It can monotor via the `Endpoint` or `CloudWatch`. For Health check endpoint , It pass only when then endpoint responds with the `2xx` and `3xx` status code. Also we need to allow ALB or other resources to grant the access for `Route 53` . Another thing we can also have `Parent Health check` to determine the overall health check status example If we have 3 health check for each resource and one `parent health check` then the `parent health check` will be passed when 2 of 2 health check is alive.
