IBM SOA Fundamentals [2008] Set 1

1.

How can disparate services communicate with each other in an SOA?

Use XML messages to provide interoperability. Service providers adopt one common data model for all services. Enforce a common data model at the Enterprise Service Bus (ESB) layer. Business analysts create the integration logic details to negotiate between services.

2.

What does the information in the service registry support?

The complete service lifecycle Runtime lookup of service endpoints Enhances messages through mediation Transformation of messages between different technologies

3.

In the context of SOA and Business Process Management (BPM), what demonstrates flexibility in a business process?

Tasks can be rearranged without impact to the user. Business rules can be dynamically stopped at runtime. New services can be built at runtime without any special tooling. Business processes can be automated so they do not require feedback.

4.

A company has implemented a number of business processes using SOA services. How do they determine if their new processes are helping the organization to achieve its business objectives?

They establish a Center of Excellence (CoE) to monitor and report on the SOA servicesperformance. They contact a third party to analyze and evaluate the new processes against the businessobjectives. They set and monitor Key Performance Indicators (KPIs) to track performance against thebusinessobjectives. They model the new processes in a business model simulator to identify bottlenecks andpotentialperformance issues.

5.

In which situation would a manufacturing plant most likely choose to use an SOA approach for their Customer Order Analysis and Tracking System?

The company wanted development and operations to be as simple as possible. The company wanted to break down department silos and encourage everyone to use thesame set oftools. Most of the company's processes were manual or document-centric with little opportunityforautomation. The legacy system had grown in such a way that it was not easy to update and could nothandle theemerging business demands.

6.

What does the SOAP specification define?

A format for XML messaging An interface to a business process An Internet communications protocol The payload contents for a Web service message

7.

What is contained in an SOA repository as opposed to a registry?

Service policy information Versions of software components Uncommitted transactions to enable compensation handling Service endpoint information to facilitate dynamic binding at runtime

8.

Which three characteristics of services indicate a mature SOA environment?

Services are discoverable. Services use Web 2.0 technology. Services are exposed by an Enterprise Service Bus (ESB). Services are composed into broader business functionality. Services contain logic to provide compatibility across technologies.

9.

What is a role of an Enterprise Service Bus (ESB) in SOA management?

To provide the governance of services by limiting who can access services To provide point-to-point connection of service consumers and service providers To provide flexibility that allows business process inefficiencies to be rapidly corrected To ensure a seamless flow of information from anywhere at any time using a variety ofprotocols

10.

Organizations that do not adopt SOA will experience which outcome?

The adoption of Web 2.0 technologies will be more problematic. Outsourcing non-core business functions will become impractical. The potential value of existing IT assets will not be fully realized. The implementation of Web services to handle real-time transactions will not be possible.
