質問 1：
The Oracle Reference Architecture (ORA) includes the concept of Technology Perspectives. Which statements are true concerning ORA and Technology Perspectives?
A. A Technology Perspectiveincludesboth reference architecture views as well as practical guidance and approaches for successfully implementing the changes required to embrace the products and technology.
B. Each Technology Perspective is part of ORA and is part of an Enterprise Technology Strategy;
i.e. a Technology Perspective is the connection between ORA and an Enterprise Technology.
C. The Technology Perspectives can be used individually or in combinations, for example, SOA with BI.
D. Each Technology Perspective focuses on a particular set of products and technology.
E. The Technology Perspectives can be used individually or in combinations. When used in combinations, the SOA Technology Perspective must be included.

質問 3：
Conceptually, the ORA model of a "modern UI" defines which three layers from the following list?
A. Browser Mediation layer adapts output to conform to the standards and capabilities of each browser type.
B. Unified User Interface layer provides the control and visual elements that define the interaction that the user has with the system.
C. Device Management layer provides transformation and transcoding to support a wide variety of devices.
D. Access and Incorporation layer provides the capability to Incorporate data and functionality from any number of back-end systems into the user interface.
E. User Interface Services layer provides reusable functions specialized to the needs of the end
F. Integration layer provides connectors to simplify and standardize Interaction with back-end terns.

質問 4：
Interface elements are an important part of modular programming for UI. Which of the following statements is true with regard to Interface elements?
A. Interface elements implement application-specific functionality and are therefore rarely reusable across multiple applications.
B. Interface elements are always provided as proprietary packages of widgets from device vendors and third parties.
C. There is a wide variety of interface elements that can be developed once and used repeatedly in various user-interface designs.
D. Interface elements are highly standardized and, once developed for one device, they are sufficiently portable to be reused on other devices without modification.

質問 5：
What are the two primary approaches of visualization?
A. Server Management - managing the servers by using a single-point management interface
B. Server Sprawl - leads to a disproportionate amount of physical server machines running at very low rates of usage
C. Server Visualization - creating multiple logical virtual machines on top of a single hardware platform
D. Server Consolidation - abstracting the complexities of the underlying pool of servers by creating aggregated logical machines
正解：A,D

質問 7：
The Conceptual, Logical, and Product Mapping architecture views are core to the documents within the Oracle Reference Architecture (ORA) library- Which statement best describes the relationship between these three architectural views?
A. The Conceptual view lists the concepts behind the architecture, the Logical view describes the rationale for the architecture, and the Product Mapping view Identifies the Oracle products required.
B. Each architecture view is designed to communicate to a specific stakeholder and there is no defined relationship between the views.
C. The Conceptual view defines the architecture in less technical terms, the Logical view provides Increasing detail by using more technical terms, and the Product Mapping view maps Oracle products onto the Logical view.
D. Each architecture view is a description of the components within the architecture, the logical view describes the runtime interactions between the components, and the product mapping view illustrates the deployment of Oracle products.
E. The Conceptual view is a high-level description of the architecture, the Logical view is a detailed description of the architecture, and the Product Mapping view illustrates the deployment of Oracle products.
正解：E

質問 8：
Select the most appropriate reason why three-tier architecture is a better architectural choice than simple client-server architecture for complex enterprise applications.
A. Three-tier architecture moves all processing to the client, thereby reducing the load on the server.
B. Three-tier architecture combines presentation, business logic, and data processing into a single layer to eliminate network latencies.
C. Three-tier architecture uses three threads to run the applications, so performance is better.
D. Three-tier architecture combines presentation, business logic, and data processing of business logic, data, and presentation. This allows the tiers to be independently scaled to maximize the investment.
