You need to asynchronously replicate only a subset of block blobs from a source storage account in region A to a destination account in region B, preserving version history and using prefix filters. What should you configure?

Object replication policies are designed for asynchronously replicating block blobs between storage accounts, supporting prefix filters and preserving version history. To ensure version history is maintained during replication, blob versioning must be enabled on both the source and destination storage accounts. The object replication policy itself defines the source and destination containers and includes rules for filtering based on prefixes. Enabling the storage change feed on the destination account is for tracking changes, not for replication. GRS (Geo-redundant storage) provides redundancy within Azure but doesn't offer granular control over replication of specific subsets or version preservation across accounts. Azure Data Factory could copy blobs but wouldn't inherently preserve version history or be the most efficient solution for this specific scenario compared to native object replication.
