Correct Answer: B
The autoscale solution dynamically starts or stops existing session hosts, but doesn’t add or remove session hosts from the host pool. The autoscale solution automatically performs the following tasks: Schedules virtual machines to start and stop depending upon Peak and Off-Peak business hours.
Scales out VMs depending upon the number of sessions per CPU core.
Scales in VMs at the time of Off-Peak hours, allowing the minimum number of session host VMs running.
