Microsoft Azure Data Fundamentals — Question 25

You need to recommend a non-relational data store that is optimized for storing and retrieving text files, videos, audio streams, and virtual disk images. The data store must store data, some metadata, and a unique ID for each file.
Which type of data store should you recommend?

Answer options

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

Correct answer: C

Explanation

The correct answer is C, object data stores are designed to manage large amounts of unstructured data, such as files and media, along with their metadata and unique identifiers. Option A, key/value stores, are more suited for simple data retrievals, while B, columnar stores, are optimized for analytical queries, and D, document stores, are focused on semi-structured data formats, making them less ideal for the stated requirements.
