Which option allows you to configure the number of session hosts in Azure Virtual Desktop?

The correct choice is to configure the number of session hosts in Azure Virtual Desktop through Host Pool settings.

Host Pools in Azure Virtual Desktop are a collection of session hosts that provide a virtual desktop or application experience to users. When setting up or managing a host pool, you have the ability to define how many session hosts are included. This is crucial for scaling your deployment to meet user demand, as it influences the overall performance and availability of resources.

By managing the host pool settings, you can easily adjust the number of session hosts based on user load, ensuring that sufficient resources are available for the required number of concurrent users. This flexibility allows administrators to respond effectively to changes in user requirements and optimize resource utilization.

Other options, such as Management Groups, Azure Active Directory roles, and Azure Policy settings, serve different purposes and do not directly relate to the configuration of session hosts in an Azure Virtual Desktop environment. Management Groups are used for organizing resources across subscriptions, Azure Active Directory roles are related to identity and access management, and Azure Policy settings enforce compliance and governance rather than directly managing session hosts.
