-
A

D
Zone Redundant Storage (ZRS)
Reveal correct answer
Correct answer: B
A.
Locally Redundant Storage (LRS) is a storage redundancy option in Azure where data is replicated three times within a single datacenter in the same region. It does not provide replication to a paired region for disaster recovery purposes.
B.
Geo-Redundant Storage (GRS) is a storage redundancy option in Azure that provides asynchronous replication of data to a paired region. It ensures that your data is durable even in the event of a regional outage, allowing for disaster recovery and business continuity.
C.
Read-Access Geo-Redundant Storage (RA-GRS) is an extension of Geo-Redundant Storage (GRS) that provides read access to the secondary (paired) region. While it provides additional functionality, it is not specifically focused on asynchronous replication for disaster recovery.
D.
Zone Redundant Storage (ZRS) is a storage redundancy option in Azure that provides synchronous replication within the same region across multiple availability zones. It does not offer asynchronous replication to a paired region.
