According to NetApp, which two scenarios are recommended for a RAID-DP aggregate in clustered Data ONTAP 8.3? (Choose two.)
A. three or more disks if it is a data aggregate
B. three or more disks if it is a root aggregate
C. two or more disks if it is a root aggregate
D. five or more disks if it is a data aggregate
Correct Answer: BD
Explanation/Reference:
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 (dParity) disk.
However, for non-root aggregates with only one RAID group, you must have at least 5 disks (three data disks and two parity disks).
