A part of a service contract that is commonly standardized is the __________.

• A.service registry
• B.data model
• C.service agent
• D.data agent

Service-oriented analysis and service-oriented design are typical phases of an SOA delivery lifecycle.

• A.False
• B.True

Below are excerpts from four different SOA adoption strategy documents. Based on your understanding of SOA, service-orientation, and the goals of service-oriented computing, select the adoption strategy that is clearly the most likely to succeed:

• A."Each of our existing legacy applications already establishes a domain boundary that is defined by the purpose of the application. We are confident that by leveraging these pre-defined silo-based boundaries we can create a series of effective domain service inventories, each with a scope that corresponds to a legacy application boundary."
• B."Our strategy is to make the consistent application of service-orientation principles a priority in order to support the attainment of the goals of service-oriented computing. The primary justification for this approach is the fact that we have identified the goals of service-oriented computing to be in alignment with our own business goals."
• C."As part of our planned transition toward service-orientation, we will continue to extend the existing legacy applications with transformation-centric middleware that will enable seamless integration and runtime conversion between the different data models and data formats used by these applications."
• D."Our strategy fully supports the tactical (short-term) nature of service-oriented computing by de-emphasizing standardization and allowing different project teams to deliver services optimized to their respective requirements. This not only speeds the initial delivery of services, it further supports interoperability by enabling services to leverage established integration technologies."

The Universal SOA Commission (USOAC) has been standardizing the service-oriented architectural model since 1998. Their role is to regulate the marketplace to ensure that all usages of the "SOA" acronym for branding purposes are legitimate. They enforce this via product assessment and certification, a process that all of the major software vendors follow to obtain official USOAC certification.

• A.False
• B.True

Project Team Alpha delivers Service A for Solution 1. Project Team Beta delivers Service B for Solution 2. Some time later, Project Team Omega wants to reuse Service A and Service B for its new Solution 3. How would Services A and B need to have been designed in order for Project Team Omega to successfully reuse these services without having to resort to a major integration project?

• A.Services A and B need to reside on the same physical server or workstation, thereby allowing them to be reused without the need for major integration effort.
• B.Services A and B need to be standardized and designed with an emphasis on intrinsic interoperability so that they are compatible regardless of when or by which project team they are delivered.
• C.Service A needs to be designed using a different vendor platform than ServiceB. This enables vendor diversity, thereby guaranteeing interoperability.
• D.Services always require the use of transformation technologies in order to communicate. Therefore, major integration effort is unavoidable in this scenario.
