Which combination of steps will meet these requirements?
(Choose two.)
Add another Region to the Aurora MySQL DB cluster
Add another Region to each table in the Aurora MySQL DB cluster
Set up scheduled cross-Region backups for the DynamoDB table and the Aurora MySQL DB cluster
Convert the existing DynamoDB table to a global table by adding another Region to its configuration
Use Amazon Route 53 Application Recovery Controller to automate database backup and recovery to the secondary Region
Explanations:
Adding another Region to the Aurora MySQL DB cluster using Aurora Global Databases allows for low-latency cross-region replication, fulfilling the requirement for multi-region deployment and ensuring RTO and RPO are within the defined limits.
Aurora MySQL Global Databases do not support adding a Region to individual tables. The feature operates at the cluster level, not on a per-table basis.
Scheduled cross-Region backups do not provide real-time replication or satisfy the RTO and RPO requirements of a few minutes. They are typically used for disaster recovery, not active multi-region deployment.
Converting the existing DynamoDB table to a global table enables cross-region replication, ensuring the DynamoDB data is available in multiple regions and compliant with the company’s policy for high availability and low RTO/RPO.
Route 53 Application Recovery Controller is designed for failover management, not for replicating or backing up databases across Regions. It doesn’t meet the requirement of real-time or near-real-time replication for critical applications.
If memory serves me right, the answer is:
Add another Region to the Aurora MySQL DB cluster
