SOA Certified Professional Advanced SOA Design & Architecture - S90-08A Exam Practice Test

A. False

B. True

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

B. The Enterprise Service Bus pattern is primarily concerned with synchronous messaging logic, while the Orchestration pattern is primarily concerned with asynchronous messaging logic.

C. None of these statements are true.

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

A. retrieved and applied at runtime

B. expressed and centralized in policies

C. All of the above.

D. distributed across multiple business-centric services

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.

A. common routing logic being physically centralized into a single service

B. common routing logic being removed from service logic and placed into service agents

C. common routing logic being removed from service agents and placed into a database

D. common routing logic being physically centralized into a single service composition

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

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

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

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

A. State data can be temporarily written to and then later retrieved from a dedicated state repository.

B. Caching large amounts of state data in memory negatively impacts scalability.

C. A state repository is not useful for supporting long-running service activities.

D. Database technology is typically used for the implementation of a state repository.

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

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

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

D. 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.

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

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

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

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

A. 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.

B. 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.

C. 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.

D. When business process logic is physically distributed across independent service implementations, it can be difficult to extend and evolve due to its decentralized nature.
