• Question 91:

  Conceptually, management and monitoring capabilities consist of which of the following?

  A. consolidating administration tasks for a variety of infrastructure components
  B. homogeneous support for IT management environments
  C. skilled architects to perform root-cause analysis
  D. allowing enterprises to define, model, capture, and consolidate monitoringinformation into a single framework
  A. consolidating administration tasks for a variety of infrastructure components
  D. allowing enterprises to define, model, capture, and consolidate monitoringinformation into a single framework

• Question 92:

  Conventional Management and Monitoring tools focus and produce metrics on which one of the following?

  A. holistically across heterogeneous systems
  B. metrics that measure individual resources
  C. metrics that focus on understanding the relationship and Interactions between component
  D. metrics that capture the combined behavior of several components interacting with the shared component
  B. metrics that measure individual resources

  ---

  Conventional tools tend to focus and produce metrics on individual resources which is inadequate for an agile shared services computing environment.

  Note:

  A metric is a unit of measurement used to report the health of the system that is captured from the monitored infrastructure components. Metrics from all monitored infrastructure components are stored and aggregated in the Management

  Repository, providing administrators with a rich source of diagnostic information and trend analysis data.

• Question 93:

  When two or more technology perspectives are combined, which statement best describes how the Oracle Reference Architecture (ORA) applies to the combination?

  A. One of the layersin ORAis the Business Services layer that contains the SOA Services. It is these SOA Services that provide the connection between different technology perspectives; therefore the Business Services layer is the interlock between two or more technology perspectives.
  B. Each technology perspective adds to the core ORA capabilities. The core ORA capabilities support each of the technology perspectives by providing a common foundation.
  C. The vertical layersin ORA (Enterprise Development, Enterprise Security. Enterprise Management) provide the capabilities needed to combine two or more technology perspectives.
  D. Each technology perspective is a separate reference architecture that leverages ORA as the common foundation for each of the individual reference architectures.
  E. The vertical layers of ORA are identical for each technology perspective. Each technology perspective adds capabilities to the horizontal layers of ORA, especially the business Processes, Business Services, and Information Assets layers.
  A. One of the layersin ORAis the Business Services layer that contains the SOA Services. It is these SOA Services that provide the connection between different technology perspectives; therefore the Business Services layer is the interlock between two or more technology perspectives.

  ---

  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.

  Documenting how each technology perspective relates and combines with all the other technology perspectives would be onerous and unwieldy. This is the reason that ORA embraces service orientation at the core so that services provide a

  consistent mechanism to expose and combine various technologies and the capabilities.

  D. Oracle WebCenter Spaces
  C. Oracle WebCenter Real-Time Collaboration

  ---

  Oracle WebCenter Real-Time Collaboration improves efficiency and productivity by enabling users to connect and collaborate with others via instant messaging, presence, chat rooms, and web and voice conferencing. It complements other Enterprise 2.0 services available in Oracle WebCenter by offering real- time collaboration capabilities to users who require direct interaction and immediate response.

• Question 95:

  Which statements arc true about Rich Internet Applications (RIAs)?

  A. A Rich Internet Application (RIA) is a web application that provides the type of sophisticated user Interface that has traditionally requiredadedicated desktop client.
  B. There are a variety of technologies being applied to create RIAs, but all provide a sophisticated user interface delivered through a browser.
  C. Rich Internet Applications provide only limited functionality and the traditional fat client is still needed in cases such as those requiring animation.
  D. Rich Internet Applications transfer all the business application processing to the client, thereby reducing the cost of the server infrastructure.
  A. A Rich Internet Application (RIA) is a web application that provides the type of sophisticated user Interface that has traditionally requiredadedicated desktop client.
  B. There are a variety of technologies being applied to create RIAs, but all provide a sophisticated user interface delivered through a browser.

  ---

  A Rich Internet Application (RIA) is a Web application that has many of the characteristics of desktop application software, typically delivered by way of a site-specific browser, a browser plug-in, an independent sandbox, extensive use of JavaScript, or a virtual machine. Adobe Flash, JavaFX, and Microsoft Silverlight are currently the three most common platforms.

  Not D: Rich internet applications (RIA) move some (but usually not all) of the view and controller functionality to the Client Tier.

  Note: Web 2.0 introduces even more client-side code to enrich the user experience (i.e. Rich Internet Applications). This can be done in a standardized way, such as the Ajax framework. New message- injection attacks are possible in areas such as cross-site scripting and cross-site-forgery due to poor protocol implementations and poor message parsing. An example exploit is the SAMY worm created on MySpace.

• Question 96:

  Which statement best describes the relationship between a Service Contract and a Usage Agreement as defined by the Oracle Reference Architecture (ORA)?

  A. There is a one-to-one relationship between a Service Contract and a Usage Agreement. For each Service Contract there is a corresponding Usage Agreement.
  B. There may be multiple Usage Agreements associated with a single Service Contract.
  C. There may be multiple Service Contracts associated with a single Usage Agreement.
  D. There is a many-to-many relationship between Service Contracts and Usage Agreements.
  E. There is no defined relationship between a Service Contract and a Usage Agreement.
  B. There may be multiple Usage Agreements associated with a single Service Contract.

  ---

  The Service Contract defines what the SOA Service agrees to provide to the environment.

  The service consumer Usage Agreement defines what a particular service consumer is entitled to consume.

  Each service might have several consumers.

  The Service provider must ensure that the Service will satisfy the aggregate specifications of all related usage agreements.

  Note:

  The usage agreement is not part of the Service; rather it defines what a particular service consumer is entitled to consume from the Service.

  Having both a usage agreement and a service contract provides a decoupling between the service provider and service consumer. This not only facilitates reuse but also provides a separation of concerns. The service contract defines the

  totality of what the Service guarantees to provide, and can be written and validated independent of any knowledge of specific service consumers. The usage agreement is service consumer specific and defines what capabilities of the Service

  each consumer is allowed to consume.

• Question 97:

  There are various network topologies that can be used when deploying the Service-Oriented Integration architecture. One deployment option includes three networks: production network, services network and maintenance network. Which statement best describes the uses of these three networks?

  A. The production networkisused for all production network traffic. The services networks is used to deploy and configure SOA Services. The maintenance network is used by the operations team to manage the infrastructure.
  B. The production network provides connectivity to applications and client access to the Mediation Layer. The services network provides connectivity between the Mediation Layer and the SOA Services. The maintenance network is used by the operations team to manage the infrastructure.
  C. The production network provides connectivity to applications and client access to the Mediation Layer- The services networks is used to deploy and configure SOA Services. The maintenance network is used by the operations team to manage the infrastructure.
  D. The production network is used for all production network traffic. The services network provides connectivity between the Mediation Layer and the SOA Services. The maintenance network is by the operations team to manage the infrastructure.
  E. The production network is used for all production network traffic. The services networks is used to deploy and configure SOA Services. The maintenance network is trusted network, providing administrator access to all hardware and software.
  B. The production network provides connectivity to applications and client access to the Mediation Layer. The services network provides connectivity between the Mediation Layer and the SOA Services. The maintenance network is used by the operations team to manage the infrastructure.

  ---

  Note: Mediation can be broadly defined as resolving the differences between two or more systems in order to integrate them seamlessly. A typical IT architecture has a variety of systems and components that are fundamentally different. A better alternative to embedding the mediation logic into each of these systems would be to provide the mediation capability in the SOA infrastructure.

• Question 98:

  What is the main benefit of Utility Computing?

  A. high availability
  B. better economics
  C. scalability
  D. better security
  B. better economics

  ---

  The focus of utility computing is the business model on which providing the computing services are based. The main benefit of utility computing is better economics. Corporate data centers are typically underutilized. Utility computing allows companies to only pay for the computing resources they need, when they need them. Utility computing is very similar to public cloud computing, except perhaps it doesn't necessarily imply self-service, elastic capacity, or multi-tenancy. It does imply pay-per-use.

  Note: Utility computing is an on-demand approach that combines outsourced computing resources and infrastructure management with a usage-based payment structure. It covers the packaging of computing resources, such as computation and storage, as a metered service similar to a physical public utility. Utility computing has the advantage of a low or no initial cost to acquire hardware as computational resources are essentially rented.

• Question 99:

  Which statements are true with regard to authorization checks being done in the Mediation Layer?

  A. Performing authorization checksin the Mediation Layer provides a centralized approach to securing SOA Services.
  B. Performing authorization checks in the Mediation Layer requires that all secured SOA Services be accessed via the same protocol.
  C. Performing authorization checks in the Mediation Layer requires that all secured SOA Services be accessed only via the Mediation Layer.
  D. Performing authorization checks in the Mediation Layer eliminates the need for role-based authentication.
  E. Performing authorization checks in the Mediation Layer requires that user authentication be based on username and password.
  A. Performing authorization checksin the Mediation Layer provides a centralized approach to securing SOA Services.
  D. Performing authorization checks in the Mediation Layer eliminates the need for role-based authentication.

  ---

  Mediation is a key component in the overall architecture providing the decoupling between consumers and providers.

  A: Although not always required, leveraging the authorization capability within the Mediation Layer provides a centralized approach to securing SOA Services.

  Note:

  In addition to run time Service endpoint discovery, SOA infrastructure can provide additional value by acting as an intermediary and mediator between consumers and providers. For example, intermediaries can bridge the technology gaps

  between the two parties. Among their many capabilities are:

  *

  Translate (map) security credentials between different users/groups/roles or between different credential types

  *

  Translate, or transform request and response messages

  *

  Accept requests via one transport or protocol and forward them on using a different transport or protocol (not B)

  *

  Route messages based on content within the request message (Content-based routing)

  *

  Route messages based on security policies

  *

  Add or remove security measures such as encryption and certificates

  *

  Invoke multiple Service providers as part of a single Service request

  *

  Audit and/or log requests

  *

  Deny requests based on access policies (SLAs, Usage Agreements)

  *

  Capture response time metrics and usage metrics

  *

  Monitor and report on error conditions

• Question 100:

  What does the Identity Asserter do in a J2EE framework?

  A. It informs the container of the client identity of an inbound request.
  B. It Inserts identity into Web Service credentials used for outbound service requests.
  C. It determines a user's identity based on a given set of security roles and asserts it to the container.
  D. It resolves Identity conflicts when multiple LDAPs are used.
  B. It Inserts identity into Web Service credentials used for outbound service requests.

  ---

  Like the Authenticator, theIdentity Assertersecurity provider uses Oracle Access Manager authentication services to validate already-authenticated Oracle Access Manager users using the ObSSOCookie and to create a WebLogicauthenticated session.

  Note: If authentication is successful, the identity asserter creates a Subject, which is used to identify the user. Actions performed by the user will be associated with the Subject so that the caller's identity will be known. If outbound requests are made by the business logic, identity can be included by the container based on the Subject.
