Question 1

Legacy systems often rely upon a combination of proprietary data models, proprietary data
formats, and proprietary transport protocols. For this reason the Legacy Wrapper pattern is
often used together with which of the following patterns?

A. Messaging Metadata B. Atomic Service Transaction C. Service Broker D. Service Messaging

Correct Answer: C

Question 2

Which of the following statements is true?

A. The Contract Centralization pattern specifies how to access a service through its
published contract, but it does not indicate which services should be accessed for specific
purposes. B. Although the Logic Centralization pattern addresses the question of how to avoid
redundant service logic, it does not address how the logic should be accessed. C. When the Logic Centralization and Contract Centralization patterns are applied together,
they realize the Official Endpoint pattern because they effectively establish an official
endpoint for a service. D. All of these statements are true.

Correct Answer: D

Correct Answer: B

Question 6

The application of the Legacy Wrapper pattern typically results in:

service D.
no coupling of the service logic to the service contract C. no coupling of the wrapper service logic to the service contract

Correct Answer: B

Question 7

Governance can become an issue with service agents because:
