Minimizes costs.

B. tables in an Azure Storage account that use geo-redundant storage (GRS)

I believe given answer B is correct Page blobs, which are optimized for random read/write operations, and which provide the ability to write to a range of bytes in a blob. Azure Table storage is a service that stores non-relational structured data (also known as structured NoSQL data) in the cloud, providing a key/attribute store with a schemaless design. Because Table storage is schemaless, it's easy to adapt your data as the needs of your application evolve. Access to Table storage data is fast and cost-effective for many types of applications, and is typically lower in cost than traditional SQL for similar volumes of Follow on next =>

No need mentioned for Read Access on remote replica.

The correct answer is B. Tables in an Azure Storage account that use Geo-redundant storage (GRS). Azure Table Storage offers NoSQL capabilities and provides a key-attribute store with a schema-less design. This makes it a good fit for hosting independent tables of varying sizes and usage patterns. Table Storage data is accessible via REST APIs, and GRS automatically replicates your data to a secondary region to protect against regional outages. As per the cost minimization requirement, GRS is cheaper than RA-GRS, and Azure Table Storage is generally more cost-effective than Azure SQL Database options.

I don't know why table storage is considered as correct. It does not provide flexibility of "usage pattern". There is only a primary key (partition key and row key).

C. Tables in an Azure Storage account that use read-access geo-redundant storage (RA-GRS). Explanation: Azure Storage tables provide REST-based access to data, which meets the requirement of accessing the data using a REST connection. Azure Storage tables can accommodate multiple tables of varying sizes and usage patterns. Read-access geo-redundant storage (RA-GRS) ensures automatic replication of data to a second Azure region, providing data redundancy and disaster recovery capabilities. Azure Storage tables are typically more cost-effective compared to Azure SQL Database, making it a suitable choice for minimizing costs. Option B (Tables in an Azure Storage account that use geo-redundant storage) is not the optimal choice as it does not provide read-access to the replicated data in the second Azure region, which is a requirement in this scenario.

B is the answer. https://learn.microsoft.com/en-us/azure/storage/tables/table-storage-overview Azure Table storage is a service that stores non-relational structured data (also known as structured NoSQL data) in the cloud, providing a key/attribute store with a schemaless design. Because Table storage is schemaless, it's easy to adapt your data as the needs of your application evolve. Access to Table storage data is fast and cost-effective for many types of applications, and is typically lower in cost than traditional SQL for similar volumes of data. https://learn.microsoft.com/en-us/azure/storage/common/storage-redundancy#geo-redundant-storage Geo-redundant storage (GRS) copies your data synchronously three times within a single physical location in the primary region using LRS. It then copies your data asynchronously to a single physical location in a secondary region that is hundreds of miles away from the primary region. GRS offers durability for storage resources of at least 99.99999999999999% (16 9's) over a given year.

: minimize cost GRS!

"20 independent tables of varying sizes and usage patterns" - why is it not an elastic pool ?

B - tables in an Azure Storage account that use geo-redundant storage (GRS) GRS - read from the secondary only in the event of a failover is cheaper than RA GRS - read from the secondary at all times https://azure.microsoft.com/en-us/pricing/details/storage/tables/#pricing

B. tables in an Azure Storage account that use geo-redundant storage (GRS) - is correct. **Automatically replicates the data to a second Azure region - both GRS and RA-GRS do this, but GRS costs LESS than RA-GRS.
