Microsoft Azure Data Fundamentals — Question 22

Your company is designing a data store for internet-connected temperature sensors.
The collected data will be used to analyze temperature trends.
Which type of data store should you use?

Answer options

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

Correct answer: B

Explanation

The correct answer is B, time series, because it is specifically designed to handle data that is collected over time, making it ideal for tracking temperature trends. The other options, such as relational and graph databases, are not optimized for time-based data analysis, while columnar databases may not efficiently manage continuous streams of time-stamped data.
