SOA S90-08A Online Questions & Answers

• Question 91:

  Which of the following statements is true?

  A. Although the Logic Centralization pattern addresses the question of how to avoid redundant service logic, it does not address how the logic should be accessed.
  B. The Contract Centralization pattern specifies how to access a service through its published contract, but it does not indicate which services should be accessed for specific purposes.
  C. When the Logic Centralization and Contract Centralization patterns are applied together, they realize the Official Endpoint pattern because they effectively establish an official endpoint for a service.
  D. All of these statements are true.
  D. All of these statements are true.

• Question 92:

  The application of the Intermediate Routing pattern can result in multiple service agents intercepting a message before it arrives at its destination.

  A. True
  B. False
  A. True

• Question 93:

  Which statement regarding intermediate routing is true?

  A. The application of the Intermediate Routing pattern is suitable for handling message routing requirements that are dynamic in nature and difficult to anticipate in advance.
  B. The application of the Intermediate Routing pattern is suitable for handling pre- determined message paths with fixed routing requirements that cannot be changed at runtime.
  C. The application of the Intermediate Routing pattern tends to improve runtime performance when compared to an approach whereby routing logic is embedded within individual services.
  D. None of these statements are true.
  A. The application of the Intermediate Routing pattern is suitable for handling message routing requirements that are dynamic in nature and difficult to anticipate in advance.

• Question 94:

  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 synchronous messaging logic, while the Orchestration pattern is primarily concerned with asynchronous messaging logic.
  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. None of these statements are 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.

• Question 95:

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

  A. True
  B. False
  A. True

• Question 96:

  Which pattern aims to increase the autonomy of a service specifically via the use of a replicated database?

  A. Redundant Implementation
  B. Stateful Services
  C. State Repository
  D. None of the above.
  D. None of the above.

• Question 97:

  Which of the following functions would not be suitable for a typical service agent?

  A. event logging
  B. message routing
  C. complex Web service composition
  D. error logging
  C. complex Web service composition

• Question 98:

  Which of the following statements is true?

  A. The overuse of service agents can lead to dependencies on proprietary vendor platforms.
  B. The use of service agents is limited to the service architecture.
  C. Service agents are common in orchestration environments but not within enterprise service bus environments.
  D. None of these statements are true.
  A. The overuse of service agents can lead to dependencies on proprietary vendor platforms.

• Question 99:

  The Process Abstraction pattern can help solve which of the following problems?

  A. When business process logic is physically distributed across independent service implementations, it can be difficult to extend and evolve due to its decentralized nature.
  B. The same business rules may exist within different business-centric services, leading to redundancy issues and governance problems due to the challenge of maintaining consistent rule logic within multiple services as rules changes over time.
  C. Grouping non-agnostic business logic together with agnostic business logic hinders the governance of the non-agnostic logic and the reuse of the agnostic logic.
  D. Bundling both messaging and validation logic into the same service eventually results in the creation of redundant logic across multiple services, thereby causing performance challenges.
  C. Grouping non-agnostic business logic together with agnostic business logic hinders the governance of the non-agnostic logic and the reuse of the agnostic logic.

• Question 100:

  A typical service-oriented enterprise architecture specification can encompass:

  A. only one service inventory
  B. multiple service inventories
  C. non-service-oriented technology architectures
  D. None of the above.
  B. multiple service inventories
