AWS Certified Data Engineer Associate DEA-C01 Practice Question

An online retailer is migrating a 100-GB MySQL OLTP database to AWS. Read traffic can spike 20x for a few hours during flash sales, then falls below 10% most of the day. The team requires sub-50 ms latency and wants to minimize cost by avoiding over-provisioning. Which Amazon RDS configuration best meets these needs?

  • Amazon RDS for MySQL primary instance with read replicas that are added or removed by an Auto Scaling policy.

  • Amazon Aurora MySQL provisioned cluster with one writer and two Aurora Replicas sized for flash-sale traffic.

  • Amazon RDS for MySQL Multi-AZ deployment with Provisioned IOPS storage sized for peak demand.

  • Amazon Aurora Serverless v2 (MySQL-compatible) cluster with a minimum and maximum Aurora Capacity Unit range.
