SOA Certified SOA Architect S90.08 Questions & Answers

• Question 11:

  Legacy systems often rely upon a combination of proprietary data models, proprietary data formats, and proprietary transport protocols. For this reason the Legacy Wrapper pattern is often used together with which of the following patterns?

  A. Atomic Service Transaction

  B. Service Messaging

  C. Service Broker

  D. Messaging Metadata

  Correct Answer: C

• Question 12:

  Which of the following statements is false?

  A. The Contract Centralization pattern positions the service contract as the official entry point into the service logic.

  B. The Contract Centralization pattern can impose performance overhead and requires the use of design standards.

  C. The application of the Contract Centralization pattern enables access to underlying service resources through the use of secondary or unofficial technical contracts.

  D. The Decoupled Contract pattern supports the application of the Contract Centralization pattern.

  Correct Answer: C

• Question 13:

  The service model most associated with the Process Abstraction and Orchestration patterns in general is:

  A. entity service

  B. utility service

  C. wrapper service

  D. None of the above.

  Correct Answer: D

• Question 14:

  The application of the Contract Centralization pattern requires that runtime access policies be implemented.

  A. True

  B. False

  Correct Answer: B

• Question 15:

  When applying the Asynchronous Queuing pattern you aim to establish an environment in which:

  A. an intermediate buffer exists between a service and its service consumer

  B. temporary message storage is provided in case either the service or service consumer are unavailable

  C. periodic re-transmission of a message is supported until it is successfully delivered

  D. enforcement of consistent, uninterrupted, synchronous communication between service and service consumer are guaranteed

  Correct Answer: ABC

• Question 16:

  Because the Process Abstraction pattern advocates the abstraction of logic, its application helps filter out logic in support of defining services.

  A. agnostic, atomic, agnostic

  B. non-agnostic, business, agnostic

  C. non-agnostic, agnostic, agnostic

  D. agnostic, rules-related, non-agnostic

  Correct Answer: C

• Question 17:

  Service logic can be deployed in isolation to autonomy, but services can still autonomy when they are required to access shared data sources.

  A. increase, gain

  B. decrease, gain

  C. increase, lose

  D. decrease, lose

  Correct Answer: C

• Question 18:

  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.

  Correct Answer: C

• Question 19:

  The application of which pattern can address inconsistent service behavior exhibited when a service is required to access a shared database with inconsistent performance?

  A. Stateful Services

  B. Atomic Service Transaction

  C. Service Data Replication

  D. Asynchronous Queuing

  Correct Answer: C

• Question 20:

  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.

  Correct Answer: D
