Content Domain 3: Cloud Technology and Services

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?

  • A Amazon DynamoDB
  • B AWS Cloud9
  • C Amazon ElastiCache for Memcached
  • D Amazon Neptune
Explanation

Amazon DynamoDB is a fully managed, serverless key-value and document database built to automatically scale throughput and storage to handle millions of requests per second with consistent, low-latency performance. AWS Cloud9 is a cloud IDE, Amazon ElastiCache for Memcached is an in-memory cache rather than a durable primary data store, and Amazon Neptune is a graph database not designed as a general-purpose store for this scale of query volume.
