CISA 每日一題(答)
一個合理建造的數據倉庫應當支持下列三種基本的查詢格式:
1、向上溯源和向下溯源——向上溯源是對數據進行總計;向下溯源是將數據進行細化;
2、交叉溯源——通過通用屬性訪問數據倉庫中內容有交叉的信息
3、歷史分析——數據倉庫應當儲存具有時間變量的數據,支持數據歷史分析 IT 服務包括: 信息系統運行、IT 服務和信息系統管理,以及負責支持的群體

以下哪項技術描述了在單個計算機系統中使用多個處理器來增加計算機應用環境中的計算性能?
A. 流水線
B. 多任務
C. 多道程序設計
D. 多重處理
Answer: D Multiprocessingis an organizational technique in which a number of processor units areemployed in a single computer system to increase the performance of the systemin its application environment above the performance of a single processor ofthe same kind. In order to cooperate on a single application or class ofapplications, the processors share a common resource. Usually this resource isprimary memory, and the multiprocessor is called a primary memorymultiprocessor. A system in which each processor has a private (local) mainmemory and shares secondary (global) memory with the others is a secondarymemory multiprocessor, sometimes called a multicomputer system because of thelooser coupling between processors. The more common multiprocessor systemsincorporate only processors of the same type and performance and thus arecalled homogeneous multiprocessors; however, heterogeneous multiprocessors arealso employed. A special case is the attached processor, in which a secondprocessor module is attached to a first processor in a closely coupled fashionso that the first can perform input/output and operating system functions,enabling the attached processor to concentrate on the application workload.

針對正在考慮購置的新應用程序軟件包,IS審計師評估其控制規範的最佳時間是在:
A .內部實驗測試階段。
B .測試和用戶接受之前。
C .需求收集期間。
D .可行性研究階段。
答案:C IS審計師的最佳參與時間是在應用程序軟件開發或購置的需求定義開始之時。這是審查供應商及其產品的最好機會。後期參與(如在測試或接受階段)會導致資源限制,妨礙完整評估。IS審計師的早期參與也會最大程度地減少對給定解決方案的業務承諾需求,其隨著流程的繼續可能會難以克服。但是,在可行性分析階段評估控制可能還為時過早。
