Citrix power management requires:
A hypervisor connection (Citrix Hypervisor, Hyper-V, VMware, Nutanix AHV)
Machines created or managed by Citrix Studio
The ability for Delivery Controllers to send power commands through the hypervisor API
Citrix documentation clearly states:
✔ Only virtual machines registered in a hosting connection support power actions such as:
✔ Virtual Desktop OS VDAs (typically Windows 10/11 or Windows 365-style desktops) support full power management because they run as virtual machines on the hypervisor.
Why the other options are incorrect:
Remote PC Access machines (A):Are physical desktops; power actions cannot be controlled via hypervisor APIs.
Virtual Server OS machines (B):Although virtual, they are normally used as multi-session hosts; Citrix power management is not intended for them in standard deployments.
Physical Server OS machines (D):Physical hardware is not managed through hosting connections, so no power control is possible.
Thus, Virtual Desktop OS machines are the correct answer.
