  B. Integrations should be point-to-point using Web Services.

  C. Message and data formats should be based on the native application data structures.

  D. Extensive, intrusive modifications to existing applications should be avoided.

  E. Service consumers should be able to migrate to a newer version of a SOA Service gracefully.

  F. There should not be more than one version of a SOA Service in production concurrently.

  Correct Answer: CDE

• Question 52:

  A. Implementation

  B. Interface

  C. Contract

  D. Service Agreement

  E. Business Process

  Correct Answer: BD

• Question 53:

  You receive requirements for a business Service which specifies that the Service must guarantee delivery of messages in the presence of component, system, or network failure. Which option best describes how you would design the Service?

  A. Service writes message to a fault tolerant database from which the consumer can read the message.

  B. Use WS-ReliableMessaging to support a delivery-based QoS for messages.

  C. Service posts a message on a database-backed JMS Queue from which the consumer can read the message.

  D. Use WS-Policy and WS-Security to support guaranteed delivery-based quality of service.

  Correct Answer: B

• Question 54:

  It has come to your notice that there is little or no reuse of SOA Services in production. After some

  investigation, you have been made aware that project development teams are struggling with Service

  interoperability challenges.

  What course of action do you take to address these challenges?

  A. A single registry is employed to ensure Services are consistently published.

  B. A single service engineering team is employed to build all Services which ensure implementation consistency.

  C. A single technology (for example, Java) is employed to build all Services which ensure standards consistency.

  D. Design-time governance quality points are employed to ensure that Services following agreed enterprise standards and guidelines.

  E. A single repository is employed to ensure Services are consistently discoverable.

  Correct Answer: A

• Question 55:

  What are the two key differences between SOA infrastructure and traditional infrastructure?

  A. SOA infrastructure does not need to provide monitoring and management capabilities whereas, traditional infrastructure does.

  B. The highly distributed, heterogeneous nature of SOA attempts to bring a number of disparate moving parts together, making it more complex naturally.

  C. Traditional infrastructure is based on standards, allowing you to choose from various products and vendors which are best suited to meet your requirements.

  D. Services are more granular than applications. So the infrastructure should be able to support the distribution, deployment, discovery, and management of these granular artifacts.

  Correct Answer: BD

• Question 56:

  View the exhibit to see the time invested to deliver a SOA Payment Service. What are the predicted net hours saved per consumer, assuming a consumption factor of 20% and a production investment of 200%?

  A. 41 hours

  B. 164 hours

  C. 410 hours

  D. 205 hours

  E. 328 hours

  Correct Answer: A

• Question 57:

  While analyzing the business requirements, you identify some cross-cutting functionality that does not carry any business context or have an affinity to any specific application. To which service layer classification does the Service you develop to fulfill this requirement belong?

  A. Connectivity Service

  B. Data Service

  C. Business Activity Service

  D. Utility Service

  E. Presentation Service

  Correct Answer: D

• Question 58:

  Which two statements accurately describe how the service-oriented integration architecture is deployed to physical hardware?

  A. Each layer in the architecture must be deployed to separate hardware.

  B. All layers of the architecture must be deployed to the same hardware.

  C. Multiple layers in the architecture may share hardware.

  D. All client access to the architecture must pass through the mediation layer.

  E. The Business Process layer and the Business Service layer are deployed to the DMZ tier,

  F. The Data Movement layer is deployed to the DMZ tier.

  Correct Answer: AD

• Question 59:

  One of the goals of your newly formed SOA Initiative is to address current integration brittleness and inflexibility. Which option best supports your goal?

  A. Make sure the Service contract details how the Service was implemented so that the Service consumer can take advantage of the underlying technology platform.

  B. Utilize XML because it is flexible and Service consumers can transform the Service payload easily.

  C. Decouple Service consumers from Service providers by encapsulating and abstracting the source systems behind a Service interface

  D. Utilize REST Services because they are more flexible because they are not restrained by WS* standards.

  Correct Answer: C

• Question 60:

  Which statement describes how complexity, effort, and benefit are used In the SOA Project Selection Framework?

  A. Complexity measures the number of integrations that the projectwould require. Effort measures the amount of effort that existing shared services would save for the project. Benefitmeasures the amount of additional revenue that would result from the project, A top project for inclusion would have a larger benefit and effort with a lower complexity.

  B. Complexity measures the number of integrations that the project would require. Effort measures the amount of effort that existing shared services would save for the project. Benefit measures the business benefit that would be delivered by the project. A top project for inclusion would have a larger benefit and effort with a lower complexity.

  C. Complexity measures the technical complexity of the project. Effort measures the level of effort required to complete the project. Benefit measures the amount that the project would advance the SOA maturity of the organization. A top project for inclusion would have a larger benefit than the effort.

  D. Complexity measures the technical complexity of the project. Effort measures the level of effort required to complete the project. Benefit measures the amount of business benefit that would be delivered by the project. A top project for inclusion would have a large benefit and lower complexity and effort.

  E. Complexity measures the technical complexity of the project. Effort measures the level of effort required to complete the project. Benefit measures the amount of business benefit that would be delivered by the project. A top project for inclusion would have a large benefit and an effort that is lower than the complexity.

  Correct Answer: B
