質問 2：
You are going to create live zones on you server. Disk space is critical on this server so you need to reduce the amount of disk space required for these zones.

Which two options provide a solution for eliminating the duplicate copies of data that is common between all of these zones?
A. Put each zone in a separate ZFS file system within the same zpool. Set the dedup property to on for each ZFS file system.
B. Set the dedup property to on and the dedupratio to at least 1.5 for the zpool. Create a separate ZFS file system for each zone in the zpool.
C. Put all of the zones in the same ZFS file system and set the dedup property for the file system to on.
D. Create the zones by using sparse root zones.
