Geo-redundant storage (GRS) replicates data to a secondary region, providing read access from both primary and secondary locations.

Read-only geo-redundant storage offers read access from the secondary region but may not meet the requirement for primary and secondary read access.

Zone-redundant storage replicates data within a region across availability zones, lacking separate geographic location storage.

Locally redundant storage replicates data within the same region, not meeting the requirement for separate geographic locations.
