Scenario: A Citrix Architect is designing a new Citrix Virtual Apps and Desktops environment. Citrix Provisioning (PVS) has been selected for image management.
The PVS vDisk store requires high fault tolerance and the ability to support dual drive failure.
Which RAID level could the architect use for the PVS vDisk store?
To meet the requirements of high fault tolerance and the ability to support dual drive failure, RAID 6 is the suitable choice. RAID 6 offers fault tolerance and can continue to operate even if two drives fail simultaneously, making it more resilient and reliable for critical data storage like a Citrix Provisioning vDisk store.
RAID 6 support dual drive failure.
B. RAID 6
A RAID 6 array--also referred to as dual drive failure protection- https://docs.oracle.com/cd/E19871-01/820-1847-20/appendixf.html#:~:text=RAID%206%20arrays%20provide%20extra,two%20simultaneous%20disk%20drive%20failures.
Easiest question of the whole exam :D
