Which Azure storage feature continuously replicates blobs to a paired region for region-disaster durability?
ALocally redundant storage (LRS)
BGeo-redundant storage (GRS / RA-GRS / GZRS)
CPremium block blob storage (single-region)
DCool tier with no replication
Answer & Solution
Correct answer: B. Geo-redundant storage (GRS / RA-GRS / GZRS)
GRS variants replicate to paired regions. LRS stays in one DC. Premium block blob is single-region. Cool tier is an access-tier, not replication.
