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 =>

data. You can use Table storage to store flexible datasets like user data for web applications, address books, device information, or other types of metadata your service requires. You can store any number of entities in a table, and a storage account may contain any number of tables, up to the capacity limit of the storage account. https://learn.microsoft.com/en-us/azure/storage/tables/table-storage-overview Replication is for sure GRS and NOT RA-GRS as no mention of read ONLY and hence one can assume failover with write access

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.

Read Access to the replica is not a requirement! Quite the opposite is the case. It asks for a backup, but with minimized costs, therefore RA-GRS does not meet the scope of the requirement.

RA-GRS is also more expensive than GRS.

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.

I'm a novice in this space, but as I understand, Elastic pools are used for SQL database. Azure Tables refer to NoSQL or structured, non-relational data. This may explain it https://learn.microsoft.com/en-us/azure/storage/tables/table-storage-overview
