Question 53

A solutions architect must create a disaster recovery (DR) plan for a high-volume software as a service (SaaS) platform. All data for the platform is stored in an Amazon Aurora MySQL DB cluster. The DR plan must replicate data to a secondary AWS Region. Which solution will meet these requirements MOST cost-effectively?
  • A Use AWS Database Migration Service (AWS DMS) to continuously replicate data to an Aurora cluster in the secondary Region. Remove the DB instance from the secondary Region.
  • B Use MySQL binary log replication to an Aurora cluster in the secondary Region. Provision one DB instance for the Aurora cluster in the secondary Region.
  • C Set up an Aurora global database for the DB cluster. When setup is complete, remove the DB instance from the secondary Region.
  • D Set up an Aurora global database for the DB cluster. Specify a minimum of one DB instance in the secondary Region.
