• Question 161:

  Which four components of the following list should be found in the client tier of the Logical view of the Oracle Reference Architecture User Interaction?

  A. Personalization

  B. Communication services

  C. State management

  D. Customization

  E. Collaboration

  F. Syndication

  G. Controller

  H. Rendering

  Correct Answer: BCGH

  Explanation:

  The Client Tier is hosted on the display device. As mentioned above, this may be a browser or an thick

  client specific to the display device.

  Regardless of the choice for the Client Tier, there are standard capabilities provided by this tier in the

  architecture:

  Controller: The Controller accepts input from the user and performs actions based on that input. State

  Management: The State Management component is responsible for maintaining the current state of the

  user interface.

  Rendering: The Rendering component is responsible for delivering a view of the interface suitable for the

  end user.

  Communication Services: The Communication Services provide the means to access Service Tier

  capabilities.

  Note: Security Container, Data Management and Composition can also be included here.

• Question 162:

  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.

  Correct Answer: B

  Explanation: 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 163:

  Which of the following is not an objective or function of the WS-Trust standard?

  A. to enable applications to construct trusted SOAP message exchanges

  B. to synchronize Identities across security domains

  C. to exchange tokens in order to overcome differencesin supported technology between service consumers and service providers

  D. to exchange tokensin order to mapidentities supplied by service consumers with identities supported by service providers

  Correct Answer: A

  Explanation: Oracle STS leverages the WS-Trust standard protocol to manage token exchange between the Web Service Client (WSC) and the Web Service Provider (WSP) (not C). WS-Trust provides a standard way to send security token requests to any Security Token Service (STS) (not D). This specification can be used to manage token transformation when crossing the various security boundaries of the information system (not B).

• Question 165:

  A longer term goal of Service-Oriented Integration (SOI) is to enable composite applications that are assembled from SOA Services. Which statement best describes the relationship between composite application assembly and SOA Service engineering?

  A. Composite application assembly and SOA Service engineering are separate, decoupled efforts without any meaningful Interaction.

  B. All SOA Service engineering must be completed prior to any composite application assembly.

  C. Composite application assembly uses service contracts created by SOA Service engineering and generates requirements that are Inputs to SOA Service engineering.

  D. SOA Service engineering creates SOA Services following sound engineering principles, while composite application assembly uses SOA Services based on WSPL interfaces.

  Correct Answer: C

  Explanation:

  

  The Oracle Service Engineering Framework is an engineering approach for delivering projects within an SOA environment The Service Engineering Framework addresses activities at both the program and project scope to consider the requirements of the business outside of the scope of a single project. Topics covered at the program scope include:

  *

  SOA Requirements Management - Provides a process for harvesting requirements in a manner that naturally facilitates service identification and discovery.

  *

  Service Identification and Discovery - Establishes the procedures around identifying Service candidates, as well as discovering reuse candidates from the existing Service catalog. Takes the process from identification and discovery, through the justification processes required to determine if an existing Service can be viable for reuse in the proposed manner, or if the proposed Service Candidate should be realized as a shared Service.

  *

  Service Release Planning - Provides the groundwork necessary for planning for project and Service deliveries within an SOA

  Topics covered at the project scope include:

  *

  Service Definition

  *

  Service Design

  *

  Service Implementation - Provides the guidelines for effectively and efficiently developing shared Services.

  *

  Service Testing

  *

  Service Deployment - Defines the guidelines and practices that need to be considered when deploying Services into a shared environment.

  *

  Note: The primary goal of service-oriented integration is to better leverage existing systemwithin the IT environment by applying service-oriented principles. Ultimately, the goal is to enable the assembly of composite applications, with little or no custom coding, that include capabilities sourced from existing systems. Composite applications are applications that pull together data, functionality, and process from multiple existing sources to solve a business problem or create new business value. Service-oriented integration is the mechanism to expose existing sources of data, functionality, and process so that those sources can be readily consumed by a composite application

• Question 166:

  Conceptually, the ORA model of a "modern UI" defines which three layers from the following list?

  A. Unified User Interface layer provides the control and visual elements that define the interaction that the user has with the system.

  B. Integration layer provides connectors to simplify and standardize Interaction with back-end -terns.

  C. Device Management layer provides transformation and transcoding to support a wide variety of devices.

  D. Browser Mediation layer adapts output to conform to the standards and capabilities of each browser type.

  E. User Interface Services layer provides reusable functions specialized to the needs of the end

  F. Access and Incorporation layer provides the capability to Incorporate data and functionality from any number of back-end systems into the user interface.

  Correct Answer: AEF

  Explanation: Note:

  

  A: The Unified User Interface layer provides the control and visual elements that define the interaction the user has with the system. This layer separates the way the user interacts with the system from the underlying functionality provided by the system. This has many advantages including allowing different display devices to be supported via control and visual elements specialized for the device since, for example, mobile devices do not have nearly the screen real estate of a desktop computer.

  E: The User Interface Services layer provides a set of functionality that can be used and reused in a variety of ways to deliver various user interfaces specialized to the needs of the end user. This illustrates that the underlying functionality is separated from the visual and control elements built into the user interface. The services provided by this layer may come from a variety of sources located anywhere that is network accessible.

  F: The Access and Incorporation layer provides the capability to incorporate data and functionality from any number of backend systems into the user interface. Generally, there are two types of backend systems that need be incorporated into the user interface: systems that are designed for use with user interface

  (e.g. LDAP, dedicated database) and systems that are not (e.g. legacy applications). The former type systems can be access directly by the user interface architecture. Ideally the latter type should be accessed via a robust integration architecture rather than relying on point-to-point integrations. This distinction is the reason that the term "incorporation" is used in this Conceptual View instead of the term "integration." A suitable integration architecture is described in the ORA Service-Oriented Integration document.

• Question 167:

  Which of the following statements are true about an end-to-end security strategy?

  A. End-to-end security and point-to-point security are virtually identical strategies proposed by different security vendors.

  B. End-to-end security strives to protect data at rest, even in temporary queues.

  C. End-to-end security often involves some form of message-level protection.

  D. When end-to-end security is enabled. Point-to-point transport-level encryption should be disabledin order to avoid cryptography conflicts between layers.

  E. End to-end security is highly beneficial for distributed computing environments where many point- point connections and intermediaries exist, because it offers seamless data protection.

  Correct Answer: BCE

  Explanation:

  B:End to end security is an information-centric perspective of security where information is protected

  throughout the entire computing environment. That is, from the points where system interactions originate,

  through all points of integration, processing, and persistence.

  End to end security is often associated with the secure transmission, processing, and storage of data,

  where at no time are data unprotected Note:

  For a typical web-based application, end to end security generally begins at the client/browser, and ends at

  the application database and all external dependencies of the application.

  A common challenge in providing end to end security is finding a suitable way to secure data in all states

  and points along the processing path that does not interfere with any transmission, routing, processing,

  and storage functions that need to occur along the way. Sensitive data will usually need to be decrypted at

  certain points in order for processing or message routing to occur.

• Question 168:

  Which of the following are the key drivers for Grid computing?

  A. Improved server utilization - Grid computing allows companies to lower costs through the efficient use of resources.

  B. Better agility and flexibility - Businesses experience constant change and the underlying IT Infrastructure should be agile enough to support that kind of change.

  C. OpEx model - Enterprises require pay-as-you-go services to reduce the dependency on capital expenditure and take advantage of the benefits of operational expenditure.

  D. Lower Initial cost-There is a need to reduce the Initial investment at the cost of an increased operational cost.

  Correct Answer: ABD

  Explanation: Using a grid computing architecture, organizations can quickly and easily create a large-scale computing infrastructure from inexpensive, off-the-shelf components (D). Other benefits of grid computing include

  *

  Quick response to volatile business needs (B)

  *

  Real-time responsiveness to dynamic workloads

  *

  Predictable IT service levels

  *

  Reduced costs as a result of improved efficiency and smarter capacity planning (A) Note: One way to think about grid computing is as the virtualization and pooling of IT resources-- compute power, storage, network capacity, and so on--into a single set of shared services thatcan be provisioned or distributed, andthen redistributed as needed. As workloads fluctuate during the course of a month, week, or even through a single day, the grid computing infrastructure analyzes the demand for resources in real time and adjusts the supply accordingly.

  Grid computing operates on three basic technology principles: Standardize hardware and software components to reduce incompatibility and simplify configuration and deployment; virtualize IT resources by pooling hardware and software into shared resources; and automate systems management, including resource provisioning and monitoring.

  Grid computing operates on these technology principles:

  *

  Standardization.

  *

  Virtualization.

  *

  Automation.

• Question 169:

  Bottom-up service Identification analyzes existing systems to Identify SOA Services. Top-down service identification analyzes business processes to identify SOA services.

  Which statement best describes the relationship between top down and bottom-up service identification in Service-Oriented Integration?

  A. Only a bottom up approach shouldbe used because the goal of SOIis to provide SOA Services exposing existing systems.

  B. Only a top-down approach should be used because the goal of SOI is composite application assembly.

  C. A bottom-up approach should be used to identify which SOA Services are built; then a top-down approach should be used to determine which SOA Services are used by each composite application.

  D. A top-down approach should be used to determine the needed SOA Services; then a bottom-up approach should be used to determine how existing source systems can meet the requirements top-down approach should be used by business, and a bottom-up approach should be used by IT.Theoverlap between the SOA Services Identified by the two methods are the ones that should

  Correct Answer: D

  Explanation:

  Note: There are three schools of thought around "how to build an Enterprise Service Oriented Architecture." They are:

  *

  Top down - central group decides everything and the dev teams adopt them.

  *

  Bottom up - central group provides a directory and dev teams make whatever services they want. Dev teams go to the directory to find services they can use.

  *

  Middle out - central group provides key elements of the interface, including numbering schemes, message exchange patterns, standard communication mechanisms, and monitoring infrastructure, and encourages the dev teams to use it to build services that can be shared.
