Oracle IT Architecture SOA 2013 Essentials

Question No: 21

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?

  1. Large amounts of data can be exchanged with document-style interfaces.

  2. This will provide the greatest opportunity for re-use from the widest possible number of consumers.

  3. Document-style interfaces provide for tight coupling between consumers and service providers.

  4. Document-style interfaces tend to be quite fine-grained so that they can be re-composed in innovative ways.

  5. Document-style interfaces provide for tight coupling between consumers and service providers.

Answer: C

Question No: 22

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?

  1. 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.

  2. 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,

  3. The SOA can be built up on a project-by-project basis so each project needs to be engaged when needed.

  4. The CEO must drive this initiative because it will have far-reaching impacts for all parts of the organization.

  5. 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.

Answer: E

Question No: 23

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?

  1. Transport Mediation

  2. Transformation Mediation

  3. Service Routing

  4. Message Exchange Pattern Mediation

  5. Dynamic Binding

Answer: C

Question No: 24 CORRECT 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

Question No: 25

Question No: 26

What is the reason to have separate production, services, and maintenance networks in the product deployment of the service-oriented integration architecture?

  1. 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.

  2. 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.

  3. 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.

  4. 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

  5. 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.

Answer: A

Question No: 27

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#39;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?

  1. Allow each line of business to hire external consultants to develop Services

  2. Implement a shared resource service factory

  3. Send all line of business developers on a service engineering course

  4. Implement an enterprise service factory

Answer: A

Question No: 28

Services, Service consumer applications, and SOA Infrastructure components are instrumented to report on various events and conditions within the SOA environment at run time. The types of information they log can vary widely depending on the types of events in an organization. What are two example of these events?

  1. Business value of the Service

  2. Performance and load characteristics

  3. Service exceptions

  4. Service reuse metrics

Answer: B,C

Question No: 29

Which statement best describes the capabilities captured in the SOA maturity model?

  1. A capability describes how a feature of an Oracle product should be used within a SOA initiative.

  2. A capability describes a best practice for successful adoption/execution of SOA.

  3. A capability describes how industry standards should be applied within a SOA Initiative.

  4. A capability describes how technology should be applied for successful adoption/execution of SOA.

  5. A capability describes a pair-wise joining of technology and standards important to SOA adoption.

Answer: D

Question No: 30

What are the two key differences between SOA infrastructure and traditional infrastructure?

  1. SOA infrastructure does not need to provide monitoring and management capabilities whereas, traditional infrastructure does.

  2. The highly distributed, heterogeneous nature of SOA attempts to bring a number of disparate moving parts together, making it more complex naturally.

  3. Traditional infrastructure is based on standards, allowing you to choose from various products and vendors which are best suited to meet your requirements.

  4. Services are more granular than applications. So the infrastructure should be able to support the distribution, deployment, discovery, and management of these granular artifacts.

Answer: B,D
