SOA Certified Professional Advanced SOA Design & Architecture Sample Questions:

1. The Reliable Messaging pattern requires:

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

2. One SOA type can inherit the features and limitations of another SOA type with a broader scope. For example, the environment and conventions established by the service-oriented enterprise architecture can be carried over into individual service inventory architectures.

A) True
B) False

3. Which of the following statements accurately describes the difference between the Atomic Service Transaction pattern and the Compensating Service Transaction pattern?

A) All of the above.
B) The Atomic Service Transaction pattern provides support for the rollback of changes, whereas the Compensating Service Transaction pattern does not.
C) The Atomic Service Transaction pattern does not rely on pre-defined alternative exception handling logic, whereas the Compensating Service Transaction pattern does.
D) The Atomic Service Transaction pattern is more suitable in situations that require real-time activity processing, whereas the Compensating Service Transaction pattern is more suitable for long-running activity processing.

4. 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 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.
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 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.
D) None of the these statements describe solutions that directly solve this problem.

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