Q11. One of the SOA deployment models defined byOracle Reference Architecture is Segregated Deployment. What is Segregated Deployment?
A. An approach for deploying services and infrastructure to support Services that have alocalscope
B. An approach to Services deployment in which Services and applications are co-deployed in a segregated environment
C. An approach to Services deployment that promotes the separation of Services from applications and the grouping of Services with similar availability needs
D. An approach to development where the Service development environment is isolated from the Service deployment environment
Answer: C
Explanation:
The approach, recommended by Oracle, to Services deployment isthe separation ofServices from applications and the grouping of Services with similar availabilityneeds. To accomplish this, projects must be logically divided into shared andnon-shared parts. The shared parts become Services, while the non-shared partsbecome ordinary applications. Development of these assets can be done by the sameteam; however it is important that they are constructed in a way that allows them to bedeployed separately.
Q12. ORRECT TEXT
One of the goals of your newly formed SOA initiativeis to speed up time to market for new and updated functionality. Which option best supports your goal?
A) Utilize Service composition to reuse and combine existing Services to form new more
course grained functionality.
B.Utilize acommon data model across all Services so that no data transformation is
required when Services are reused.
C.Only deploy SOA Governance when you have 50 or more Services.
D.Utilize REST Services over SOAP-based Services because they are quicker to develop.
Answer: A
Q13. You have been tasked with designing a “get account” SOA Service. The source data for the service resides in a legacy system that is only accessible via MQ-Series request and response queues. The service consumers have requested a synchronous interface. What integration pattern should the SOA Service employ and why?
A. The SOA Service should implement an asynchronous "get account" method because that matches the legacy system access provided.
B. The SOA Service should implement a synchronous "get account" method because that Is what the service consumers have requested. A new synchronous Interface to the legacy system should be created.
C. The SOA Service should implement two synchronous methods. The first method is a "send account request" and the second method is a "get account response." This meets the synchronous interface request of the service consumers while matching the existing interface to the legacy system.
D. The SOA Service should implement a synchronous "get account" method because that is what the service consumers have requested. The SOA Service should use the synchronous-to-asynchronous bridging pattern and use the existing interface to the legacy system.
E. The SOA Service should implement a synchronous "get account" method because that is what the service consumers have requested. The SOA Service should use the store-and-forward pattern and use the existing interface to the legacy system.
Answer: B
Q14. It has come to your notice that your organization is suffering from service sprawl whereby, duplicate services exist in production. After some Investigation you have come to the conclusion that your existing SOA Services are not classified and therefore, making Service Discovery challenging. Which initial classification scheme should you utilize to classify your SOA Services?
A. Organizational Model
B. Technology Vendor
C. Business Functional Model
D. Reference Architecture Service Layer
E. Reference Architecture Capability
Answer: A
Q15. 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
Q16. When undertaking the Service re-use validation process, which three of the following aspects of the Service should be taken into consideration?
A. Service capacity
B. Non-functional qualities
C. Security policies
D. Servicedesign
E. Service ownership
Answer: A,C,D

Q17. You work in a highly regulated industry. Regulatory and security requirements are changing constantly. But your current enterprise application development platform Is burdensome when updating solutions to cater for these regulatory and security requirements. How can SOA be best utilized in addressing your challenge?
A. A set of regulatory and security Services can be developed that addresses all of the requirements. These regulatory and security Services can then be consumed by Business Activity Services. This allows updated regulatory and security functionality to be automatically applied to all Business Activity Services.
B. Each solution codes its own regulatory and security functionality. This functionality can then be service-enabled so that other solutions can consume it. This allows for reuse of regulatory and security functionality.
C. Utilize a policy-driven service infrastructure to decouple regulatory compliance checks and security policies from the Service implementation. This allows for a more centralized and dynamic change control.
D. Regulatory and security functionality are implemented as a set of database stored procedures. As Services are consumed, the service bus executes the relevant stored procedures and applies them to the service payload. This allows for a centralized control environment while utilizing a mature technology to apply regulatory and security functionality.
Answer: C
Q18. An IT organization already has a mixture of products that they are using for their application integrations. They want to map their products onto the service-oriented integration architecture. What guidance do you give them for accomplishing this task?
A. The capabilities in a product are identified and then the product is mapped to the architecture based on those capabilities. A product can map to more than one layer of the architecture.
B. The capabilities in a product are identified and then the product mapped to the architecture based on those capabilities. The product is mapped to the layer of the architecture where the most capabilities lie.
C. A product is compared to the Oracle products that are already mapped onto the architecture. The product is mapped onto the architecture as a replacement for the most similar Grade product,
D. A product is compared to the Oracle products that are already mapped onto the architecture. If the product provides all the capabilities of an Oracle product, the product replaces that Oracle product.
E. Products are not directly mapped onto the architecture; only the capabilities provided by the products are mapped onto the architecture.

Q19. After executing your SOA initiative for a year and deploying fourSOA projects In production, It has come to your attention that Services in production are only being consumed by the original Service producers.
What course of action do you take to address your challenge?
A. Implement a service consumption review process whereby solutions are monitored for appropriate Service reuse
B. Change the current waterfall software development approach to an agile approach to increase service consumption
C. Make all Services generic so that they are applicable to all current and future projects
D. Perform service harvesting on the four completed solutions
E. Communicate to your project teams to consume more Services

Q20. What is the reason to have separate production, services, and maintenance networks in the product deployment of the service-oriented integration architecture?
A. The separate networks provide the necessary bandwidth to support the architecture. Theproduction network is used exclusively by the applications in production. The service network is used exclusively for calling SOA Services- The maintenance network is dedicated to providing administration servers and operations terminals access to control applications, services, and Infrastructure.
B. The separate networks provide the necessary bandwidth to support the architecture. Theproduction network Is used exclusively by the applications in production. The service network is used to test SOA Services before moving them to production. The maintenance network is used exclusively to perform maintenance tasks on the production applications, services, and infrastructure.
C. The separate networks provide the necessary security to support the architecture. The production network is connected to the intranet and internet. The service network provides connectivity to the SOA Services but no access to the internet. The maintenance network is dedicated to providing administration servers and operations terminals access to control applications, services, and infrastructure.
D. The separate networks separate different types of network traffic. The production network Is used exclusively by the systems in production. The service network is used to test SOA Services before moving them to production. The maintenance network is dedicated to providing administration servers and operations terminals access to control applications, services, and infrastructure in production and test
E. The separate networks separate different types of network traffic. The production network connects to the existing production environment and provides access to the service discovery and to the service bus. The service network provides connectivity between the service bus and SOA Services only; thereby preventing service consumers from bypassing the service bus. The maintenance network is dedicated to providing administration servers and operations terminals access to control applications, services, and infrastructure.
