C, D & E for me as NetApp Volume Encryption (NVE) volumes can exist in aggregated deduplicated aggregates, however the NVE volumes do not participate in the aggregate deduplication savings (the NVE volumes are ignored).

B, D and E would be my vote Definitely, not A. C and E are the same answer as NetApp Storage Encryption (NSE) uses Self-encrypting drives (SEDs). https://www.netapp.com/cyber-resilience/data-protection/storage-encryption/

Ontap support two types of encryption, software based and hardware based. Software based are NVE (NetApp Volume Encryption) and NAE (NetApp Aggregate Encryption). Hardware using NetApp Storage Encryption (NSE) supporting full disk encryption. All options leaves customer uses storage efficiencies of ONTAP.

I think CDE is right, because if Volumes are encrypted, the you can not earn so much effiencies. Because the Bytes are nearly randome because of the encryption.

Also, data should be encrypted on the fly on SED drives.
