AWS Certified Developer Associate DVA-C02 Practice Question

An e-commerce site hosted on AWS uses Amazon RDS MySQL to store product catalog data. During seasonal sales events, the application experiences high read latency because the same catalog queries are executed thousands of times per second. The development team wants a fully managed service that can keep transient, in-memory copies of this frequently requested data to reduce latency and offload reads from RDS. Which service should they implement?

  • Amazon ElastiCache for Redis

  • Amazon DynamoDB Accelerator (DAX)

  • Amazon RDS read replica

  • Amazon CloudFront
