Answer: Deploy necessary infrastructure and use Route 53 for failover, with an Aurora Replica in a different AWS Region.
Option A is correct because it involves deploying the application with the required infrastructure and using Amazon Route 53 to configure active-passive failover. This needs only one Aurora Replica in a second AWS Region, which meets the given requirements. The solution ensures that up to 30 minutes of downtime and potential data loss are acceptable, without the need to handle the load when the primary infrastructure is healthy, which aligns perfectly with the disaster recovery strategy specified in the question.

A company operates a global web application on EC2 with an Application Load Balancer and uses Amazon Aurora for data storage. They require a disaster recovery setup tolerating 30 minutes of downtime and data loss, without the need for handling traffic during primary operation. What is the appropriate architect solution?
A
Deploy necessary infrastructure and use Route 53 for failover, with an Aurora Replica in a different AWS Region.
B
Maintain a reduced-scale application copy in another Region, with Route 53 for active-active failover and an Aurora Replica.
C
Duplicate the primary setup in another Region, with Route 53 for active-active failover, restoring an Aurora DB from the latest snapshot.
D
Secure data with AWS Backup, recreate infrastructure in another Region for failover with Route 53, and set up an Aurora primary instance there.
