Pass4sure NS0-157 Question Answer

When creating a data aggregate, what is the default minimum number of disks for RAID4 and RAID-DP?

A. 5 for RAID4 and 9 for RAID-DP
B. 4 for RAID4 and 7 for RAID-DP
C. 3 for RAID4 and 5 for RAID-DP
D. 2 for RAID4 and 3 for RAID-DP

Answer: D

Explanation: If a root volume exists as a traditional volume, it can be a stand-alone RAID4 or RAID-DP volume. RAID4 requires a minimum of two disks and can protect against single-disk failures. RAID-DP, the default RAID type, requires a minimum of three disks and can protect against double-disk failures. Using RAID-DP for the root aggregate is recommended.
