Microsoft Azure Data Fundamentals — Question 251

Which type of non-relational data store supports a flexible schema, stores data as JSON files, and stores the all the data for an entity in the same document?

Answer options

• A. document
• B. columnar
• C. graph
• D. time series

Correct answer: A

Explanation

The correct answer is 'document' because document stores are designed to handle flexible schemas and store data as JSON files, allowing all relevant entity data to reside in one document. The other options, such as columnar, graph, and time series, do not support this document-centric structure.
