Microsoft Azure Administrator Associate AZ-104 Practice Question
Your organization needs to store data in Azure with high availability and durability, ensuring protection against both availability zone failures and complete regional outages. The solution must replicate data synchronously across zones and also provide replication to a secondary region. Which storage replication option should you choose to meet these requirements?
GZRS (Geo-Zone-Redundant Storage) replicates your data synchronously across availability zones within the primary region and asynchronously to a secondary region, providing protection against both zonal and regional failures. This ensures that your data remains highly available and durable even if an entire region becomes unavailable.
ZRS (Zone-Redundant Storage) replicates data synchronously across availability zones but does not replicate to a secondary region, so it does not protect against regional outages. GRS (Geo-Redundant Storage) replicates data to a secondary region but only stores data in a single zone in the primary region, lacking protection against zonal failures. LRS (Locally Redundant Storage) stores multiple copies of data within a single data center, offering the least redundancy.
