In an aggregate using a RAID-DP raid group, what is the minimum number of disks that are needed to create an aggregate so that it contains three data disks?
A.
9 disks
B.
7 disks
C.
3 disks
D.
5 disks
Explanation:
The minimum number of disks in a RAID-DP group is three: at least one data disk, one regular parity disk, and one double-parity (or dParity) disk. If there is a datadisk or parity-disk failure in a RAID-DP group, Data ONTAP replaces the failed disk in the RAID group with a spare disk and uses the parity data to reconstruct the
data of the failed disk on the replacement disk. If there is a double-disk failure, Data ONTAP replaces the failed disks in the RAID group with two spare disks and
uses the double-parity data to reconstruct the data of the failed disks on the replacement disks.
RAID-DP is the default RAID type for all aggregates.
D
If the aggregate contains 3 data disks it’s size must be 5.

that info is wrong the minimum is 5 and it is on Cluster ONTAP fundamentals course
