Explanation:
Disk1: NTFS only
Disk2: NTFS or ReFS only
The Windows Server Hybrid Core Infrastructure objectives specify that disk (volume) quotas-the classic per- user/per-volume quota feature exposed in the volume's properties-are a capability of NTFS. The guidance states that "NTFS supports user and volume quotas that can be configured per volume; ReFS does not implement the legacy NTFS disk-quota mechanism." Therefore, to meet the requirement that Disk1 must support disk-level quotas, the volume must be formatted as NTFS.
For Data Deduplication, the storage module explains that Data Deduplication is a file-system feature available on modern Windows Server versions and that it is "supported on NTFS volumes and on ReFS volumes beginning with Windows Se rver 2019/2022 scenarios." The same materials emphasize that exFAT doesn't support Windows Server features such as quotas or dedup. Consequently, to satisfy the requirement that Disk2 must support Data Deduplication, you can format Disk2 as NTFS or ReFS; both file systems are valid for dedup workloads on current Windows Server releases, while exFAT is not.
Thus:
* Disk1 # NTFS only (to enable disk-level quotas).
* Disk2 # NTFS or ReFS only (to enable Data Deduplication).
