A company hosts parts of a Python-based application using AWS Elastic Beanstalk. An Elastic Beanstalk CLI is being used to create and update the environments. The Operations team detected an increase in requests in one of the Elastic Beanstalk environments that caused downtime overnight. The team noted that the policy used for AWS Auto Scaling is NetworkOut. Based on load testing metrics, the team determined that the application needs to scale CPU utilization to improve the resilience of the environments. The team wants to implement this across all environments automatically. Following AWS recommendations, how should this automation be implemented?

An application runs on Amazon EC2 instances behind an Application Load Balancer. Amazon RDS MySQL is used on the backend. The instances run in an Auto Scaling group across multiple Availability Zones. The Application Load Balancer health check ensures the web servers are operating and able to make read/write SQL connections. Amazon Route 53 provides DNS functionality with a record pointing to the Application Load Balancer. A new policy requires a geographically isolated disaster recovery site with an RTO of 4 hours and an RPO of 15 minutes. Which disaster recovery strategy will require the LEAST amount of changes to the application stack?

A.
Launch a replica stack of everything except RDS in a different Availability Zone. Create an RDS read-only replica in a new Availability Zone and configure the new stack to point to the local RDS instance. Add the new stack to the Route 53 record set with a failover routing policy.
