質問 1：
The application of the Intermediate Routing pattern can address which of the following needs?
A. The need to provide pre-defined compensating logic for when an atomic service transaction fails.
B. The need to increase the autonomy of a service due to its reliance on a shared data source.
C. The need for load-balanced access to a redundantly deployed service.
D. The need to perform content-based routing based upon metadata found in the message header.
正解：C,D

質問 2：

B. True
正解：B

質問 3：
The use of the Intermediate Routing pattern typically results in:

D. common routing logic being physically centralized into a single service
正解：A

質問 4：
Which of the following statements are true?
A. The Redundant Implementation pattern can be supplemented with the Intermediate Routing pattern, which can be applied to load balance access to a redundantly deployed service.
B. The Redundant Implementation pattern is concerned with eliminating single point of failure problems associated with services that are actively reused.
C. The Redundant Implementation pattern is most useful for services that possess non-agnostic service logic.
D. The Redundant Implementation pattern addresses issues of scalability, not issues of availability.
正解：A,B

質問 5：
Which of the following statements are false?
A. Compensating logic is generally expressed in its own process definition and separated from the overall service composition logic.
B. A compensating service transaction must be designed independently and without knowledge of the technical service contracts belonging to the composition members.
C. The Compensating Service Transaction pattern is one of the core patterns that comprise the Enterprise Service Bus compound pattern.
D. The Compensating Service Transaction pattern is often applied by calling one or more "undo" operations provided as service capabilities of the services participating in a composition.
正解：B,C

質問 6：
Which of the following statements is false?
A. 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.
B. The Messaging Metadata pattern can support the application of patterns such as Intermediate Routing by supplementing messages with activity-specific metadata.
C. 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.
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.
正解：D
