Q31. You have been asked to justify the creation of a Service, but skills In the best implementation technology are expensive. How would you reflect that in the Service Candidate Selection Framework? 

A. Choose a different technology and automatically score the Service as having a high technology capability inhibitor score 

B. Reflect the cost of the resources in the weighting for the skill set Impact inhibitor score 

C. Reduce the potential reuse level of the Service because It may be difficult to find skills to update and manage the Service in the future 

D. You cannot score this Service without the skills being available 

E. This availability of the skill is too subjective to be possible to score 

Answer:


Q32. 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.

Q33. A key aspect of your SOA initiative includes a clear and consistent definition of a service. Which three statements are true in Oracle's definition of a Service? 

A. A Service is a means of packaging reusable software building blocks to provide functionality to users, applications, or other Services. 

B. A Service is comprised of Implementation code and a WSDL by which it is described. 

C. A Service is only used for wrapping legacy systems to enable easier integration, 

D. A Service is an independent, self-sufficient, functional unit of work. 

E. A Service is discoverable, manageable, and measurable. 

F. A Service is a Java-based component. 

Answer: A,D,E 

Explanation: 

A Service is a means of packaging reusable software building blocks to providefunctionality to users, applications, or other Services; it is an independent,self-sufficient, functional unit of work that is discoverable, manageable, measurable,has the ability to be versioned, and offers functionality that is required by a set ofconsumers. A Service may be shared, which means that the function offered by theService is intended for multiple consumers, some known, and others that have not yetbeen identified.

Q34. 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. 

Answer: B,C,E 


Q35. A unit test case aims to test two of the components from the Service model. What are these components? 

A. Implementation 

B. Interface 

C. Contract 

D. Service Agreement 

E. Business Process 

F. Composite Service 

Answer: B,D 


Q36. Which two statements accurately describe how the service-oriented integration architecture 

is deployed to physical hardware? 

A. Each layer in the architecture must be deployed to separate hardware. 

B. All layers of the architecture must be deployed to the same hardware. 

C. Multiple layers in the architecture may share hardware. 

D. All client access to the architecture must pass through the mediation layer. 

E. The Business Process layer and the Business Service layer are deployed to the DMZ tier, 

F. The Data Movement layer is deployed to the DMZ tier. 

Answer: A,D 


Q37. Business functional modellingis useful for modelling organizations that wish to adopt SOA. Select the three statements below that describe the benefits of business functional modelling to SOA. 

A. A business functional model assists in minimizing functional duplication. 

B. A business functional model provides a holistic view of the enterprise to avoid leaving gaps in theanalysis. 

C. A business functional model progresses from fine to coarse-grained analysis which helps identify high value services. 

D. A business functional model is dependent on the organizational structure, 

E. A business functional model progresses from coarse to fine-grained analysis which helps identifyunique services that can be turned into coarse-grained services through composition. 

Answer: A,B,E 


Q38. Oracle Enterprise Repository (OER) provides several key capabilities of SOA Infrastructure. Select two capabilities provided by Oracle Enterprise Repository. 

A. Policy enforcement - enforce policies through gateways (self-contained modules) and agents (interceptors) 

B. Dependency analysis - the ability to navigate taxonomies and asset relationships to facilitate Impact analysis based on Inter-dependency 

C. Service discovery - facilitates Service discovery by providing a means to locate potential Serviceseither through taxonomy navigation, or direct search 

D. Performance management - measures and monitors the availability and performance of Services for historical trending, troubleshooting, and root cause analysis purposes 

Answer: B,D

Q39. Which two statements are valid SOA infrastructure principles? 

A. SOA infrastructure must be designed to enable point-to-point integration. 

B. SOA Infrastructure must support all Services with standards-based interfaces, regardless of their choice of implementation technology. 

C. SOA Infrastructure must be based on open standards. This supports a best-of-breed approach and prevents vendor lock in. 

D. Multiple versions of a SOA Service must not be run concurrently. 

Answer: B,C

Q40. A project manager has come to you as the SOA architect asking why his Service Candidate has to be justified before he can build it. What two reasons are you going to give that it is important that Services must be justified before they are implemented? 

A. The Services must be implemented by a single team and the Justification process prevents otherteams from creating Services. 

B. SOA Services incur greater costs over their full lifecycle than application components and therefore must justify the extra investment before they are built. 

C. No control over Service creation can result in Service proliferation resulting in a complex and inconsistent SOA that is difficult to manage and maintain. 

D. The release of the Service needs to be co-ordinated with other projects and therefore his project will not be delivering it because the timescales are incompatible. 

Answer: C,D
