CISA 每日一题(答)
一个合理建造的数据仓库应当支持下列三种基本的查询格式:
1、向上溯源和向下溯源——向上溯源是对数据进行总计;向下溯源是将数据进行细化;
2、交叉溯源——通过通用属性访问数据仓库中内容有交叉的信息
3、历史分析——数据仓库应当储存具有时间变量的数据,支持数据历史分析 IT 服务包括: 信息系统运行、IT 服务和信息系统管理,以及负责支持的群体

以下哪项技术描述了在单个计算机系统中使用多个处理器来增加计算机应用环境中的计算性能?
A. 流水线
B. 多任务
C. 多道程序设计
D. 多重处理
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.

针对正在考虑购置的新应用程序软件包,IS审计师评估其控制规范的最佳时间是在:
A .内部实验测试阶段。
B .测试和用户接受之前。
C .需求收集期间。
D .可行性研究阶段。
答案:C IS审计师的最佳参与时间是在应用程序软件开发或购置的需求定义开始之时。这是审查供应商及其产品的最好机会。后期参与(如在测试或接受阶段)会导致资源限制,妨碍完整评估。IS审计师的早期参与也会最大程度地减少对给定解决方案的业务承诺需求,其随着流程的继续可能会难以克服。但是,在可行性分析阶段评估控制可能还为时过早。
