The SOA infrastructure you are building requires dynamic Service binding for loose coupling and a standards based way of storing and accessing Service descriptions at run time. How will you Implement this with Oracle products? Use Oracle Service Registry (OSR), which provides a robust UDDI registry for runtime metadata information including Service descriptions (WSDl), and policies (WS-Pollcy). Use Oracle BPEL Process Manager to implement dynamic Service binding functionality and SOA Service catalog Implement Service discovery and dynamic Service binding functionality using Oracle Business Process Management (OBPM) and Oracle Business Rules (OBR) products This functionality is not available in any of the Oracle products out of the box.
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? $15,750 $22,500 $225,000 $157,500 $382,500.
You are a senior architect in an organization that wishes to adopt SOA for a number of projects in the future because of agility and cost reduction benefits. Who needs to be engaged in the changes that will impact the organization and which functional units should be Involved In implementing a successful SOA initiative? The head of the IT delivery organization needs to be engaged because It is their organization that will be affected the most by this change. The business and operations will continue as before. The CIO needs to be leading this initiative as all aspects of IT need to be engaged from delivery through to operations, but business involvement can be minimised, The SOA can be built up on a project-by-project basis so each project needs to be engaged when needed. The CEO must drive this initiative because it will have far-reaching impacts for all parts of the organization. The CIO and leaders of those business units falling under the scope of the SOA initiative need to drive the changes required for SOA adoption.
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? Define like-for-like SOA organization governance structures to match your IT organization governance structures, which address only SOA concerns. 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. 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. 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.
How should business processes and technical orchestrations be handled when developing SOA Services as part of service-oriented integration architecture? Technical orchestrations are business processes that have been implemented using BPEL Business processes should be isolated from technical details by encapsulating the technical details in technical orchestrations. Activities within a business process that are likely to change due to business changes should be encapsulated in a technical orchestration. Business processes should not use any technical orchestrations. Business processes only call Business Services whereas technical orchestrations only call Connectivity Services.
One of the goals of your newly formed SOA initiative is to speed up time to market for new and updated functionality. Which option best supports your goal? Utilize Service composition to reuse and combine existing Services to form new more course grained functionality. Utilize a common data model across all Services so that no data transformation is required when Services are reused. Only deploy SOA Governance when you have 50 or more Services. Utilize REST Services over SOAP-based Services because they are quicker to develop.
Which role is critical in promoting the discovery and reuse of SOA Services and supporting the service lifecycle? Service Development Platform Service Bus Metadata Repository Service Registry.
A successful SOA initiative is built on a solid SOA governance foundation. What three statements are true when referring to a SOA Governance model? There is one standardized SOA governance model that is appropriate for all enterprises. There is no single model of good SOA governance because each enterprise has differences andnuances. A SOA governance model focuses only on the lifecycle of a Service. Compliance with a defined SOA governance model Is automatic after It has been deployed. A SOA governance model enables the definition of policies and processes to guide management into
making effective SOA decisions. A SOA governance model enables authorized groups to encourage/enforce alignment to SOA
architecture and cultural orientation.
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? 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. 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. 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, 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. Products are not directly mapped onto the architecture; only the capabilities provided by the products are mapped onto the architecture.
Which two statements are true with respect to SOA Services? A Service must not have any dependency on the identity of the consumer that invokes it. Services should be aware of the protocol used to invoke them, where they physically exist, and on what type of hardware or operating system they run. In order for Services to be versatile and support reuse, there must be no separation of concerns in terms of what they do and how they are used. Services must not be tied to any particular physical location.
Which three statements differentiate SOA requirements from project requirements? SOA requirements are not owned by any single application, consist of their own lifecycle, and are managed independently. SOA requirements are developed iteratively with the business and mapped onto the enterprise business function model. SOA requirements have a classification that reflects the project that implemented them. SOA requirements are managed at the enterprise level. SOA requirements are concerned with the Services that deliver integration capabilities. SOA requirements are refined into project requirements.
You have identified an existing Service that you would like to re-use. You need to submit a Service consumption request. Which two items are most appropriate to put into the request? Data that you want to consume from the Service Expected load that you will put on the Service Expected usage profile, such as days of the week or hours in the day Type of client that will be connecting to the Service.
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 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. 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. 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. 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.
A consumer invokes a synchronous request/response but the service only supports asynchronous request/response. Which service infrastructure capability resolves the differences between the invocations of the consumer and provider? Transport Mediation Transformation Mediation Service Routing Message Exchange Pattern Mediation Dynamic Binding.
Which of the following statements describes how the layers in the service-oriented integration architecture interact? Upper layers in the architecture use capabilities provided by any of the lower layers in the architecture. A layer in the architecture uses capabilities provided by the adjacent layers, that Is, the layer-above and the layer below. A layer in the architecture uses capabilities provided by the adjacent lower layer in the architecture. A layer in the architecture uses capabilities provided by the adjacent upper layer in the architecture. The layers in the architecture expose functionality to the User Interaction Systems, but do not interact.
When considering the interface design for an enterprise-wide Service you have been guided by the SOA Reference Architecture to consider a document style data format first. Why is that? Large amounts of data can be exchanged with document-style interfaces. This will provide the greatest opportunity for re-use from the widest possible number of consumers. Document-style interfaces provide for tight coupling between consumers and service providers. Document-style interfaces tend to be quite fine-grained so that they can be re-composed in innovative ways. Document-style interfaces provide for tight coupling between consumers and service providers.
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 Service is a means of packaging reusable software building blocks to provide functionality to users, applications, or other Services. A Service is comprised of Implementation code and a WSDL by which it is described. A Service is only used for wrapping legacy systems to enable easier integration, A Service is an independent, self-sufficient, functional unit of work. A Service is discoverable, manageable, and measurable. A Service is a Java-based component.
What is the reason to have separate production, services, and maintenance networks in the product deployment of the service-oriented integration architecture? 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. 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. 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. 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 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.
Which two statements are true of Oracle's SOA Governance Framework? Replaces traditional governance frameworks Defines the need for principles, policies, processes, roles, and Infrastructure Contains an SOA Governance Reference Model Defines SOA Governance as a one-off project Can be fully implemented using a registry and a repository.
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? Source code Usage Agreements Capacity Metrics Security Policies Build scripts.
Whenever an account is past due, the billing system will post an "account past due" event message to a JMS queue. How is the event handled in the service-oriented integration architecture? The Business Process layer In the architecture listens for and handles the event. The Mediation layer in the architecture listens for the event and then routes the event to the appropriate SOA Service There is a JMS listener for each layer in the architecture, so each layer In the architecture Is responsible for handling events as appropriate. The architecture does not support events generated by a back-end system. The Data Movement layer in the architecture is used to detect and handle events generated by the back-end systems.
Which statement best describes SOA governance continuous improvement? SOA governance continuous improvement enables your organization to define and deploy your own focused and customized SOA initiative. SOA governance continuous improvement enables your organization to define and deploy your own focused and customized SOA governance model. SOA governance continuous improvement enables your organization to make sure that Services are reused. SOA governance continuous improvement enables your organization to achieve ROI on you SOA initiative.
One of the SOA deployment models defined by Oracle Reference Architecture is Segregated Deployment. What is Segregated Deployment? An approach for deploying services and infrastructure to support Services that have a local scope An approach to Services deployment in which Services and applications are co-deployed in a segregated environment An approach to Services deployment that promotes the separation of Services from applications and the grouping of Services with similar availability needs An approach to development where the Service development environment is isolated from the Service deployment environment.
Which two statements describe SOA Governance relationships? SOA Governance integrates with and extends IT Governance SOA Governance directly aligns with Corporate Governance SOA Governance ignores IT Governance Cloud Computing Governance dictates SOA Governance EA Governance Influences SOA Governance
.
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 other teams from creating Services. SOA Services incur greater costs over their full lifecycle than application components and therefore must justify the extra investment before they are built. No control over Service creation can result in Service proliferation resulting in a complex and inconsistent SOA that is difficult to manage and maintain. 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.
