A Solutions Architect just completed the implementation of a 2-tier web application for a client. The application uses Amazon EC2 instances, Amazon ELB and Auto Scaling across two subnets. After deployment the Solutions Architect noticed that only one subnet has EC2 instances running in it. What might be the cause of this situation?. The Auto Scaling Group has not been configured with multiple subnets. The ELB is configured as an internal-only load balancer. Cross-zone load balancing is not enabled on the ELB. The AMI is missing from the ASG’s launch configuration.

A Solutions Architect created a new subnet in an Amazon VPC and launched an Amazon EC2 instance into it.
