Question

A company runs a web application on Amazon EC2 instances in an Auto Scaling group behind an Application Load Balancer (ALB). The application stores data in an Amazon Aurora MySQL DB cluster. The company needs to create a disaster recovery (DR) solution. The acceptable recovery time for the DR solution is up to 30 minutes. The DR solution does not need to support customer usage when the primary infrastructure is healthy. Which solution will meet these requirements?

Accepted Answer

Correct answer: A. The correct answer is A. Option A: Deploy the DR infrastructure in a second AWS Region with an ALB and an Auto Scaling group. Set the desired capacity and maximum capacity of the Auto Scaling group to a minimum value. Convert the Aurora MySQL DB cluste... Auto Scaling adjusts capacity automatically to match demand, improving availability and cost efficiency. Amazon Aurora is a high-performance managed relational database with built-in replication and failover. Amazon Route 53 provides DNS with health checks and routing policies for availability and latency. By spanning multiple Availability Zones / adding redundancy, this option provides the high availability and resilience required.
