To ensure that session hosts in Pool1 are automatically scaled based on demand, which resource requires configuration?

To enable automatic scaling of session hosts in a specific pool, such as Pool1, it is essential to configure the settings associated with that pool. Pool configuration includes specifying scaling rules and policies that define how and when session hosts are added or removed based on user demand. This ensures that the resources are efficiently utilized and can accommodate fluctuations in user activity.

The scaling configuration can adjust the number of active session hosts in Pool1 depending on the workload, thus optimizing costs and performance. Properly setting up the pool means that administrators can manage the session hosts collectively, responding dynamically to the needs of users without having to handle each individual host separately.

While other options may reference specific hosts or resource groups, they do not encapsulate the overall demand management capability that is inherently tied to the configuration of the pool itself.
