In Citrix Virtual Apps and Desktops 2402 LTSR, the printing subsystem supports dynamic printer enumeration, which allows Citrix to automatically detect changes to client-side printers while an HDX session is running. This functionality is part of the Citrix Printing Virtual Channel.

When a user:

Adds a printer on their endpoint

Removes a printer on their endpoint

Citrix automatically updates the list of auto-created printers within the active session. The user does not need to log off, refresh, or perform any manual action. The VDA receives updated information from the Workspace app (or Receiver), and the in-session printer list adjusts accordingly.

Why the other choices are incorrect:

A: The session is affected; the printer list updates dynamically.

B: User intervention is not required.

D: Citrix does adjust the in-session printer list — dynamic support is built into the printing subsystem.

Application Lingering allows applications to stay open for a configurable amount of time after a user closes them, which can reduce application launch times in subsequent sessions.

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.

Citrix Host Service Description within Hosting Connections

According to the Citrix documentation, when you bind an interface to a VLAN, the native VLAN of the interface changes to the VLAN to which it is bound. In this scenario, the native VLAN of interface 1/1 was 40 before the command was executed, so it remains 40 after the command is executed. The command does not change the native VLAN of the interface, only the VLAN to which it is bound. Therefore, the correct answer is B.

 Citrix Director is the tool designed for monitoring the overall daily performance of a Citrix Virtual Apps and Desktops Site. It provides administrators with insights into the environment’s operations, allowing for proactive management and troubleshooting

Citrix Studio provides a feature called Limit Visibility, which allows administrators to hide specific published resources (apps or desktops) from chosen users or groups. This is the correct method to selectively exclude users from seeing or launching certain apps without removing them from the Delivery Group.

Correct Approach:

To prevent HR10 from seeing or accessing APP_A, the administrator should configure Limit Visibility so that only HR1–HR9 are allowed visibility for APP_A.

This ensures:

The entire HR group still receives all published apps

Only HR10 is restricted from APP_A

The Delivery Group configuration remains intact

Why the other options are incorrect:

A. Remove HR10 from the Delivery Group:This would remove HR10’s access to all Delivery Group applications, not just APP_A.

C. Remove APP_A from the Delivery Group:This removes the app for everyone, not just HR10.

D. Limit visibility on APP_A to HR10:This would assign visibility only to HR10, the opposite of what is needed.

Citrix App Assignment Best Practices

The Group Policy Object administrative template, which includes the ADMX and ADML files, is recommended for configuring Citrix Workspace app settings at the domain level. This allows the settings to be applied across various user devices within the enterprise

 The Citrix Universal Print Server provides universal printing support for network printers. The Universal Print Server uses the Universal print driver, a single driver on the Multi-session OS machine that allows local or network printing from any device, including thin clients and tablets. This feature can help reduce the number of Windows drivers on the VDA machines by using a single driver for all network printers

 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.

 According to the Citrix Virtual Apps and Desktops 7 Deployment and Administration course, page 14 of Module 1: Architecture Overview, “Layer 3 mode is the default mode of operation for a Citrix ADC appliance. In this mode, the appliance acts as a router and routes packets based on the destination IP address.” Therefore, if the Citrix ADC receives packets that are destined for a MAC address owned by the Citrix ADC, but the destination IP address does not belong to the Citrix ADC, it will route the packets based on the destination IP address.
