Which RAID configuration must the administrator use in this storage policy to achieve the best performance for the database virtual machines?

An administrator has deployed a new vSAN cluster that contains eight hosts and needs to configure a storage policy for the currently deployed database virtual machines. The requirements state that if two hosts in the vSAN cluster fail, all virtual machines are unaffected.

Which RAID configuration must the administrator use in this storage policy to achieve the best performance for the database virtual machines?
A . RAID-0
B. RAID-6
C. RAID-5
D. RAID-1

Answer: B

Explanation:

The RAID configuration that the administrator must use in this storage policy to achieve the best performance for the database virtual machines is RAID-6.

RAID-6 is an effective configuration for a vSAN cluster with eight hosts as it allows for two hosts to fail and still maintain protection of the data. RAID-6 is a data striping configuration with two parity bits stored across multiple disks, which improves read performance while also providing fault tolerance.
