Microsoft Azure Data Fundamentals — Question 21

Your company is designing an application that will write a high volume of JSON data and will have an application-defined schema.
Which type of data store should you use?

Answer options

• A. columnar
• B. key/value
• C. document
• D. graph

Correct answer: C

Explanation

The correct choice is C, document, as it is designed to handle semi-structured data like JSON and allows for an application-defined schema. Options A (columnar) and D (graph) are not suitable for JSON data storage, while B (key/value) lacks the structure needed for application-defined schemas.
