AWS Certified Cloud Practitioner (CLF-C02) — Question 138

A company wants a time-series database service that makes it easier to store and analyze trillions of events each day.

Which AWS service will meet this requirement?

Answer options

• A. Amazon Neptune
• B. Amazon Timestream
• C. Amazon Forecast
• D. Amazon DocumentDB (with MongoDB compatibility)

Correct answer: B

Explanation

Amazon Timestream is specifically designed for time-series data, allowing efficient storage and analysis of large volumes of events. The other services, such as Amazon Neptune and Amazon DocumentDB, are not optimized for time-series workloads, while Amazon Forecast focuses on predictive analytics rather than data storage.
