D: Azure Storage offers two options for copying your data to a secondary region:
-> Geo-redundant storage (GRS)
-> Geo-zone-redundant storage (GZRS)
B: With GRS or GZRS, the data in the secondary region isn't available for read or write access unless there is a failover to the secondary region. For read access to the secondary region, configure your storage account to use read-access geo-redundant storage (RA-GRS) or read-access geo-zone-redundant storage (RA-GZRS).
https://docs.microsoft.com/en-us/azure/storage/common/storage-redundancy#redundancy-in-a-secondary-regionTo create an Azure Storage account that replicates data outside the Azure region automatically, you can use one of the following two options:
Geo-redundant storage (GRS): GRS creates multiple copies of your data and stores them in two different regions. The primary region is where the storage account is created, and the secondary region is another region that is geographically distant from the primary region. GRS automatically replicates data to the secondary region asynchronously. GRS provides read-only access to data in the secondary region if the primary region is unavailable. However, GRS may incur additional costs compared to other storage options.
Read-access geo-redundant storage (RA-GRS): RA-GRS provides the same level of redundancy as GRS, with the additional benefit of allowing read access to the secondary region. This means that you can read data from the secondary region even if the primary region is unavailable. RA-GRS is more expensive than GRS but can be useful for scenarios where you need to minimize downtime and ensure that your data is always available.
The other two options, zone-redundant storage (ZRS) and locally-redundant storage (LRS), do not provide automatic replication of data outside the Azure region.
ZRS stores multiple copies of data within a single region across different availability zones, providing a higher level of availability and durability than LRS, which only stores multiple copies of data within a single data center. However, neither of these options provides automatic replication of data to another region outside of the Azure region where the storage account is created.
