A. Atomic Service Transaction

B. Asynchronous Queuing

C. Stateful Services

D. Service Data Replication

A. The application of the Legacy Wrapper pattern supports the Contract Centralization pattern by helping to establish a standardized contract through which to access legacy resources.

B. The application of the Legacy Wrapper pattern results in the coupling of the service contract to the legacy resources encapsulated by the service.

C. The application of the Legacy Wrapper pattern results in the coupling of the service consumer to the legacy resources encapsulated by the service.

D. None of these statements are true.

A. common routing logic being physically centralized into a single service composition

B. common routing logic being removed from service agents and placed into a database

C. common routing logic being physically centralized into a single service

D. common routing logic being removed from service logic and placed into service agents

A. service agents can process negative acknowledgements

B. service agents can load balance messages

C. service agents can route messages based on their content

D. service agents can process positive acknowledgements

A. False

B. True

A. Messaging frameworks and technologies need to provide support for the reading and writing of message headers or properties in order to fully support the application of the Messaging Metadata pattern.

B. The Messaging Metadata pattern can support the application of patterns such as Intermediate Routing by supplementing messages with activity-specific metadata.

C. Widespread use of the Messaging Metadata pattern can be seen in the emergence of many WS-* extensions that define industry standard SOAP header blocks that carry metadata.

D. The Messaging Metadata pattern is not applicable to situations where the message sender and receiver need to participate in stateful or conversational message exchanges.

A. The Legacy Wrapper pattern can be used to expose a legacy system as a SOAP-based Web service with a standardized technical service contract.

B. The application of the Policy Centralization pattern eliminates redundancy and inconsistency by creating a single, master policy bound to the WSDL definition of every service in a service inventory.

C. The Schema Centralization pattern supports the creation of independent data models that define data transmitted in SOAP messages.

D. The Decoupled Contract pattern results in the separation of the service contract from the service implementation, allowing the service contract to be independently designed and governed.

A. Transformation logic that performs runtime data model or data format conversion.

B. Protocol bridging logic that dynamically converts from one transport protocol to another at runtime.

C. Relaying logic that simply relays input and output messages to and from the core service logic.

D. Behavior correction logic used to compensate for changes in the behavior of the core service logic.
