Question No: 11
Conceptually, the ORA model of a quot;modern UIquot; defines which three layers from the following list?
Unified User Interface layer provides the control and visual elements that define the interaction that the user has with the system.
Integration layer provides connectors to simplify and standardize Interaction with back- end -terns.
Device Management layer provides transformation and transcoding to support a wide variety of devices.
Browser Mediation layer adapts output to conform to the standards and capabilities of each browser type.
User Interface Services layer provides reusable functions specialized to the needs of the end
Access and Incorporation layer provides the capability to Incorporate data and functionality from any number of back-end systems into the user interface.
Answer: A,E,F 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
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 No: 12
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?
Composite application assembly and SOA Service engineering are separate, decoupled efforts without any meaningful Interaction.
All SOA Service engineering must be completed prior to any composite application assembly.
Composite application assembly uses service contracts created by SOA Service engineering and generates requirements that are Inputs to SOA Service engineering.
SOA Service engineering creates SOA Services following sound engineering principles, while composite application assembly uses SOA Services based on WSPL interfaces.
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 amp; 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.
Service OAamp;M –
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 No: 13
What are the benefits of the browser over traditional user Interfaces (for example, client- server GUI)?
HTML provides a richer interface for end users.
Development, maintenance, and support costs are reduced.
The browser simplifies application deployment compared to dedicated client server GUI applications.
There is more variety among browsers than among client-server GUIs.
The browser provides a richer graphical environment than client-server GUIs.
Browsers can support more diverse devices than dedicated client-server GUI application.
Question No: 14
Which of the following is not an objective or function of the WS-Trust standard?
to enable applications to construct trusted SOAP message exchanges
to synchronize Identities across security domains
to exchange tokens in order to overcome differencesin supported technology between service consumers and service providers
to exchange tokensin order to mapidentities supplied by service consumers with identities supported by service providers
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 No: 15
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?
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.
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.
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.
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.
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.
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 No: 18
Interface elements are an important part of modular programming for UI. Which of the following statements is true with regard to Interface elements?
Interface elements are always provided as proprietary packages of widgets from device vendors and third parties.
There is a wide variety of interface elements that can be developed once and used repeatedly in various user-interface designs.
Interface elements are highly standardized and, once developed for one device, they are sufficiently portable to be reused on other devices without modification.
Interface elements implement application-specific functionality and are therefore rarely reusable across multiple applications.
Explanation: Interface element that a computer user interacts with, and is also known as a control or Widget.
Examples: Windows, Pointer, Text Box, Button, Hyperlink, Drop-down list, List box, Combo box, Check Box, Radio button, Cycle button, Datagrid
