Which of the following commands would create a disk group that would offer the maximum in data redundancy?

As DBA for the Rebalance, you have decided that you need to facilitate some redundancy in
your database. Using ASM, you want to create a disk group that will provide for the greatest
amount of redundancy for your ASM data (you do not have advanced SAN mirroring
technology available to you, unfortunately).
Which of the following commands would create a disk group that would offer the maximum in
data redundancy?

Answer: C

Explanation:
No SAN mirroring available means no external redundancy available.
The highest redundancy of ASM is the HIGH redundancy with 3 mirror copies.
