A company is building an Amazon Connect contact center and defining a disaster recovery strategy across AWS Regions. The contact center includes dozens of contact flows, hundreds of users, and dozens of claimed phone numbers. Which DR approach yields the LOWEST recovery time objective (RTO)?

Correct answer: Pre-provision a new Amazon Connect instance with all existing users and contact flows in a second Region. Use a Route 53 health check for the Connect URL and a CloudWatch alarm for failures. Create a Lambda function that deploys a CloudFormation template to provision claimed phone numbers when the alarm triggers..
Why this is the answer
The correct option offers the lowest RTO because it pre-provisions the most critical components (instance, users, contact flows) in the secondary region. Route 53 health checks and CloudWatch alarms provide automated, near real-time detection of primary region failures. The Lambda function then automates the final step of provisioning claimed phone numbers, minimizing manual intervention and recovery time.
The other options involve more manual steps or delay the provisioning of critical components. Manually provisioning a new instance or deploying contact flows and users after an outage significantly increases RTO. Delaying the provisioning of users or contact flows until after a failure also prolongs the recovery process, as these are essential for the contact center to function.
