CISA 每日一題（答）

一個(gè)合理建造的數(shù)據(jù)倉(cāng)庫(kù)應(yīng)當(dāng)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(duì)數(shù)據(jù)進(jìn)行總計(jì)；向下溯源是將數(shù)據(jù)進(jìn)行細(xì)化；

2、交叉溯源——通過通用屬性訪問數(shù)據(jù)倉(cāng)庫(kù)中內(nèi)容有交叉的信息

3、歷史分析——數(shù)據(jù)倉(cāng)庫(kù)應(yīng)當(dāng)儲(chǔ)存具有時(shí)間變量的數(shù)據(jù)，支持?jǐn)?shù)據(jù)歷史分析 ? IT 服務(wù)包括： 信息系統(tǒng)運(yùn)行、IT 服務(wù)和信息系統(tǒng)管理，以及負(fù)責(zé)支持的群體

CISSP每日一題

以下哪項(xiàng)技術(shù)描述了在單個(gè)計(jì)算機(jī)系統(tǒng)中使用多個(gè)處理器來(lái)增加計(jì)算機(jī)應(yīng)用環(huán)境中的計(jì)算性能？

A. 流水線

B. 多任務(wù)

C. 多道程序設(shè)計(jì)

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.

CISA每日一題

針對(duì)正在考慮購(gòu)置的新應(yīng)用程序軟件包，IS審計(jì)師評(píng)估其控制規(guī)范的最佳時(shí)間是在：

A .內(nèi)部實(shí)驗(yàn)測(cè)試階段。

B .測(cè)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(jì)師的最佳參與時(shí)間是在應(yīng)用程序軟件開發(fā)或購(gòu)置的需求定義開始之時(shí)。這是審查供應(yīng)商及其產(chǎn)品的最好機(jī)會(huì)。后期參與（如在測(cè)試或接受階段）會(huì)導(dǎo)致資源限制，妨礙完整評(píng)估。IS審計(jì)師的早期參與也會(huì)最大程度地減少對(duì)給定解決方案的業(yè)務(wù)承諾需求，其隨著流程的繼續(xù)可能會(huì)難以克服。但是，在可行性分析階段評(píng)估控制可能還為時(shí)過早。
