How does a load balancer determine if an instance is healthy?

Question

LB uses health checks to determine if an instance is healthy. It sends regular requests like HTTP to each instance. If the instance responds correctly, it's marked healthy. If it fails several times, it's marked unhealthy & the LB stops sending traffic to it.
