The appropriate NetApp feature to use in this scenario is aCloud Storage Pool. A Cloud Storage Pool in NetApp StorageGRID allows the administrator to tier data to public clouds like Amazon S3 Glacier Deep Archive. This feature lets the administrator keep local replicated copies for performance, geo-dispersederasure-coded copies for durability, and tier cold or backup data to Glacier for long-term retention and cost savings.

FabricPool (B)andFlash Pool (C)are not relevant to S3 data tiering and bucket replication in StorageGRID.Dynamic Disk Pool (D)is more applicable to disk management in traditional storage arrays, not for managing S3 bucket replicas across different storage locations.
