Microsoft Azure Administrator Associate AZ-104 Practice Question

Geo-zone-redundant storage (GZRS) is the correct choice because it combines zone redundancy within a primary region and geo-redundancy across regions. GZRS synchronously replicates data across three Azure availability zones in the primary region, protecting against data center failures within that region. It also asynchronously replicates data to a secondary geographic region, protecting against regional outages. This provides both intra-region and inter-region redundancy for the highest availability and durability of mission-critical data.

Geo-redundant storage (GRS) replicates data across regions but does not provide zone redundancy within the primary region. Zone-redundant storage (ZRS) offers redundancy across availability zones in the primary region but does not replicate data to a secondary region. Locally-redundant storage (LRS) replicates data within a single data center and does not protect against data center or regional failures.
