You need to dynamically scale resources for a pooled host pool based on the number of sessions per host. What should you create?

A scaling plan in Azure Virtual Desktop (AVD) is designed to automatically adjust the number of active session hosts in a pooled host pool based on predefined schedules and session thresholds. This allows for dynamic scaling, ensuring that resources are available when needed and deallocated when not, optimizing costs and performance. Incorrect options: A load balancer rule distributes incoming network traffic across multiple virtual machines but does not dynamically scale the number of active hosts. A virtual machine scale set allows you to deploy and manage a set of identical, auto-scaling virtual machines, but in AVD, scaling plans are the specific mechanism for session host management. While AVD host pools can leverage VMSS, the scaling logic for AVD sessions is handled by a scaling plan. An availability set ensures high availability by distributing VMs across different hardware in a datacenter but does not provide dynamic scaling capabilities.
