Scenario: A Citrix Architect is designing a multi-server Provisioning Services solution for CGE. The solution must be highly available and minimize the risk of vDisk inconsistency. Why does…
The correct answer is A. It provides striping and the highest performance. RAID 10 combines striping and mirroring to deliver excellent performance and fault tolerance, making it ideal for high-availability PVS solutions that require fast vDisk access and data redundancy.

Why each option
RAID 10 combines striping and mirroring to deliver excellent performance and fault tolerance, making it ideal for high-availability PVS solutions that require fast vDisk access and data redundancy.
RAID 10 (RAID 1+0) is implemented as a striped set of mirrored disks. It leverages striping to achieve high read/write performance by distributing data across multiple disks, which is critical for high-volume vDisk I/O in a PVS environment.
RAID 10 does not minimize disk space; it uses 50% of the total disk capacity for mirroring, which is not space-efficient.
RAID 10 does not minimize disk space; it uses 50% of the total disk capacity for mirroring.
While RAID 10 does provide both fault tolerance and high performance, choice A is a more direct explanation for *how* it achieves that performance, by explicitly mentioning the striping mechanism inherent to its design.
