A company has 10 web server Amazon EC2 instances that run in an Auto Scaling group in a production VPC. The company has 10 other web servers that run in an on-premises data center. The company has a 10 Gbps AWS Direct Connect connection between the on-premises data center and the production VPC. The company needs to implement a load balancing solution that receives HTTPS traffic from thousands of external users. The solution must distribute the traffic across the web servers on AWS and the web servers in the on-premises data center. Regardless of the location of the web servers, HTTPS requests must go to the same web server throughout the entire session. Which solution will meet these requirements?

Chose B1
Something is wrong with question or answers. When you create target groups you can specify the target type either: 1) Instances ( and here you can add also EC2 scaling groups) 2) IP Address ( Supports load balancing to VPC and on-premises resources. ) But when you have both EC2 scaling and on-prem IP what can you do ? Plus it is saying "receives HTTPS traffic from thousands of external users" which implies that autoscale should work to accommodate. A very complex solution will be to have ALB in ALB meaning that in the target groups of first ALB you will have IP of the on-prem server and the IP of a load-balancer which includes the EC2 auto-scalling group but it's kinda a nightmare to proper manage this thing but technically possible. So only because of that i will go for B but i strongly believe something is wrong with the question.
