You deployed Azure Application Gateway and didn't configure a health probe. How is health of backend pools monitored?
Experience Level: Junior

Answer
An application gateway automatically configures a default health probe when you don't set up any custom probe configuration. The monitoring behavior works by making an HTTP GET request to the IP addresses or FQDN configured in the backend pool. For default probes if the backend http settings are configured for HTTPS, the probe uses HTTPS to test health of the backend servers.
