Answer: Provision a new Amazon Connect instance with all existing users and contact flows in a second Region. Create an Amazon Route 53 health check for the URL of the Amazon Connect instance. Create an Amazon CloudWatch alarm for failed health checks. Create an AWS Lambda function to deploy an AWS CloudFormation template that provisions claimed phone numbers. Configure the alarm to invoke the Lambda function.
The answer D involves provisioning a new Amazon Connect instance with all existing users and contact flows in a secondary AWS Region. This setup significantly reduces the Recovery Time Objective (RTO) because much of the configuration work is done ahead of time, meaning that less has to be set up after a disaster event occurs. The critical parts are: 1. **Provisioning the Instance, Users, and Contact Flows**: By already having the Amazon Connect instance with all users and contact flows pre-configured in the secondary region, you save significant time during failover, as these components do not need to be redeployed in an emergency. 2. **Route 53 Health Check and CloudWatch Alarm**: These services continuously monitor the primary region's Connect instance's health, allowing for rapid detection of any issues. 3. **AWS Lambda for Phone Numbers**: Upon detecting an issue through the CloudWatch alarm triggered by the Route 53 health check, an AWS Lambda function is invoked. This function deploys a CloudFormation template that provisions the claimed phone numbers in the secondary region, completing the disaster recovery process. Overall, this solution minimizes the RTO because the system is largely pre-configured and can quickly transition operational components like claimed phone numbers, which completes the switchover process efficiently.

A company is building a call center by using Amazon Connect. The company’s operations team is defining a disaster recovery (DR) strategy across AWS Regions. The contact center has dozens of contact flows, hundreds of users, and dozens of claimed phone numbers. Which solution will provide DR with the LOWEST RTO?
A
Create an AWS Lambda function to check the availability of the Amazon Connect instance and to send a notification to the operations team in case of unavailability. Create an Amazon EventBridge rule to invoke the Lambda function every 5 minutes. After notification, instruct the operations team to use the AWS Management Console to provision a new Amazon Connect instance in a second Region. Deploy the contact flows, users, and claimed phone numbers by using an AWS CloudFormation template.
B
Provision a new Amazon Connect instance with all existing users in a second Region. Create an AWS Lambda function to check the availability of the Amazon Connect instance. Create an Amazon EventBridge rule to invoke the Lambda function every 5 minutes. In the event of an issue, configure the Lambda function to deploy an AWS CloudFormation template that provisions contact flows and claimed numbers in the second Region.
C
Provision a new Amazon Connect instance with all existing contact flows and claimed phone numbers in a second Region. Create an Amazon Route 53 health check for the URL of the Amazon Connect instance. Create an Amazon CloudWatch alarm for failed health checks. Create an AWS Lambda function to deploy an AWS CloudFormation template that provisions all users. Configure the alarm to invoke the Lambda function.
D
