A company's AWS-hosted application operates on EC2 instances with an Elastic Load Balancer, within an Auto Scaling group, and uses a DynamoDB table. To achieve minimal downtime and application availability in another AWS Region, what steps should a solutions architect take?
A
Establish an Auto Scaling group and load balancer in the secondary Region, set up a global DynamoDB table, and implement DNS failover for the new Region's load balancer.
B
Develop a CloudFormation template for on-demand launch of EC2 instances, load balancers, and DynamoDB tables, and set up DNS failover for the secondary Region's load balancer.
C
Prepare a CloudFormation template for EC2 instances and a load balancer, make the DynamoDB table globally accessible, and enable DNS failover to the secondary Region's load balancer.
D
In the secondary Region, set up an Auto Scaling group and load balancer, ensure the DynamoDB table is globally accessible, and use a CloudWatch alarm to trigger a Lambda function for updating Route 53 to point to the new load balancer.
