最近准备考310-202，有2道题目觉得TK的答案好像不对，大家帮忙分析下，谢谢

一。Given four volume configurations:
1. a volume created using space from a single region of one disk, which could later be grown if file system space becomes limited
2. a volume created by concatenating space from two disks using roughly equal regions from each
3. a volume created by striping the data across three equal disk regions
4. a volume created by writing the data to two disk regions, the same data to each Place the volume configurations in the order of their susceptibility to data losscaused by disk failure.

High->low
TK的答案是 3214

4. a volume created by concatenating space from two disks using roughly equal regions from each Multiple concurrent reads and writes to different disks are supported by the system.

Place the four volume configurations in the order of the speed with which they are able to write data to the disks
