Which of the following phases deals with identifying and p

43、rioritizing critical functions and systems?（分数：2.00）A.Identify preventive controls.B.Develop the continuity planning policy statement.C.Develop recovery strategies.D.Conduct the business impact analysis. 解析：解析：D 正确。尽管创建连续性计划没有具体的科学方程式可以遵循，但某些最佳做法已经经过了时间的考验，证明了自己的价值。美国国家标准技术研究院(National Institute of

44、Standards and Technology，NIST)是一家负责开发最佳做法并记录它们从而方便所有人使用的组织。NIST 在它的专门出版物 800-34，Continuity Planning Guide for Information Technology Systems 中概述了 7 个步骤：制定连续性计划说明书、进行业务影响分析、确定预防控制措施、制定恢复战略、制定应急计划、测试应急计划、进行训练和演习，以及维护计划。进行业务影响分析包括确定关键功能和系统，使组织根据需要对它们进行优先级排列。此外，它还包括确定漏洞和威胁，以及计算风险。 A 不正确。因为确定预防控制措施必须在对关键

45、功能和系统的优先级进行了排列、确定了它们的漏洞、威胁和风险(它是业务影响分析的一部分)之后进行。进行业务影响分析是创建连续性计划的第 2 步，制定预防控制措施是第 3 步。 B不正确。因为制定连续性计划政策说明书主要涉及撰写指南，该指南是制定业务连续性计划提供的必备，也用于给必要的角色授权以执行这些任务。它是创建连续性计划的第 1 步，因而排在确定和对关键系统和功能进行优先级排序(即进行业务影响分析)步骤之前。 C 不正确。因为制定恢复战略涉及制定确保系统和关键功能能够快速上线的方法。在此之前，必须进行业务影响分析，判断哪个系统和功能是关键的，所以应该在恢复时优先考虑。2.As his com

46、panys business continuity coordinator, Matthew is responsible for helping recruit members to the business continuity planning (BCP) committee. Which of the following does not correctly describe this effort?（分数：2.00）A.Committee members should be involved with the planning stages, as well as the testi

47、ng and implementation stages.B.The smaller the team the better, to keep meetings under control. C.The business continuity coordinator should work with management to appoint committee members.D.The team should consist of people from different departments across the company.解析：解析：B 正确。为了能表示组织内的每一个部门，业

48、务连续性计划(Business ContinuityPlanning，BCP)委员会的规模应该足够大。其成员必须由熟悉公司的不同部门的人组成，因为每个部门都有自己独特的功能，也面临各自不同的风险和威胁。最好的业务连续性计划是将所有问题和威胁都拿到桌面上来讨论。只由少量熟知一两个部门的人进行讨论的效果肯定不好。这个委员会至少应该由来自下列部门的代表组成：业务部门、高层管理、IT 部门、安全部门、通信部门和法律部门。 A 不正确。因为委员会成员应该参与到计划、测试、实施等各阶段的工作中。假如 BCP 协调人 Matthew 是一个优秀管理者，那么他应该懂得最好让团队成员对他们的任务和角色有一种主人

49、翁的责任感。制定业务连续性计划的人也应该是执行业务连续性计划的人。如果你知道在危急时刻需要执行一些关键任务，那么你在计划和测试阶段或许会更加注意这一点。 C 不正确。因为 BCP 协调人应该与管理层一起任命委员会成员，但管理层的参与却不仅限于此。BCP 团队应该与管理层一起制定这个计划的终极目标，确认在灾难发生时首先应该处理的关键业务内容，以及弄清部门和任务的优先级。管理层也需要帮助委员会团队确定项目的范围和特定目标。 D 不正确。因为委员会团队应该由来自公司不同部门的人构成。这是团队能够考虑到每个部门所面对的不同风险和威胁的唯一办法。3.A business impact analysis is considered a functional analysis. Which of the following is not carried out during a business impact analysis?（分数：2.00）A.A parallel or full-interruption test B.The application of a classification scheme based on criticality levelsC.The gathering of information via interviewsD.Documenta
