You created a load balancer to distribute HTTPS traffic between two VMs (VM1 and VM2). Which two additional load balancer resources must you create before you can create the load balancing rule?

A backend pool is essential because it defines the group of virtual machines (VM1 and VM2 in this scenario) that will receive the load-balanced traffic. Without a backend pool, the load balancer wouldn't know where to direct the incoming requests. A health probe is also crucial as it monitors the availability and health of the instances within the backend pool. This ensures that traffic is only sent to healthy VMs, preventing requests from being routed to unresponsive servers. An inbound NAT rule is used for direct port forwarding to a specific VM, not for load balancing across multiple VMs. A virtual network is a prerequisite for creating VMs and the load balancer itself, but it's not a direct load balancer resource that needs to be created before the rule. A frontend IP address is also necessary for the load balancer to receive traffic, but it's typically configured as part of the load balancer creation process, often before defining the specific rules.
