Microsoft Azure Data Fundamentals DP-900 Practice Question

A developer stores customer preference information as JSON documents in Azure Cosmos DB. Which characteristic of semi-structured data does this storage approach rely on?

  • Data must be stored in predefined columns with enforced data types before it can be queried.

  • Each document contains field names that make the data self-describing rather than depending on a fixed table schema.

  • Every field in the document is required to have a fixed length determined at design time.

  • Values are kept in a binary blob that lacks any tags or keys describing the contents.
