亚马逊云AWS认证助理工程师题库第三题

题目

You are working for a University as their AWS Consultant. They want to have a disaster recovery strategy in AWS for mission-critical applications after suffering a disastrous outage wherein they lost student and employee records. They don’t want this to happen again but at the same time want to minimize the monthly costs. You are instructed to set up a minimum version of the application that is always available in case of any outages.
Which of the following disaster recovery architectures is the most suitable one to use in this scenario?

A. Backup & Restore
B. Pilot Light
C. Warm Standby
D. Multi Site

注释

正确答案是:Pilot Light。
Pilot light 通常用于描述在云上运行的环境中最小版本的DR方案。“Pilot Light”的概念是来自煤气炉的专用名词。在煤气炉中,总是能在打着火后迅速点燃整个熔炉,使得屋内快速升温。此方案可以类比为备份和还原方案。

答案

B
