Actual exam question for Oracle's 1Z0-821 exam

Question #: 13
Topic #: 8

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. Much of the data required for each of these zones is identical, so you want to eliminate the duplicate copies of data and store only data that is unique to each zone.

Which two options provide a solution for eliminating the duplicate copies of data that is common between all of these zones?

ACreate the zones by using sparse root zones.

BSet 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.

CPut all of the zones in the same ZFS file system and set the dedupratio property for the ZFS file system to at least 1.5.

DPut all of the zones in the same ZFS file system and set the dedup property for the file system to on.

EPut each zone in a separate ZFS file system within the same zpool. Set the dedup property to on for each ZFS file system.

Show Suggested Answer

Suggested Answer: D, E

n Oracle Solaris 11, you can use the deduplication (dedup) property to remove redundant data from your ZFS file systems. If a file system has the dedup property enabled, duplicate data blocks are removed synchronously. The result is that only unique data is stored, and common components are shared between files.
