Explanation
Enabling Reserve Space (C) ensures dedicated storage is allocated for snapshots so they are never at risk of failing due to capacity constraints, and enabling Extended Statistics (E) is required for Windows clients to enumerate and access snapshots through the Previous Versions interface - without both, the snapshot policy alone is insufficient for the full Windows integration to work. Space Reclaim (A) is a separate feature for recovering freed blocks (UNMAP/TRIM), which has nothing to do with snapshot scheduling or Windows visibility. Quota Exceeded Behavior (B) governs what happens when a user hits a storage quota limit - unrelated to snapshot configuration. Atomic Test and Set (D) is a SCSI locking primitive used in VMware/block storage environments, not a NAS file system snapshot concept.
Memory tip: Think "RE-sources for REcovery" - Reserve space and Extended statistics are the two file system properties you must enable so Windows clients can reach back in time via Previous Versions; the Protection Policy handles when snapshots happen, but these two settings handle how Windows sees them.
