AWS Certified Cloud Practitioner — Question 401

A cloud practitioner needs to design a NoSQL database that is highly scalable, is durable, and requires minimal maintenance.

Which AWS service meets these requirements?

Answer options

• A. Amazon RDS for MySQL
• B. Microsoft SQL Server on Amazon EC2
• C. Amazon DynamoDB
• D. Amazon Redshift

Correct answer: C

Explanation

Amazon DynamoDB is a fully managed, serverless NoSQL database service that provides high durability, seamless scalability, and requires minimal maintenance. In contrast, Amazon RDS for MySQL and SQL Server on EC2 are relational (SQL) databases, and Amazon Redshift is a data warehousing service, none of which meet the NoSQL requirement.
