Scenario: A Citrix Architect needs to design a new XenApp and XenDesktop environment. Citrix Provisioning Services has been selected for image management.
Which two RAID levels should the architect use for the storage hosting the Provisioning Service write cache? (Choose two.)
For hosting write-intensive workloads, such as the Provisioning Service write cache in a XenApp and XenDesktop environment, it is crucial to use RAID levels that are optimized for write performance and have a low write penalty. RAID 1 offers disk mirroring which provides redundancy but with good write performance. RAID 10 combines the benefits of RAID 1 and RAID 0, providing both redundancy and improved write performance by striping data across mirrored pairs. Therefore, RAID 1 and RAID 10 are the appropriate choices for the storage hosting the Provisioning Service write cache.
B & C are correct: https://docs.citrix.com/en-us/xenapp-and-xendesktop/7-15-ltsr/citrix-vdi-best-practices/design/design-userlayer5.html For hosting write intensive workloads, such as Provisioning Services write cache and Machine Creation Services differencing disks, RAID levels such as RAID 1 or 10 are optimal, as these are optimized for writes and have a low write penalty.
B&C is correct
