AWS Certified Cloud Practitioner (CLF-C02) — Question 706

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, serverless NoSQL database designed to scale horizontally and handle millions of requests per second with consistent, single-digit millisecond latency. AWS Cloud9 is an integrated development environment (IDE) rather than a database. While Amazon ElastiCache for Memcached is an in-memory store and Amazon Neptune is a graph database, DynamoDB is the primary AWS service engineered to scale as a primary operational data store for millions of queries per second.
