Which feature is described below?
You can use the ___ to reduce the number of duplicate blocks of data in storage, you can store much more
data in a given amount of storage capacity than was possible in previous releases that used Single Instance
Storage (SIS) or NTFS file system compression.

A.
iSCSI Target Server

B.
iSCSI Target Boot

C.
Multiterabyte Volumes

D.
Data Deduplication role service

Explanation:
By using Data Deduplication, general purpose file servers can typically reduce storage capacity utilization by a
2:1 ratio (for example, files that previously used 1 TB would use 500 GB after deduplication). Servers that host
virtualization data (such as VHD files) often reduce storage capacity utilization by a 20:1 ratio, which reduces 1
TB of data to 50 GB.
