Suggested Answer: D 🗳️
Yes, you can configure more than one load balancer with an autoscaling group. Auto Scaling integrates with Elastic Load Balancing to enable you to attach one or more load balancers to an existing Auto Scaling group. After you attach the load balancer, it automatically registers the instances in the group and distributes incoming traffic across the instances.

Answer D is right Although you can attach, multiple Load Balances to a single Autoscaling group, it is rarely used, especially after AWS introduced Application Load Balancer(ALB) with support for Routing Rules(Domain and Path-based) and attaching multiple SSL Certificates for a single load balancer features. For example, few scenarios where it was required previously (Before above mentioned new features were available) If you have multiple applications running inside an EC2(Although it's not recommended)and needed their own SSL certificates, it must point to multiple Load Balancers. If you have an Application Proxy AutoScaling Group which points to Backend Services with their own SSL. For the different path and port mappings for internal applications in EC2 (Similar to Point 1)

Yes, you can configure more than one load balancer with an autoscaling group -- why do you need more than one ELB for each ASG?
