A multinational corporation is planning to deploy a critical application on Azure that will store sensitive business data. The application must ensure high availability and durability of data across regional outages while providing low latency access to users distributed globally. The corporation is also concerned about cost-effectiveness and compliance with data sovereignty laws. Considering these requirements, which Azure Storage redundancy option should be chosen to best meet the needs? (Choose two correct options)
A
Locally Redundant Storage (LRS) - Replicates your data three times within a single data center in a single region. This option is cost-effective but does not protect against regional outages.
B
Zone-Redundant Storage (ZRS) - Replicates your data synchronously across three Azure availability zones in the primary region. It offers higher durability than LRS but does not provide geo-redundancy.
C
Geo-Redundant Storage (GRS) - Replicates your data to a secondary region that is hundreds of miles away from the primary region. It provides protection against regional outages but does not allow read access to the data in the secondary region unless there is a failover.
D
Read-Access Geo-Zone-Redundant Storage (RA-GZRS) - Combines the high availability provided by ZRS with the geo-redundancy of GRS, allowing read access to the data in the secondary region. This option ensures durability, high availability, and low latency access across regions.
E
Geo-Zone-Redundant Storage (GZRS) - Similar to RA-GZRS but does not allow read access to the secondary region. It provides a balance between cost and redundancy.
