Final answer:
It is true that individual EC2 instances do not need to be registered with the load balancer when using Elastic Load Balancing with an Auto Scaling group, as this process is handled automatically.
Step-by-step explanation:
The statement that when using Elastic Load Balancing with an Auto Scaling group, it is not necessary to register individual EC2 instances with the load balancer is true. When an Auto Scaling group is used in conjunction with an Elastic Load Balancer, the instances launched by the Auto Scaling group are automatically registered with the load balancer. As the group scales out (adds instances) or scales in (removes instances), the Elastic Load Balancing service automatically updates the pool of instances it directs traffic to.
This integration simplifies the management of traffic distribution among the multiple instances in your application and ensures that only healthy instances receive traffic by performing health checks on the instances.
