1. If users served page1.htm from VM1, the user refreshes the web browser, page1.htm will be refreshed from VM1 always. Y/N No b/c session persistence is set to none. 2. If you change the protocol of rule 1, all web requests will fail.Y/N Yes - web requests use HTTP protocol, not TCP. 3. If you delete probe1.htm from VM2, LB1 will route all web requests to VM1. Y/N No - LB offers health probes w/ load-bal rules. Health probe config & probe responds deter which bkend pool instance will rcv new flows. Use health probes to detect app faliure on bkend instance. Create a custom response to a health probe & use health probe to control flow and manage load or planned downtime. When health probes fail, load bal stops sending new flows to unhealthy instance. https://docs.microsoft.com/en-us/azure/load-balancer/load-balancer-custom-probe-overview

if you delete the page1.html then health probe will fail, and then all requests will be sent to VM1, isnt this correct?

No Yes Yes The probe is used to determine if backend instance is ok. If the page is gone, lb will consider VM2 to be dead
