[All AWS Certified Solutions Architect - Professional SAP-C02 Questions]

A company has a critical application in which the data tier is deployed in a single AWS Region. The data tier uses an Amazon DynamoDB table and an Amazon Aurora MySQL DB cluster. The current Aurora MySQL engine version supports a global database. The application tier is already deployed in two Regions.

Company policy states that critical applications must have application tier components and data tier components deployed across two Regions. The RTO and RPO must be no more than a few minutes each. A solutions architect must recommend a solution to make the data tier compliant with company policy.

Which combination of steps will meet these requirements? (Choose two.)

  • A. Add another Region to the Aurora MySQL DB cluster
  • B. Add another Region to each table in the Aurora MySQL DB cluster
  • C. Set up scheduled cross-Region backups for the DynamoDB table and the Aurora MySQL DB cluster
  • D. Convert the existing DynamoDB table to a global table by adding another Region to its configuration
  • E. Use Amazon Route 53 Application Recovery Controller to automate database backup and recovery to the secondary Region

Badly written question: "The RTO and RPO must be no more than a few minutes each." What is few minutes mean? May be it is 2-3 min for me, may be it is 9-10 min for you.

A solves multi region for DB layer. but question also asks for minimum RPO and RTO which means quick uptime of application in case of failure which is possible with backups. https://aws.amazon.com/blogs/database/cost-effective-disaster-recovery-for-amazon-aurora-databases-using-aws-backup/ https://docs.aws.amazon.com/amazondynamodb/latest/developerguide /CrossRegionAccountCopyAWS.html

Hint given is - Aurora MySQL engine version supports a global database which makes this possible - https://d2908q01vomqb2.cloudfront.net/887309d048beef83ad3eabf2a79a64a389ab1c9f/2021/03/08/Aurora-Global-database-2.jpg
