AWS Certified Cloud Practitioner — Question 797

A company wants a key-value NoSQL database that is fully managed and serverless.

Which AWS service will meet these requirements?

Answer options

• A. Amazon DynamoDB
• B. Amazon RDS
• C. Amazon Aurora
• D. Amazon MemoryDB for Redis

Correct answer: A

Explanation

Amazon DynamoDB is a fully managed, serverless NoSQL database service that natively supports key-value and document data structures. In contrast, Amazon RDS and Amazon Aurora are relational database services, while Amazon MemoryDB for Redis is an in-memory database service that is not serverless.
