The file extension is not specified randomly, but with a purpose, namely to highlight the type of files. File3.sys implies from the start that it is a system file. Server1: - File1.txt, File2.doc, File3.sys, and File4.bmp Server2: - File1.txt and File3.sys only File1.txt : is not deduplicated (size less than 32kb) File3.sys : is not deduplicated (system file) Data deduplication is supported only on the following: - Windows Server operating systems beginning with Windows Server 2012 - NTFS data volumes - Cluster shared volume file system (CSVFS) supporting virtual desktop infrastructure (VDI) workloads beginning with Windows Server 2012 R2 Deduplication skips over the following files: - System-state files - Encrypted files - Files with extended attributes - Files whose size is less than 32 KB - Reparse points (that are not data deduplication reparse points) https://learn.microsoft.com/en-us/previous-versions/windows/desktop/dedup/about-data-deduplication

Hmm, dedup is not forward compatible, so no sure the 2019 server would be able deal with the 2022 deduped data disk.

Deduplication skips over system state files. The .sys extension is usually used for operating system files. So if they're trying to imply that File3.sys is a system file, that would be ignored by deduplication, so the answer would be Server 2: File1.txt and File3.sys?

Correct. option 1, all files (because of the already installed dedup feature) and option 2, file1 and file3.
