The following scenario will be used to answer questions 30, 31 and 32.
Jeff is leading the business continuity group in his company. They have completed a business impact analysis and have determined that if the company’s credit card processing functionality was unavailable for 48 hours the company would most likely experience such a large financial hit that it would have to go out of business. The team has calculated that this functionality needs to be up and running within 28 hours after experiencing a disaster for the company to stay in business. The team has also determined that the restoration steps must be able to restore data that are one hour old or less.
In this scenario, which of the following is the Recovery Time Objective (RTO) value?
选项
A、48 hours
B、28 hours
C、20 hours
D、1 hour
答案
B
解析
B正确。恢复点时间(Recovery Time Objective,RTO)指的是在一场灾难之后,为了避免无法接受的与业务持续性破坏相关的后果,业务流程必须进行恢复的最早时间段和服务级别。RTO的值比最长可承受的停机时间(MaximumTolerable Downtime,MTD)的值要小,因为MTD值表示的是如果公司在这个时间之后仍无法恢复重要的经营活动,将对公司的名声或底线带米重大、甚至是无法挽回的伤害。在这个场景中,28小时是RTO,而48小时是MTD。
A不正确。因为RTO是28小时。RTO假定存在一个可接受的停机时间。这意味着公司可以在一段时间内(RTO)停业,但仍然可以恢复到原来的状态。但是如果公司在MTD窗口内无法重启生产和运行,那么公司会因为失败得太快而无法被正常恢复。
C不正确。因为这个值即不是RTO值,也不是MTD值。
D不正确。因为这个值即不是RTO值,也不是MTD值。
