• Question 4:

  Which artifact is the most helpful to an organization's SOA transformation and implementation

  roadmap?

  A. A reference architecture

  B. A service interface description

  C. A Web services standards glossary

  D. A proposed service registry document

  Correct Answer: A

• Question 5:

  How does SOA achieve alignment between business and IT?

  A. By ensuring services represent the underlying IT functions that the business must use in order to function

  B. By hiding operational details allowing services to be loosely coupled and changed to suit the situation

  C. By creating business processes that are direct representations of the business which can be simulated and refined

  D. By providing service operations that represent business tasks allowing those operations to be used in whatever combination the business decides is appropriate

  Correct Answer: D

• Question 6:

  What describes the role of the Enterprise Service Bus (ESB)?

  A. An adapter that exposes back end functionality of legacy systems

  B. A routing and mediation component that loosely couples service interfaces

  C. A routing and mediation component that loosely couples service implementations

  D. A component where transformation and aggregation are used to implement service interfaces

  Correct Answer: C

• Question 7:

  In which phase of the SOA lifecycle are service descriptions specified?

  A. Model business process and design according to requirements

  B. Construct and assemble service components

  C. Configure and deploy from test through production

  D. Manage to business and IT goals

  Correct Answer: A

• Question 8:

  What describes the purpose of the Enterprise Service Bus (ESB) in an SOA?

  A. It provides separation of concerns so that each service can be managed separately.

  B. It provides a design that allows components to be changed with less impact to the consumer.

  C. It allows a service consumer to make a service request without knowing the details of the operation.

  D. It implements service functionality by integrating existing back end service functionality using routing and transformation logic.

  Correct Answer: B

• Question 9:

  What most accurately describes a business process?

  A. The steps required to complete a unit of work in the optimal way

  B. An artifact used to capture the knowledge representing business requirements

  C. A flow of tasks that must be completed by systems or people in a certain order

  D. BPEL code that runs within a business process engine orchestrating the work of people and systems

  Correct Answer: C

• Question 10:

  Which two statements describe characteristics of SOA?

  A. Multiple business units host the same service to ensure maximum reuse and availability.

  B. Maximum reuse is achieved by ensuring services are generic so that the same service serves many different business tasks.

  C. Existing APIs are exposed over new technologies such as Web services and Enterprise Service Buses (ESB) to increase business flexibility and agility.

  D. Programming by contract ensures the service consumer can be unaware of the implementation details of the service provider facilitating loose coupling.

  E. Through layered abstraction over the implementation and runtime details, it is possible to provide software resources that give the right balance between reuse and specificity.
