Question 10

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

Accepted Answer

Contract Centralization ensures that the service's interface is the only access point, protecting its implementation. Redundant Implementation prevents a single point of failure by having multiple instances of the service.

Question 11

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.

Accepted Answer

Services in the same service inventory can share the same schemas, which is a key aspect of the Schema Centralization pattern.

Question 12

Technical service contracts that use the same XML schemas will support the exchange of messages based on the same data models.

Accepted Answer

Technical service contracts using the same XML schemas ensure that the data structure and format are consistent, allowing for seamless message exchange based on the same data models.

Question 13

In order to realize the failover support provided by the application of the Redundant Implementation pattern, the Intermediate Routing pattern also needs to be applied so that services can be load balanced.

Accepted Answer

The Redundant Implementation pattern focuses on providing failover support by deploying multiple instances of a service, while the Intermediate Routing pattern is not a requirement for load balancing in this context. Load balancing can be achieved through other means without necessarily applying the Intermediate Routing pattern.

Question 14

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.

Accepted Answer

All the statements are true as they describe aspects of the Policy Centralization pattern, including runtime compliance checks, the importance of a policy framework, and potential issues with proprietary formats.

Question 15

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

Accepted Answer

The Schema Centralization pattern involves having a single, centralized schema that multiple services can depend on, ensuring consistency and reducing redundancy across services.

Question 16

The Process Centralization pattern:
A) physically centralizes business process logic into a single location
B) logically centralizes business process logic into a separate service layer
C) physically centralizes task services into an enterprise service bus
D) logically centralizes task services into an enterprise service bus

Accepted Answer

The Process Centralization pattern physically centralizes business process logic into a single location.

Question 17

The Asynchronous Queuing pattern can be combined with the Event-Driven Messaging pattern to allow a service consumer acting as a subscriber to receive all event notification messages that are broadcast, even those that are sent when the service consumer is unavailable.

Accepted Answer

The Asynchronous Queuing pattern can store messages in a queue, allowing the service consumer to receive them later, even if it was unavailable when the messages were initially broadcast.

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.

Accepted Answer

The Enterprise Service Bus pattern is primarily concerned with message processing logic, while the Orchestration pattern is primarily concerned with service composition logic.

Question 20

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.

Accepted Answer

B is false because centralizing policies does not inherently increase the amount of policy content; it organizes existing policies. C is false because centralization does not eliminate the distinction between global and domain-specific policies; it merely consolidates them. D is false because the Policy Centralization pattern does not mandate the use of WS-Policy; other standards can be used.
