Question 3

The Reliable Messaging pattern requires:

A. a framework for temporarily persisting messages and issuing acknowledgements B. a framework capable of bridging disparate messaging protocols in order to exchange schemas between compatible services C. the use of standardized service contracts in order to enable message atomic transaction details to be carried in the message header D. the application of the Official Endpoint pattern in order to enable acknowledgement features

Correct Answer: A

Question 4

Correct Answer: A,B,C,D

Question 5

The Invoice service in an accounting firm is heavily reused by different service compositions.

B. The Atomic Service Transaction pattern does not rely on pre-defined alternative exception handling logic, whereas the Compensating Service Transaction pattern does. C. The Atomic Service Transaction pattern provides support for the rollback of changes, whereas the Compensating Service Transaction pattern does not. D. All of the above.

Correct Answer: D
