• Question 11:

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

  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.

• Question 13:

  The application of the Intermediate Routing pattern relies on the use of service agents. In order for the pattern to be applied properly, these service agents must be active in that they must change data within the message as part of their routing functionality.

  A. True
  B. False
  B. False

• Question 14:

  The use of service agents will affect the design of service compositions as follows:

  A. it will tend to increase the number of required services
  B. it will tend to decrease the number of required services
  C. it will tend to increase the number of required service compositions
  D. it will tend to decrease the number of required service compositions
  B. it will tend to decrease the number of required services

• Question 15:

  Which of the following is not required for an atomic service transaction to be successfully carried out?

  A. participating services need to capture a snapshot of current data prior to making changes to it
  B. a transaction management system that coordinates the actions of participating services
  C. transaction participants need to be limited to atomic service agents
  D. transaction participants must be able to commit changes or rollback uncommitted changes
  C. transaction participants need to be limited to atomic service agents

• Question 16:

  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
  A. redundantly deployed services
  C. compositions that compose redundantly deployed services

• Question 17:

  A. event management program
  B. synchronous queue
  C. event-driven Web service
  D. database
  A. event management program

• Question 18:

  Which of the following statements about the subscriber role established by the application of the Event-Driven Messaging pattern is true?

  A. a service can have multiple consumers as subscribers
  B. a consumer can only subscribe to one service
  C. a service can only have one consumer as a subscriber
  D. All of these statements are true.
  A. a service can have multiple consumers as subscribers

• Question 19:

  When applying the Policy Centralization pattern, if you create a global policy that conflicts with a service-specific policy that you already had in place, then:

  A. you did not correctly apply the Policy Centralization pattern, because it guarantees policy conflict resolution
  B. you need to apply the Intermediate Routing pattern in order to allow messages to avoid one or the other policy
  C. you need to apply the Decoupled Contract pattern in order to separate the conflicting policy definitions
  D. None of the above.
  D. None of the above.

• Question 20:

  The Invoice service in an accounting firm is heavily reused by different service compositions. The owners of the service decide to protect its integrity by disallowing access to any part of its underlying implementation and further want to avoid the risk of having this service create a single point of failure. Which two patterns should they apply in order to accomplish this goal?

  A. Contract Centralization, Decoupled Contract
  B. Domain Inventory, Redundant Implementation
  C. Data Model Transformation, Service Data Replication
  D. Contract Centralization, Redundant Implementation
  D. Contract Centralization, Redundant Implementation
