   You have an internal load balancer with a backend pool of two VMs running a web application. The health probe is configured as HTTP on port 80 with a request path of /health. The application's /health endpoint returns a 500 status code when the application is overloaded. You notice that the load balancer marks both VMs unhealthy during peak hours, causing an outage. What should you do to prevent this?

   • AChange the /health endpoint to return 200 even when overloaded
   • BRemove the health probe entirely
   • CIncrease the probe interval and unhealthy threshold to tolerate temporary 500 responses
   • DChange the health probe to TCP on port 80
