AWS Certified Cloud Practitioner — Question 334

A company is building an application that will receive millions of database queries each second. The company needs the data store for the application to scale to meet these needs.

Which AWS service will meet this requirement?

Answer options

Correct answer: A

Explanation

Amazon DynamoDB is a fully managed NoSQL database service that offers single-digit millisecond latency at any scale, making it ideal for handling millions of queries per second. AWS Cloud9 is an integrated development environment (IDE) rather than a database service, and Amazon Neptune is a graph database not designed for this type of high-throughput key-value workload. Amazon Elastic ache for Memcached is an in-memory cache, but DynamoDB is the primary data store designed to scale seamlessly for this volume of database queries.
