Question 1

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. False B. True

Correct Answer: A

Question 2

The Process Centralization pattern is a part of which compound pattern?

A. Orchestration B. Enterprise Service Bus C. Official Endpoint layer D. Federated Endpoint layer

Correct Answer: A

Question 3

Business process logic is abstracted and physically centralized as part of a platform that
supports long-running service activities via the use of a database that can temporarily store
state data during periods of inactivity. Which of the following compound patterns provides
the range of features required to support these requirements?

A. Orchestration B. Enterprise Service Bus C. Service Broker D. Official Endpoint

Correct Answer: A

Question 4

Assuming you have technical service contracts for SOAP-based Web services, you can
apply the ___________ pattern through the use of ___________.

A. Message Metadata, SOAP message headers B. Policy Centralization, WS-Policy definitions C. Decoupled Contract, WSDL definitions D. Schema Centralization, XML schemas

Correct Answer: A,B,C,D

Question 5

Which of the following is a common problem associated with the application of the Policy
Centralization pattern?

A. Changes to a shared data model can affect all services that rely upon it, which in turn,
can affect all service consumers that have formed dependencies on the corresponding
service contracts. B. None of the above. C. Changes to a shared policy definition can affect all services that rely upon it, which in
turn, can affect all service consumers that have formed dependencies on the
corresponding service contracts. D. Changes to a shared database can affect all services that rely upon it, which in turn, can
affect all service consumers that have formed dependencies on the corresponding service
contracts.

Correct Answer: C

Question 6

Which of the following statements are false?

A. The Compensating Service Transaction pattern is one of the core patterns that comprise
the Enterprise Service Bus compound pattern. B. 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. C. Compensating logic is generally expressed in its own process definition and separated
from the overall service composition logic. D. A compensating service transaction must be designed independently and without
knowledge of the technical service contracts belonging to the composition members.

Correct Answer: A,D

Question 7

Assuming the Reliable Messaging pattern is successfully applied, which of the following
statements is correct?

A. None of the above. B. The service consumer stores the message and forwards it to a service agent, which
issues an acknowledgement back to the service consumer. The service agent then
forwards the message to the service and when it receives an acknowledgement from the
service, the service agent informs the service consumer so that it can delete the message
and the acknowledgement. C. A service agent intercepts and stores a message from the service consumer. The
service agent then returns an acknowledgement back to the service consumer. Next, the
service agent forwards the message to the service and when it receives an
acknowledgement back from the service, it deletes the message. D. A service agent intercepts and stores a message from the service consumer. The
service agent then forwards the message to the service. Next, the service agent receives
an acknowledgement from the service, which it returns to the service consumer. Finally, the
service agent deletes the message and related acknowledgements.

Correct Answer: C

Question 8

A service fa?ade component can be used to abstract the part of a service architecture that
has negative coupling potential.

A. False B. True

Correct Answer: B

Question 9

The application of the Redundant Implementation pattern can help increase service
availability by establishing a duplicate deployment of a service in order to provide failover
support.

A. False B. True

Correct Answer: B

Question 10

Which of the following statements is true?

A. The Enterprise Service Bus pattern is primarily concerned with message processing
logic, while the Orchestration pattern is primarily concerned with service composition logic. B. None of these statements are true. C. The Enterprise Service Bus pattern is primarily concerned with service composition
logic, while the Orchestration pattern is primarily concerned with message processing logic. D. The Enterprise Service Bus pattern is primarily concerned with synchronous messaging
logic, while the Orchestration pattern is primarily concerned with asynchronous messaging
logic.
