• Question 41:

  Which of the following is not a common impact of applying the Rules Centralization pattern?

  A. Access to a single rules service can create a processing bottleneck.

  B. An increase in performance demands due to the need to access and evaluate business rules at runtime.

  C. Conflicts when also applying the Decoupled Contract pattern.

  D. The need to adopt a business rules management product, which can create dependencies on vendor-specific technology.

  Correct Answer: C

• Question 42:

  With the Rules Centralization pattern, business rules are:

  A. retrieved and applied at runtime

  B. distributed across multiple business-centric services

  C. expressed and centralized in policies

  D. All of the above

  Correct Answer: A

• Question 43:

  Which of the following statements are true?

  A. The application of the Rules Centralization pattern centralizes the governance of business rules so that they can be modified and evolved from a single location.

  B. The application of the Rules Centralization pattern reduces redundancy by centralizing common business rules-related logic that would normally be distributed across multiple services.

  C. The application of the Rules Centralization pattern results in centralized business rules that can be applied at runtime.

  D. The application of the Rules Centralization pattern can lead to a decrease in autonomy because it can introduce the need for an additional service to be part of service compositions.

  Correct Answer: A

• Question 44:

  The application of the Rules Centralization pattern achieves the of business rules data within an inventory, but it also business logic associated with business-centric services.

  A. centralization, centralizes

  B. decentralization, centralizes

  C. decentralization, decentralizes

  D. centralization, decentralizes

  Correct Answer: D

• Question 45:

  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.

  Correct Answer: D

• Question 46:

  Which of the following is a common problem associated with the application of the Policy Centralization pattern?

  A. Changes to a shared policy definition can affect all services that rely upon it, which in turn, can affect all service consumers that have formed dependencies on the corresponding service contracts.

  B. Changes to a shared data model can affect all services that rely upon it, which in turn, can affect all service consumers that have formed dependencies on the corresponding service contracts.

  C. Changes to a shared database can affect all services that rely upon it, which in turn, can affect all service consumers that have formed dependencies on the corresponding service contracts.

  D. None of the above.

  Correct Answer: A

• Question 47:

  Which of the following statements about the application of the Policy Centralization pattern is true?

  A. Service agents can check for policy compliance at runtime.

  B. A policy framework that supports both the definition of policies and their consistent runtime enforcement is essential to meeting the goals of the Policy Centralization pattern.

  C. Enterprise service bus products sometimes use proprietary policy formats which can lead to vendor lock-in and incompatibilities with other enterprise service bus products.

  D. All of these statements are true.

  Correct Answer: D

• Question 48:

  When applying the Schema Centralization pattern, multiple services can form dependencies on the same centralized schema.

  A. True

  B. False

  Correct Answer: A

• Question 49:

  Which of the following statements are false?

  A. The application of the Policy Centralization pattern decreases the governance burden required to ensure that common policies are kept synchronized over time.

  B. The application of the Policy Centralization pattern increases the amount of policy content in the service inventory.

  C. The application of the Policy Centralization pattern combines global and domain- specific policies into a single location. As a result, the distinction between a global and domain policy is eliminated.

  D. The application of the Policy Centralization pattern requires that policies only be expressed with the WS-Policy standard.

  Correct Answer: BCD

• Question 50:

  Which of the following statements about the Schema Centralization pattern does not make sense?

  A. Up-front analysis effort is required to establish a schema layer independent of and in support of the service layer.

  B. Schemas can be designed and implemented independently from the service capabilities that utilize them.

  C. Multiple technical service contracts can make reference to a single schema.

  D. Services in the same service inventory cannot share the same schemas.

  Correct Answer: D
