A North American company with headquarters on the East Coast is deploying a new web application running on Amazon EC2 in the us-east-1 Region. The application should dynamically scale to meet user demand and maintain resiliency. Additionally, the application must have disaster recovery capabilities in an active-passive configuration with the us-west-1 Region. Which steps should a solutions architect take after creating a VPC in the us-east-1 Region?

B is right To implement disaster recovery in an active-passive configuration, you should deploy the application infrastructure across multiple Availability Zones (AZs) in each Region with the primary region being us-east-1. By having an Application Load Balancer (ALB) spanning multiple AZs in the us-east-1 Region and EC2 instances as part of an Auto Scaling group served by this ALB, you can achieve dynamic scaling to meet user demand. To ensure high availability across both Regions, create an Amazon Route 53 record set with a failover routing policy that directs traffic from the us-west-1 Region to the primary infrastructure in the us-east-1 Region when available. Enable health checks for this Route 53 record set to ensure that traffic is directed away from unhealthy endpoints, providing a seamless user experience while ensuring resiliency and disaster recovery capabilities.
Chose B1
ALB can't span VPCs in different regions, the key statement in B is "Deploy the same solution in us-west-1"

B. Peering is not needed here as we dont need syncing of environments
