   A company runs a web application on a group of virtual machines behind a load balancer. The application has a health check endpoint at /health.

   • AUse a load balancer with a health check and configure it to automatically provision a new VM when an instance fails.
   • BUse an auto-scaling group with a health check that references the /health endpoint and a load balancer that performs the same health check.
   • CUse a cron job that runs every minute to check the /health endpoint and manually terminate unhealthy VMs.
   • DUse a monitoring service that sends an alert when the /health endpoint fails, and have an operator manually replace the VM.
