Correct Answer: Box 1: Zone-redundant storage (ZRS) Zone-redundant storage (ZRS) replicates your data synchronously across three storage clusters in a single Region. GRS protects against Zone failure, while ZRS protects against data center failure. LRS would not remain available if a data center in the region fails. GRS and RA GRS use asynchronous replication. Box 2: StorageV2 (general purpose V2) ZRS only support GPv2.

The thing is that ZRG is not Geo-redundant. it merely works within a single region.

ZRS means Zone Redundant, the only think to Introduce a G here, is if was asked about "Region Failover" Whenever you hear a "Datacenter"; It is Z over there

Is that only me cannot understand whether below from Microsoft Doc means ZRS is supported or not supported by BLOB: "ZRS is supported for all Azure Storage services through standard general-purpose v2 storage accounts, including: Azure Blob storage (hot and cool block blobs and append blobs, non-disk page blobs), Azure Files (all standard tiers: transaction optimized, hot, and cool), Azure Table storage, Azure Queue storage"

For reference, when people say the likes of "ZRS only support GPv2", this is not true (or perhaps no longer true). ZRS does support Premium Blob and Premium File Share 'in some regions', but these are not an option in the question. https://learn.microsoft.com/en-us/azure/storage/common/storage-account-overview
