AWS Certified Cloud Practitioner — Question 447

A company is designing an application. For the data persistence layer, the company wants to use a NoSQL database.

Which AWS service should the company use for the database?

Answer options

• A. Amazon Redshift
• B. AWS DataSync
• C. Amazon Athena
• D. Amazon DynamoDB

Correct answer: D

Explanation

Amazon DynamoDB is a fully managed, serverless NoSQL database service provided by AWS that delivers fast and predictable performance. Amazon Redshift is a data warehousing service, Amazon Athena is an interactive query service for S3, and AWS DataSync is a data transfer service, making them unsuitable for NoSQL database persistence.
