SOA Technology Concepts: S90.02

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.

The amount of services participating in a service activity, the duration of the service activity, the amount of service activity instances that concurrently exist, and rules associated with the service activity are all examples of: Select the correct answer.

A. design-time data that is defined via the WSDL data definition language

B. runtime data that is expressed as part of a WSDL service operation definition

C. state or context data that can be managed using WS-Coordination

D. repository resource data that can be managed using WS-Policy via persistence in a database for longterm storage

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

A. Individual service contracts do not need to be published for SOAP-based Web services. Instead, they use a uniform contract.

B. Individual service contracts do not need to be published for REST services. Instead, they use a common uniform contract.

C. Components provide published contracts, but when building services as components, components must use a uniform contract instead.

D. None of these statements are true.
