Which Azure storage replication option keeps 6 copies of data — 3 in the primary region and 3 in a paired region — to survive a regional disaster?
ALocally redundant storage (LRS)
BGeo-redundant storage (GRS)
CZone-redundant storage (ZRS)
DPremium SSD (no replication)
Answer & Solution
Correct answer: B. Geo-redundant storage (GRS)
GRS replicates to a paired region for region-failure durability. LRS = 3 copies in one DC. ZRS = 3 zones in one region. Premium SSD is a performance tier, not a replication strategy.
