AWS Certified Cloud Practitioner — Question 389

A company wants an in-memory data store that is compatible with open source in the cloud.

Which AWS service should the company use?

Answer options

• A. Amazon DynamoDB
• B. Amazon ElastiCache
• C. Amazon Elastic Block Store (Amazon EBS)
• D. Amazon Redshift

Correct answer: B

Explanation

Amazon ElastiCache is a fully managed, in-memory data store and cache service that supports open-source engines like Redis and Memcached. Amazon DynamoDB is a NoSQL database, Amazon EBS is a block storage service, and Amazon Redshift is a data warehouse, making Amazon ElastiCache the correct choice for an in-memory, open-source-compatible solution.
