Correct answer: 6.
Why this is the answer
Geo-zone-redundant storage (GZRS) combines the high availability of zone-redundant storage (ZRS) with the disaster recovery capabilities of geo-redundant storage (GRS). ZRS stores three replicas of your data across three Azure availability zones within a primary region. GRS then asynchronously replicates these three copies to a secondary region, where they are also stored in three copies. Therefore, GZRS stores a total of 6 copies of your data: 3 in the primary region (across zones) and 3 in the secondary region (across zones). Options 2, 3, and 12 are incorrect because they do not reflect the combined replication strategy of GZRS.
