Step-by-step explanation:
The question pertains to which services provided by Microsoft Azure allow customers to store semi-structured datasets. Among the options given:
- Azure File Storage is meant for shared file storage using the standard SMB protocol.
- Azure SQL Database is a relational database service based on SQL Server and does not primarily store semi-structured data.
- Azure Blob Storage is optimized for storing massive amounts of unstructured data, such as text or binary data, which can include semi-structured data.
- Azure SQL Data Warehouse (now part of Azure Synapse Analytics) is an analytics service that can handle large volumes of structured and semi-structured data.
