Which set of strategies should the solutions architect use?
A. Build the application in a single AWS Region. Deploy the EC2 application layer to three Availably Zones using an Auto Scaling group with dynamic scaling based on request metrics. Use a Multi-AZ Amazon Aurora MySQL DB duster with two Aurora Replicas. Each Aurora Replica must have enough capacity to support 50% of the peak read queries.
B. Build the application in a single AWS Region. Deploy the EC2 application layer to three Availability Zones using an Auto Scaling group with a minimum desired capacity sufficient to process 450.000 requests each minute. Use a Multi-AZ Amazon Aurora MySQL DB duster with two Aurora Replicas. Each Aurora Replica must have enough capacity to support 100% of the peak read queries.
C. Build the application in two AWS Regions Deploy the EC2 application layer to two Availability Zones using an Auto Scaling group with dynamic scaling based on the request metrics in each Region. In the second Region, deploy an Amazon Aurora MySQL cross-Region replica. Use Amazon Route 53 to distribute traffic between Regions and configure failover if a Region becomes unavailable.
D. Build the application in a single AWS Region. Deploy the EC2 application layer to two Availability Zones using an Auto Scaling group with a minimum desired capacity sufficient to process 300.000 requests each minute. Use a Multi-AZ Amazon Aurora MySQL DB cluster with one Aurora Replica. The Aurora Replica must have enough capacity to support 50% of the peak read and write queries.
