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 (&B) 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
