Topic 1 Question 69
A financial services company in North America plans to release a new online web application to its customers on AWS. The company will launch the application in the us-east-1 Region on Amazon EC2 instances. The application must be highly available and must dynamically scale to meet user traffic. The company also wants to implement a disaster recovery environment for the application in the us-west-1 Region by using active-passive failover.
Which solution will meet these requirements?
Create a VPC in us-east-1 and a VPC in us-west-1. Configure VPC peering. In the us-east-1 VPC, create an Application Load Balancer (ALB) that extends across multiple Availability Zones in both VPCs. Create an Auto Scaling group that deploys the EC2 instances across the multiple Availability Zones in both VPCs. Place the Auto Scaling group behind the ALB.

The correct answer is C. Choice C meets the requirements for the application to be highly available and to dynamically scale to meet user traffic, as well as implementing a disaster recovery environment in the us-west-1 Region through active-passive failover.
In choice C, the company creates a VPC in us-east-1 and a VPC in us-west-1, and sets up an Application Load Balancer (ALB) and Auto Scaling group in both VPCs. The ALB extends across multiple Availability Zones in each VPC, and the Auto Scaling group deploys the EC2 instances across these Availability Zones. The Auto Scaling group is placed behind the ALB, which allows for automatic scaling of the instances to meet user traffic.
An Amazon Route 53 hosted zone is also created, with separate records for each ALB. Health checks are enabled for each record, and a failover routing policy is configured. This allows for active-passive failover between the two regions, ensuring high availability for the application.

active-passive failover==>a failover routing policy within route 53
👍 4zozza20232023/01/30 C is correct
