Correct Answer: BIn a VMware Horizon environment using vSAN as the primary storage, the goal is to consume the least amount of storage possible. Instant Clones are inherently non-persistent and share the same virtual disk with a parent VM, meaning they do not require additional redundancy. Therefore, applying a Fully Tolerant Time (FTT) policy of 0 will utilize the least amount of storage, as it does not replicate the data. This makes FTT=0 the most storage-efficient option for Instant Clone VMs in this vSAN environment.
