The Citrix Virtual Apps and Desktops architecture is divided into multiple conceptual layers. In Citrix architectural documentation, the Resource Layer is the layer responsible for the hosting infrastructure, which consists of:

Hypervisors (Citrix Hypervisor/XenServer, Hyper-V, VMware, Nutanix AHV)

Virtual machines

Machine creation technologies (MCS/PVS)

This layer provides the actual compute, storage, and virtualization capabilities required to run VDAs. Since the hypervisor platform is part of the virtual machine hosting environment, it resides in the Resource Layer.

The Hardware Layer refers only to physical server components.

The Control Layer manages brokering, delivery, and site configuration.

The Access Layer involves authentication and user connection entry points such as StoreFront and Citrix Gateway.

Therefore, because the hypervisor is part of the virtualization hosting environment, it belongs specifically to the Resource Layer.

 According to the Citrix documentation1, persistence time-out is the parameter that determines how long the service continues to serve requests from the client after it is disabled manually. The service accepts new requests or connections only to honor persistence. After the persistence time-out expires, no new requests or connections are directed to the service and all of the existing connections are closed. This parameter is available only when the service is disabled gracefully. The default value is 2 minutes. The other options are not related to the scenario described in the question.
