• B

• C

Explanation

Option B is not correct because monitoring the health of the EC2 instances is not sufficient to provide failover as the EC2 instances are in an Auto Scaling group and instances can be added or removed dynamically. Option C is not correct because monitoring the private IP address of an EC2 instance is not sufficient to determine the health of the infrastructure, as the instance may still be running but the application or service on the instance may be unhealthy. Option E is not correct because simple routing does not take into account geographic proximity, which is a requirement in this scenario.
