Management wants to improve read performance and availability while controlling cost and making as few application changes as possible. Which solution meets these requirements?

  • Enable a Multi-AZ deployment and upgrade the primary instance to db.m6i.2xlarge.

  • Migrate the database to Amazon Aurora MySQL Serverless v2 and use two Aurora Replicas.
