SOA Advanced SOA Design & Architecture Set 2

1.

A service composition architecture with the following requirements needs to be created: 1. Services will have different periods of availability. 2. Sometimes the destination of a message cannot be determined until runtime. 3. All the services do not support the same messaging protocol. Of the following choices, which patterns should be used to address these requirements?

Event-Driven Messaging, Intermediate Routing, Atomic Service Transaction Protocol Bridging, Compensating Service Transaction, Asynchronous Queuing Intermediate Routing, Data Format Transformation, Asynchronous Queuing Protocol Bridging, Intermediate Routing, Asynchronous Queuing

2.

Which of the following statements is true?

Enterprise service bus products commonly provide data model transformation features. Orchestration products commonly provide data model transformation features. The Service Broker compound pattern includes the Data Model Transformation pattern. All of these statements are true.

3.

When applying the Process Abstraction and Process Centralization patterns together, non-agnostic business process logic is:

located in one place and separated from agnostic logic distributed across multiple locations and separated from agnostic logic located in one place and combined with agnostic logic distributed across multiple locations and combined with agnostic logic

4.

The Process Centralization pattern is a part of which compound pattern?

Enterprise Service Bus Orchestration Federated Endpoint layer Official Endpoint layer

5.

The Process Centralization pattern is most commonly associated with which service model?

utility service entity service task service hybrid service

6.

The Process Centralization pattern:

physically centralizes business process logic into a single location logically centralizes business process logic into a separate service layer physically centralizes task services into an enterprise service bus logically centralizes task services into an enterprise service bus

7.

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

8.

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

Up-front analysis effort is required to establish a schema layer independent of and in support of the service layer. Schemas can be designed and implemented independently from the service capabilities that utilize them. Multiple technical service contracts can make reference to a single schema. Services in the same service inventory cannot share the same schemas.

9.

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

10.

Which of the following statements are false?

The application of the Policy Centralization pattern decreases the governance burden required to ensure that common policies are kept synchronized over time. The application of the Policy Centralization pattern increases the amount of policy content in the service inventory. The application of the Policy Centralization pattern combines global and domain-specific policies into a single location. As a result, the distinction between aglobal and domain policy is eliminated. The application of the Policy Centralization pattern requires that policies only be expressed with the WS-Policy standard.
