Q21. While defining yourSOA governance model, you decide to define your organization structures to define/monitor and enforce policies surrounding the enablement of your SOA initiative. After assessing your existing IT governance model, you decide that it is not appropriate for your existing organization governance model to be updated to address the needs of your SOA initiative. Therefore, you decide on which one of the following course of actions?
A. Define like-for-like SOA organization governance structures to match your IT organization governance structures, which address only SOA concerns.
B. Define new SOA organization governance structures that at a minimum must include a SOA Center of Excellence, SOA Architecture Authority, and a Service Advisory Council.
C. Define SOA organization governance structures that address the needs of your SOA initiative.The number and names of these structures are less important than the roles and responsibilities.
D. Define new SOA organization governance structures that at a minimum must include a SOA Steering Board, a SOA Center of Excellence, and a service librarian.
A key aspect of SOA Governance is the updates or creation of new governancestructures to define/monitor and enforce policies surrounding the enablement of theSOA initiative. The number and names of these structures is less important than theroles and responsibilities they encompass. The names of the structures are arbitrary asan IT steering board, IT committee, and architecture review board could all performthe duties within different enterprises.
Q22. While defining the SOA Requirements Management process, you have identified the need for a SOA repository. Which three items would you store against your Service?
A. Source code
B. Usage Agreements
C. Capacity Metrics
D. Security Policies
E. Build scripts
Q23. Which statement describes how complexity, effort, and benefit are used In the SOA Project Selection Framework?
A. Complexity measures the number of integrations that the projectwould require. Effort measures the amount of effort that existing shared services would save for the project. Benefitmeasures the amount of additional revenue that would result from the project, A top project for inclusion would have a larger benefit and effort with a lower complexity.
B. Complexity measures the number of integrations that the project would require. Effort measures the amount of effort that existing shared services would save for the project. Benefit measures the business benefit that would be delivered by the project. A top project for inclusion would have a larger benefit and effort with a lower complexity.
C. Complexity measures the technical complexity of the project. Effort measures the level of effort required to complete the project. Benefit measures the amount that the project would advance the SOA maturity of the organization. A top project for inclusion would have a larger benefit than the effort.
D. Complexity measures the technical complexity of the project. Effort measures the level of effort required to complete the project. Benefit measures the amount of business benefit that would be delivered by the project. A top project for inclusion would have a large benefit and lower complexity and effort.
E. Complexity measures the technical complexity of the project. Effort measures the level of effort required to complete the project. Benefit measures the amount of business benefit that would be delivered by the project. A top project for inclusion would have a large benefit and an effort that is lower than the complexity.
Q24. After having success in your SOA initiative across a single line of business, management wants you to deploy SOA across the enterprise in a cost effective and expedited manner. Your primaryconcern is that not all of your organization's line of businesses has enough developers with the knowledge and experience to develop Services. Which course of action do you apply to address this concern?
A. Allow each line of business to hire external consultants to develop Services
B. Implement a shared resource service factory
C. Send all line of business developers on a service engineering course
D. Implement an enterprise service factory
Q25. IT organizations have at their disposal software assets that, If systematically reused in the transformation to a Service-Oriented Architecture, can potentially offer huge savings each year by increasing development productivity and decreasing software maintenance costs. The measurement that estimates an asset's value based on the development hours avoided by reusing rather than recreating it, is called?
A. Predicted Net Hours Saved
B. Predicted Asset Value Estimation
C. Predicted Costs Saved
D. Predicted Reuse Savings
E. Predicted Development Costs Saved
Within the confines of this focused approach, an asset'sestimated value is based on thedevelopment costs avoided by reusing rather than recreating it. That measurement isreferred to here as Predicted Net Hours Saved. By reusing existing assets, anorganization avoids both the costs of repeatedly developing the same functionalityand the costs of maintaining different implementations of the same functionality.Reuse consolidates functionality and reduces redundancy. The more that reuse occurs,the greater the savings.
Q26. Which statements describe how the Mediation Layer relates to the other architecture layers In the service-oriented integration architecture?
A. The Mediation Layer facilitates communication between layers in the architecture and between the architecture and the systems that connect to the architecture.
B. The Mediation Layer provides the bulk data movement capability for the architecture.
C. The Mediation Layer enables connectivity to back-end systems by providing protocol mediation.
D. Every call between layers in the architecture must pass through the Mediation Layer.
E. The Mediation Layer provides the data translations needed to convert all Data Services data formats to the normalized data format.
Q27. One of the goals of your newly formed SOA initiative is for business persons to support business-level service composition. Which option best supports your goal?
A. Services must include a formal contract that specifies the functional and non-functional capabilities provided.
B. Employ a Service naming strategy that details what functionality the Service delivers.
C. Deploy a Service Repository that classifies Services by the name of the back-end system where the implementation code resides.
D. Assign a Business Architect from the SOA COE to support a group of business persons.
Q28. With an hourly burden rate of $100 and at least 7 opportunities for reuse, what is the potential reuse monetary value of a SOA Service that has a predicted net hours saved of 225 hours?
Q29. Over the past several years, change requests from lines of business (LOB) have increased significantly. Your IT department is having a hard time addressing this increase in requests, due to their time to market requirements and the time it takes for all affected lines of business to perform testing on the new/updated functionality. How can SOA be best utilized to address your challenge?
A. To address common functional requirements, each LOB is allocated their own Business Activity Service. This has the advantage that when a LOB Business Activity Service is updated only a single LOB is affected.
B. The service infrastructure can provide the ability to mediate and stage the deployment of multiple versions of a Service which will allow multiple versions of a Business Activity Service to be available at run time. This enables different LOB consumers to access different versions of the Service.
C. Each LOB is allocated their own Presentation Service. This has the advantage that each LOB consumer can have a different user experience from other LOB consumers and have the ability to hide the new/updated functionality.
D. Each LOB utilizes a separate service infrastructure environment. Service configurations can be propagated between environments, allowing different LOB consumers to access different Services that address the same functionality.
Q30. Which three statements differentiate SOA requirements from project requirements?
A. SOA requirements are not owned by any single application, consist of their own lifecycle, and are managed independently.
B. SOA requirements are developed iteratively with the business and mapped onto the enterprise business function model.
C. SOA requirements have a classification that reflects the project that implemented them.
D. SOA requirements are managed at the enterprise level.
E. SOA requirements are concerned with the Services that deliver integration capabilities.
F. SOA requirements are refined into project requirements.
