1Y0-204 Exam Dumps : CCA-V Citrix Virtual Apps and Desktops 7 Administration exam

When using Machine Creation Services, the Delivery Controller must communicate with the configured hosting connection (such as VMware, Hyper-V, Citrix Hypervisor, Nutanix AHV). This communication enables provisioning, power management, and information retrieval from the hypervisor.

Citrix documentation defines the Citrix Host Service as the Delivery Controller service responsible for:

Managing hypervisor connections

Sending provisioning and power-action commands

Communicating with hosting infrastructure APIs

Initiating VM creation and updates for MCS catalogs

The Citrix Broker Service manages session brokering, not hypervisor communication.

The Citrix Environment Test Service focuses on diagnostics.

“Citrix Hypervisor Service” is not a Citrix Delivery Controller service.

Therefore, the correct service enabling Controller-to-hypervisor communication is the Citrix Host Service.

Machine Creation Services (MCS) is suitable for deploying a large number of virtual desktops with low impact on network infrastructure. MCS allows for user-installed applications and persistency by using differencing disks and personal vDisks.

The Virtual Delivery Agent (VDA) is a software component that enables machines to deliver applications and desktops to users. The VDA registers with a Delivery Controller and communicates session information to the Controller, which brokers connections between users and their resources. Users access their resources through Citrix Workspace app or a compatible web browser1
