You are deploying Storage Spaces Direct on four Windows Server 2022 nodes: two nodes per rack. Each node has NVMe and HDD devices. You must ensure: (1) copies of data span racks for fault domain awareness, (2) the VM workload can tolerate a single-node failure with good write performance, and (3) NVMe devices are used for caching. What should you configure? (Choose two)

Correct answer: Define two rack fault domains and assign nodes accordingly before creating volumes., Create volumes using three-way mirror resiliency..
Why this is the answer
Defining two rack fault domains and assigning nodes ensures that copies of data are distributed across racks, meeting the requirement for fault domain awareness. This configuration allows the cluster to tolerate a complete rack failure. Creating volumes with three-way mirror resiliency ensures that there are three copies of data, allowing the workload to tolerate a single-node failure while maintaining good write performance. Three-way mirroring also inherently uses NVMe devices for caching when available, fulfilling that requirement. Dual-parity resiliency would have worse write performance than three-way mirroring. Disabling the cache would negatively impact performance and not utilize the NVMe devices for their intended purpose. Two-way mirror resiliency would not tolerate a single-node failure if that node held one of the two copies, and would not provide the desired fault tolerance.
