Your network contains an Active Directory domain. The domain contains a new file server named Server1 that runs a Server Core installation of Windows Server
2016.
Server1 has an ReFS-formatted volume D: and NTFS-formatted volume E:. The volumes do not contain any data.
You install the Data Deduplication role service on Server1.
You need to implement Data Deduplication for volumes on D: and E:.
Solution: From Windows PowerShell, you run Format-Volume D: -FileSystem EXFat and Enable-DeDupVolume -Volume D:,E:.

Data deduplication is not supported for certain volumes, such as any volume that is not a NTFS file system or any volume that is smaller than 2 GB.

No, for 2016 only NTFS and ReFS are supported not - ExFat so formatting the D: drive to that volume type is incorrect

I thought dedup for ReFS was only supported as of Server 2019?

As of Server 2016 ver 1709 dedup is supported on ReFS. See: https://docs.microsoft.com/en-us/windows-server/storage/refs/refs-overview#the-following-features-are-available-on-refs-and-ntfs

ReFs is supported only server Core and Nano server since 1709 version of 2016... But this is exFat formatting as i understand?!

Dan is right - only NTFS Volumes are Supported, extfat is also not supported. If you run enable-dedupvolume on ReFs or Extfat volume you get a error: Deduplication is supported on fixed, write-enabled NTFS data volumes and CSV backed by NTFS data volumes. So it's B- No
