VMware Carbon Black Cloud Enterprise EDR Specialist — Question 60

An administrator has deployed a new vSAN OSA 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 OSA 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?

Answer options

Correct answer: A

Explanation

RAID-1 is the correct choice because it provides redundancy and allows for the failure of two hosts without data loss, ensuring that virtual machines remain operational. RAID-5 and RAID-6 do not provide the same level of protection against two simultaneous host failures, with RAID-6 allowing for only one additional failure but at a cost of performance. RAID-0 offers no redundancy, making it unsuitable for this scenario.
