The scenario involves storing text files, videos, audio streams, and virtual disk images, along with metadata and a unique ID. This exactly matches Object storage characteristics:
* Stores large amounts of unstructured data (blobs).
* Each object contains the data itself, metadata, and a unique identifier.
* Azure Blob Storage is Microsoft's object storage solution.
Other options:
* Columnar # Used for analytics workloads, optimized for reading columns (e.g., data warehouses).
* Key/Value # Good for simple lookups but not optimized for storing large multimedia files.
* Document # Stores semi-structured JSON documents, not large binary objects.
Thus, the correct answer is Object storage.
