You have started a new job and are reviewing your company’s infrastructure on AWS. You notice one web application
where they have an Elastic Load Balancer (ELB) in front of web instances in an Auto Scaling Group. When you check
the metrics for the ELB in CloudWatch you see four healthy instances. In Availability Zone (AZ) A and zero in AZ B There
are zero unhealthy instances. What do you need to fix to balance the instances across AZs?
Set the ELB to only be attached to another AZ
Make sure Auto Scaling is configured to launch in both AZs
Make sure your AMI is available in both AZs
Make sure the maximum size of the Auto Scaling Group is greater than 4
