SOA Certified SOA Architect S90.08 Questions & Answers

• Question 21:

  The application of the Redundant Implementation pattern helps increase the autonomy of:

  A. redundantly deployed services

  B. service agents that perform load-balanced access to services that are not redundantly deployed

  C. compositions that compose redundantly deployed services

  D. core service logic contained within services that do not rely on the redundantly deployed service

  Correct Answer: AC

• Question 22:

  Which of the following statements are true?

  A. The Redundant Implementation pattern is most useful for services that possess non- agnostic service logic.

  B. The Redundant Implementation pattern is concerned with eliminating single point of failure problems associated with services that are actively reused.

  C. The Redundant Implementation pattern can be supplemented with the Intermediate Routing pattern, which can be applied to load balance access to a redundantly deployed service.

  D. The Redundant Implementation pattern addresses issues of scalability, not issues of availability.

  Correct Answer: BC

• Question 23:

  The Service Fa?ade pattern is often applied in order to separate the from the underlying service implementation so that they can evolve independently.

  A. service agent

  B. service contract

  C. service activity

  D. None of the above.

  Correct Answer: B

• Question 24:

  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

  Correct Answer: A

• Question 25:

  Which of the following represent common types of logic that can be placed within a service fa?ade component?

  A. Behavior correction logic used to compensate for changes in the behavior of the core service logic.

  B. Protocol bridging logic that dynamically converts from one transport protocol to another at runtime.

  C. Relaying logic that simply relays input and output messages to and from the core service logic.

  D. Transformation logic that performs runtime data model or data format conversion.

  Correct Answer: ABCD

• Question 26:

  The Service Fa?ade pattern can be used to introduce a logic layer that resides between the and an underlying .

  A. core service logic, database

  B. core service logic, resource

  C. core service logic, legacy system

  D. All of the above.

  Correct Answer: D

• Question 27:

  Official Endpoint is a compound pattern that is comprised of the Logic Centralization pattern and the Contract Centralization pattern.

  A. True

  B. False

  Correct Answer: A

• Question 28:

  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.

  Correct Answer: D

• Question 29:

  By applying the Service Broker compound pattern, you establish an environment capable of carrying out which of the following patterns?

  A. Data Model Transformation

  B. Data Format Transformation

  C. Transaction Protocol Transformation

  D. Policy Transformation

  Correct Answer: AB

• Question 30:

  For a given service inventory architecture you would choose between an enterprise service bus product or an orchestration product, but you would not use both together.

  A. True

  B. False

  Correct Answer: B
