used to help define the technical service contract of a SOAP-based Web service.
  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.

  Which of the following can be part of technical service contract? Select the correct answer.

  A. WSDL operation
  B. component method
  C. HTTP method
  D. Each of the above can be part of a technical service contract, depending on which technology platform is chosen to build the service.

  B. WS-Coordination establishes a base coordination framework for which XML Schema and WS- Addressing provide additional protocols and rules.
  C. WS-Coordination establishes a base coordination framework for which WS-AtomicTransaction and WS-BusinessActivity provide additional protocols and rules.
  D. WS-Coordination does not establish a base coordination framework. The name of the specification is deceiving as it actually defines a series of generic routing protocols.
  C. WS-Coordination establishes a base coordination framework for which WS-AtomicTransaction and WS-BusinessActivity provide additional protocols and rules.

• Question 50:
