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.

Which of the following environments are typically clustered?
A. Development Environment
B. User Acceptance Testing (UAT) Environment
C. Staging Environment
D. Nonfunctional Testing Environment
Correct Answer: B
Explanation:
UAT (also known as beta testing) : Formal testing with respect to user needs, requirements, and business
processes conducted to determine whether or not a system satisfies the acceptance criteria and to enable
the user, customers or other authorized entity to determine whether or not to accept the system.
Incorrect answer:
The staging tier is a environment that is as identical to the production environment as possible. The
purpose of the Staging environment is to simulate as much of the Production environment as possible. The
Staging environment can also double as a Demonstration/Training environment.

In order to support rapid development, which one of the following principles must be applied?
A. The architecture must provide a Rapid Application Development framework for user interface development.
B. The architecture must provide guided development of the user interface without needlessly exposing the developer to implementation details.
C. The architecture must provide access to the full implementation details of the interface in order permit maximum flexibility in the development process.
D. Usability best practices are incorporated into proven user-interface techniques.
Correct Answer: B
Explanation:
The architecture must provide rapid, guided development of the user interface without needlessly exposing
the developer to implementation details.
Reducing the time and resources required to deliver business solutions is required for IT to better support
and align with business needs. Low level development is both time consuming and error prone.
