• Question 111:

  Which product provides the standard communication protocols (for example, HTTPS) between the Client Tier and the Service Tier as well as Message Security?

  A. Oracle platform Security Services

  B. Oracle WebCenter

  C. Application Development Framework

  D. Oracle HI IP Server

  Correct Answer: A

  Explanation:

  Oracle Platform Security Services comprises Oracle WebLogic Server's internal security framework and

  Oracle's security framework (referred to as Oracle Platform Security). OPSS delivers security as a service

  within a comprehensive, standards-based security framework. The Security Services includes

  SSL:Hypertext Transfer Protocol Secure (HTTPS) is a combination of Hypertext Transfer Protocol (HTTP)

  with SSL/TLS protocol.

  Note:Oracle Platform Security Services (OPSS) provides enterprise product development teams, systems

  integrators (SIs), and independent software vendors (ISVs) with a standards-based, portable, integrated,

  enterprise-grade security framework for Java Standard Edition (Java SE) and Java Enterprise Edition

  (Java EE) applications.

  OPSS provides an abstraction layer in the form of standards-based application programming interfaces

  (APIs) that insulate developers from security and identity management implementation details. With OPSS,

  developers don't need to know the details of cryptographic key management or interfaces with user

  repositories and other identity management infrastructures. Thanks to OPSS, in-house developed

  applications, third-party applications, and integrated applications benefit from the same, uniform security,

  identity management, and audit services across the enterprise. OPSS is the underlying security platform

  that provides security to Oracle Fusion Middleware including products like WebLogic Server, SOA,

  WebCenter, ADF, OES to name a few. OPSS is designed from the ground up to be portable to third-party

  application servers. As a result, developers can use OPSS as the single security framework for both

  Oracle and third-party environments, thus decreasing application development, administration, and

  maintenance costs.

• Question 112:

  Which statement best describes how the Oracle Reference Architecture (ORA) combines different Technology Perspectives?

  A. A Technology Perspective is a specialized view of ORA focused on a particular set of products and technology; therefore, the core ORA material represents the combination of all of the Technology Perspectives.

  B. Each Technology Perspective belongs to an Enterprise Technology Strategy. Each Enterprise Technology Strategy includes practical guidance on how to combine the strategy with other Enterprise Technology Strategies.

  C. The composition of different Technology Perspectives is accomplished via Industry Perspectives. The Industry Perspective illustrates and describes how the different Technology Perspectives apply to a particular industry vertical.

  D. The composition of different Technology Perspectives is accomplished via SOA Services. The SOA conceptual model is used to illustrate and describe how each Technology Perspective consumes and provides SOA Services.

  Correct Answer: D

  Explanation: The intent of SOA is to provide common reusable SOA Services that can be leveraged by a variety of consumers. SOA Services are made available to various types of service consumers in order to rationalize the way business functions are performed and enterprise data is managed. Its modular architecture approach promotes reuse and business agility, and the use of widely adopted technology standards improves interoperability between business solutions.

  Service consumers consist of various types of business solutions, such as BPM, EDA, MDM, BI.

  SOA Services can also act as service consumers.

  ORA provides a framework to describe how various technology perspectives are related.

  Note:The reference architecture is designed to support an expanding list of technology strategies. It is also

  important that the various technology perspectives can be easily combined since they are very much

  complementary.

  ORA embraces service orientation at the core so that services provide a consistent mechanism to expose

  and combine various technologies and the capabilities. A high-level conceptual model for SOA is used to

  illustrate how technology perspectives consume and provide SOA Services.

• Question 113:

  What best describes the best practice deployment of Metadata Repository?

  A. Every project should deploy its own dedicated Metadata Repository to ensure that the project assets are properly organized.

  B. The Metadata Repository is deployed as a single enterprise-scoped cluster to promote a single view of the enterprise.

  C. A sandbox Metadata Repository for training and testing purposes should not be deployed.

  D. The Source Code Management (SCM) server doubles as a Metadata Repository.

  Correct Answer: A

  Explanation:

  A metadata repository is used as a common repository for managing metadata of different applications.

  Many applications use the MDS repository to manage their metadata. Each deployed application uses a

  logical partition in metadata repository. This logical partition also helps in maintaining the metadata

  lifecycle. Before deploying a application, you create a partition for it in MDS repository. This command

  creates a partition with the given name in the specified repository.

  Note: The Metadata repository provides a centralized holding area for a great deal of SOA related

  information that will be utilized at design time to construct additional services and applications. The

  repository also provides the primary means for service discovery. In many ways, the service repository can

  be utilized as the center point for service oriented design.

• Question 114:

  What additional functions might an authentication service perform aside from performing basic authentication?

  A. directory management

  B. strong authentication

  C. risk profiling based on conditional factors such as time of day, device, or location

  D. initiating challengequestions based on conditional factors such as time of day, device

  E. forwarding users to password update and reset services

  Correct Answer: E

  Explanation:

  The authentication service can detect when the user's password needs to be reset or changed and redirect

  the user to a self-service management interface.

• Question 115:

  When mapping Oracle Products onto the Logical view, what is the best approach?

  A. Utilize management packs, connectors, and plug-ins to create a customized product mapping for the Logical view.

  B. Use Oracle Enterprise Manager to provide core capabilities required by the three layers for Oracle stack, and use management packs, connectors, and plug ins for non-Oracle stack.

  C. Use an Oracle Enterprise Manager product to provide all the capabilities required by the three layers in the Management and Monitoring architecture.

  D. Use a third-party to provide all capabilities required by the three layersin the Management and Monitoring architecture.

  Correct Answer: C

  Explanation:

  Oracle offers a comprehensive SOA solution through a suite of SOA products. Oracle Fusion Middleware

  products cover the needs of the SOA infrastructure end-to-end. The figure below shows the mapping of

  Oracle products to the SOA logical components.

  Management of services is extremely important in SOA environments, where services are integrated,

  reused, and constantly changed. Oracle Enterprise Manager (OEM) simplifies monitoring and managing

  SOA environments. It addresses each of the challenges by helping model, monitor, and manage the SOA

  environment.

  The products referred in the figure are:

  *

  OSB - Oracle Service Bus

  *

  OSR - Oracle Service Registry

  *

  OER - Oracle Enterprise Repository

  *

  OWSM - Oracle Web Service Management

  *

  OEM - Oracle Enterprise Manager (with SOA management pack)

  *

  IdM - Identity and Access Management

  There isn't necessarily a one to one mapping between logical architecture components and products. While some products target a specific logical need, most provide additional features, such as monitoring, management, and security.

  

  Note:

  The SOA infrastructure capabilities can be grouped into the following logical components as shown in

  Figure below.

  *

  Service Bus

  *

  SOA Security Framework

  *

  Service Registry

  *

  Metadata Repository

  *

  Monitoring Framework3-2 ORA SOA Infrastructure

  *

• Question 116:

  The Oracle Reference Architecture provides a specific definition of SOA Service. Which statement best describes the relationship between SOA Service and Web Service?

  A. A Web Service is one possible type of SOA Service.

  B. A SOA Service is a Web Service with a defined Service Contract.

  C. A SOA Service may be implemented using a Web Service Interface.

  D. All SOA Services are Web Services, but not all Web Services are SOA Services.

  E. All Web Services are SOA Services, but not all SOA Services are Web Services.

  Correct Answer: C

  Explanation: In service-oriented integration the consumer is decoupled from the source system via the SOA Service that encapsulates and abstracts the source systems behind a service interface. Consumers of the SOA Service should need no details about the underlying source system. They should base the service usage solely on the contract provided by the SOA Service. Unfortunately, simply adding a wrapper (e.g. Web service) to an existing system does not eliminate pointto-point integration. In fact point-to-point integration can be accomplished quite nicely using Web service interfaces. To be truly service-oriented, the SOA Services created must be well designed and constructed so the source system details do not bleed through. Service infrastructure that provides capabilities such as service discovery and routing is also essential to decouple service providers and consumers.

• Question 117:

  The Service-Oriented Integration architecture makes a distinction between technical orchestrations and business processes. Which statement best describes these two concepts?

  A. A business processes is likely to change when the business changes, whereas a technical orchestration is likely to change when back-end systems change.

  B. A business process that is implemented within SOIis called a technical orchestration.

  C. Each business process is implemented by calling a sequence of SOA Services. This sequential calling of SOA Services Is what is known as a technical orchestration.

  D. A technical orchestration is a low-level implementation detail and has no relationship to business processes.

  E. Business processes are implemented using BPMN, whereas technical orchestrations are Implemented using BPEL.

  Correct Answer: A

  Explanation:

  Technical orchestration is separated from business processes. Making a clear distinction between

  technical aspects and business aspects facilitates maintenance of both. Technical aspects change when the underlying systems change whereas business aspects change when the business changes.

• Question 118:

  Data is often said to exist in one of three states:

  1.

  In motion being transmitted over a network or connection

  2.

  At rest persisted in a queue, disk, file, and so on

  3.

  In memory loaded into computer memory

  The third state, in memory, is seldom mentioned in security standards, texts and requirements. Why?

  A. Computer memory has built-in parity checking which protects against malicious alteration

  B. No one has direct access to a computer's memory, therefore it is the safest place to be.

  C. All modern computers (developed since the mid-90s) automatically store data in memory in encrypted from to help ensure confidentiality and integrity, because of this, more emphasis has been placed on raising the level of protection in the other two states.

  D. This state is often overlooked. Data in memory can easily be viewed by anyone with system administrator.

  Correct Answer: D

  Explanation:

  In Memory - a term used here to describe data that is currently being processed and therefore exposed to

  any program, diagnostic tool, operating system command, virus, etc. that is able to access memory.

• Question 119:

  Which statement best describes the relationship between the Service-Oriented Integration (SOI) architecture and the Application Integration Architecture (AIA) product from Oracle?

  A. AIA is a product specific Implementation of the SOI architecture.

  B. AIA is a traditional Enterprise Application Integration (EAI) architecture; therefore AIA does not follow the SOI architecture.

  C. AIA is an Oracle product that maps to some of the layers and capabilities defined by the SOI architecture.

  D. AIAis an Oracle product and the SOI architecture is a product-agnostic architecture; therefore there is no relationship between the two.

  E. AIA is one of many Oracle products that maps onto SOI architecture.

  Correct Answer: E

  Explanation:

  There are two categories of Oracle products that map into the service-oriented integration architecture,

  Fusion Middleware products and the Application Integration Architecture (AIA) products.
