Explanation

Answer D is incorrect; Cache in device RAM Requirement An appropriate amount of physical memory on the machine. The cache is stored in client RAM. The maximum size of the cache is fixed by a setting in the vDisk properties screen. RAM cache is faster than other cache types and works in an HA environment. The RAM is allocated at boot and never changes. The RAM allocated can't be used by the OS. If the workload has exhausted the RAM cache size, the system may become unusable and even crash. It is important to pre-calculate workload requirements and set the appropriate RAM size. Cache in device RAM does not require a local hard drive. Correct answer is B: On the local disk of both provisioning services servers. Requirements Enough space allocated to where the server cache will be stored. Server cache is stored in a file on the server, or on a share, SAN, or other location. The file size grows, as needed, but never gets larger than the original vDisk, and frequently not larger than the free space on the original vDisk. It is slower than RAM cache because all reads/writes have to go to the server and be read from a file. The cache gets deleted when the device reboots, that is, on every boot, the device reverts to the base image. Changes remain only during a single boot session. Server cache works in an HA environment if all server cache locations to resolve to the same physical storage location. This cache type is not recommended for a production More information: https://support.citrix.com/article/CTX119469 Cache on Server.
