• Question 71:

  The Protocol Bridging pattern addresses problems that occur when services using different transport protocols or different versions of the same transport protocol try to communicate.

  A. True

  B. False

  Correct Answer: A

• Question 72:

  Which of the following statements is false?

  A. When applying the Data Format Transformation pattern, data format transformation logic can be the responsibility of a service fa?ade component that is tasked with converting between proprietary and standardized data formats.

  B. The Data Format Transformation pattern is applied in situations where there is a need to convert data between disparate XML schemas.

  C. Some transport protocols can be associated with specific data formats, in which case it makes sense to apply the Data Format Transformation pattern together with the Protocol Bridging pattern.

  D. The Data Format Transformation pattern is one of the patterns that comprise the Service Broker pattern.

  Correct Answer: B

• Question 73:

  Because the Service Broker pattern is part of the Enterprise Service Bus pattern, the Schema Centralization pattern is also considered part of the Enterprise Service Bus pattern.

  A. True

  B. False

  Correct Answer: B

• Question 74:

  The application of the Intermediate Routing pattern relies on the use of service agents. In order for the pattern to be applied properly, these service agents must be active in that they must change data within the message as part of their routing functionality.

  A. True

  B. False

  Correct Answer: B

• Question 75:

  A common XML-based technology used to apply the Data Model Transformation pattern is:

  A. XHTML

  B. WS-Policy

  C. WSDL

  D. None of the above.

  Correct Answer: D

• Question 76:

  Two services need to exchange a business document that exists as an XML document. Each service's contract uses a different XML schema to represent the business document structure. This results in two different XML representations for the same business data. Which of the following patterns can be used to enable the exchange of the business document between these two services?

  A. Data Format Transformation

  B. Protocol Bridging

  C. Atomic Service Transaction

  D. Data Model Transformation

  Correct Answer: D

• Question 77:

  Which of the following statements about the subscriber role established by the application of the Event-Driven Messaging pattern is true?

  A. a service can have multiple consumers as subscribers

  B. a consumer can only subscribe to one service

  C. a service can only have one consumer as a subscriber

  D. All of these statements are true.

  Correct Answer: A

• Question 78:

  If a service consumer program needs to get data from a service that is not available, it can poll the service by periodically issuing a request message. This type of interaction can be inefficient because it can lead to unnecessary message transmissions. Which of the following statements describes a solution to this problem?

  A. By applying the Messaging Metadata pattern, the service consumer can write a request identifier in the message header. Service agents then intercept the request messages and do not forward those that contain a previously detected identifier. This practice eliminates the delivery of the duplicate messages to the service.

  B. The Event-Driven Messaging pattern can be applied to establish a messaging framework in which service consumers are automatically notified of relevant runtime service events.

  C. By applying the Atomic Service Transaction pattern, a service can be designed to invoke an alternative exception handling process when it is unavailable to receive a given message.

  D. None ofthesestatements describe solutions that directly solve this problem.

  Correct Answer: B

• Question 79:

  The messaging framework established by the application of the Event-Driven Messaging pattern positions a(n) as being responsible for the broadcast of event notification messages.

  A. event management program

  B. synchronous queue

  C. event-driven Web service

  D. database

  Correct Answer: A

• Question 80:

  Based on the publisher and subscriber roles established by the application of the Event- Driven Messaging pattern, which of the following statements are true?

  A. a service, acting as a publisher, issues event notification messages to an event management program that is responsible for broadcasting the messages

  B. a service consumer, acting as a subscriber, can selectively subscribe to specific events

  C. an intermediate event management program enters the role of subscriber when accepting event subscriptions

  D. upon receiving a message associated with an event that a service consumer subscribed to, the service consumer enters the publisher role

  Correct Answer: AB
