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.
Your organization has decided to invest in SOA as a key component of your overall enterprise technology strategy. Identify three core benefits your organization can expect,
A. More rapid and cost-effective response to changing business needs
B. More effective reuse of macro-level business functionality
C. Automatic governance adherence
D. Immediate and significant ROI
E. Simplification of integration between existing IT assets
F. Total elimination for the need forEAI
Whether from new/changing business requirements or technical optimizations, your Services are bound to change and evolve over time. The lack of a Service versioning strategy will greatly impact the flexibility of your SOA initiative as it will severely hinder Service evolution. Which three principles should be part of a Service versioning strategy?
A. Service providers must be able to release new versions into production without waiting for consumers to certify on them.
B. A new version of a Service must be developed using the same technology (for example, Java) thatthe original Service was developed in.
C. Concurrent versions of a Service must always be deployed on the same physical server.
D. Service consumers should not require code modifications in order to access the latest
compatibleService versions.
E. Consumers must be able to test and certify on new Service versions before switching to the newversion in production.

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.
Which statement describes the purpose of a Service portfolio?
A. A Service portfolio provides a single location for storing Service meta-data, software relationships, and metrics in order to apply governance policies and systemetise reuse.
B. A Service portfolio provides a singlesoftware library from which artifacts can be deployed and versioned.
C. A Service portfolio provides a runtime view of the Services so that the right Service may be looked up and consumed in an environment.
D. A Service portfolio contains all the software artifacts that will be developed by a project so that project managers can track their lifecycle through the project.

Lack of an enterprise SOA infrastructure causes several SOA implementation challenges. What are two of the major challenges?
A. Understanding which Services are available, where they reside, their contract, invocationprotocols, and rules for use
B. Provisioning of hardware and software resources to run SOA Services
C. Managing Service versioning and Service life-cycle requirements
D. Migration of business applications to run on SOA infrastructure
You receive non-functional requirements for a set of business Services which specify that the Service must deliver secure payloads. In addition, the Services need to be built whereby they promote reusability, especially in heterogeneous IT environments. Which option best describes how you would design the Service?
A. Use Java to build the service and SSL to encrypt the transport.
B. Use Java.security to encrypt payload while making sure that service consumers are on a secure and reliable network.
C. Use WS-I to promote interoperability while using the WS-Security family of services to secure web services.
D. Use WS-Policy and WS-Reliable Messaging to support delivery-based quality of service.
While using the Service Candidate Selection Framework It becomes apparent that there is another factor specific to the organization that negatively impacts the development of Services that is not being captured by any of the existing criteria. How should this situation be handled?
A. A new realization inhibitor criterion should be added to the Parameters worksheet (and be propagated through the other worksheets) to capture and score this additional factor.
B. A new realization benefit criterion should be added to the Parameters worksheet (and be propagated through the other worksheets) to capture and score this additional factor.
C. New realization benefit and realization inhibitor criteria should be added to the Parametersworksheet (and be propagated through the other worksheets) to capture and score this additional factor.
D. This additional factor should be ignored because all of the important criteria are already included in the Service Candidate Selection Framework.
E. Replace one of the existing realization Inhibitor criterion with a new criterion that captures this additional factor.
F. Replace one of the existing realization benefit criterion with a new criterion that captures this additional factor.
