VMware 2V0-51.23 Dumps - Pass VMware Horizon 8.x Professional Exam in 2026

To enable an instant-clone pool to use NVIDIA GRID vGPU, the administrator needs to do the following:

Install NVIDIA GRID vGPU in the physical ESXi hosts and select Shared Direct in the Host Graphics Settings12.

Prepare a golden image with NVIDIA GRID vGPU configured, including selecting the vGPU profile to use12.

Take a snapshot of the golden image12.

In Horizon Console, when creating an instant-clone pool, select Manage Using vSphere Client in the 3D Render field.Instant-clones inherit the settings configured in the vSphere Client for the golden image12.

Therefore, the possible reasons for the issue are:

The administrator has selected Shared instead of Shared Direct when editing the Host Graphics Settings for the ESXi host in the vCenter Server.This option is for vSGA, not vGPU3.

The golden image and snapshot that the administrator selected has not been configured for NVIDIA GRID vGPU.The administrator needs to verify that the correct vGPU profile is selected and that the NVIDIA drivers are installed in the golden image4.

The other options are not valid because:

Horizon 8 does have an explicit 3D renderer option for instant clone, but it is Manage Using vSphere Client, not NVIDIA GRID vGPU12.

Instant-clone pools do support NVIDIA GRID vGPU as long as the ESXi hosts and the golden image are properly configured12.

App Volumes is a real-time application delivery system that allows administrators to assign applications to users and groups in Horizon. App Volumes uses virtual disks called packages to store and deliver applications. When a user logs on to a desktop, the App Volumes agent attaches the assigned packages to the desktop and merges them with the OS disk. The user can then access the applications as if they were natively installed.

In this scenario, Adobe Acrobat 11 has been assigned to a user as an App Volumes package. When the user logs on to VM25, which already has Adobe Acrobat 11 natively installed, the App Volumes agent attaches the package to VM25 and creates a shortcut on the user desktop. However, the package does not overwrite or conflict with the natively installed application. Instead, when the user clicks on the shortcut, the App Volumes package for Adobe Acrobat 11 is opened and runs in an isolated environment. This allows the user to use different versions of the same application without affecting each other or the OS.Reference:App Volumes Architectureand [VMware Horizon 8.x Professional Course]

To create an instant-clone desktop pool, you must first create a golden image virtual machine and take a snapshot of it in a powered-down state. This snapshot provides the base image for the clones. You cannot create an instant-clone desktop pool from a VM template or a powered-on VM. Therefore, the administrator must take a snapshot of the VM that is the golden image before creating the new desktop pool.Reference:Create an Instant-Clone Desktop PoolandInstant Clone Desktop Pools

In a load balanced Horizon POD with three Connection Servers, there are 450 active Blast sessions connected. If one of these Connection Servers runs into an unplanned outage, only the active sessions from the failed Connection Server are disconnected, because HTTPS Secure Tunnel is disabled. This means that the other two Connection Servers can still handle the remaining sessions without interruption.

The HTTPS Secure Tunnel is a feature that allows Horizon Client devices to establish secure connections to virtual desktops and applications through the Connection Server. When this feature is enabled, all the display protocol traffic is tunneled through the Connection Server, which acts as a proxy between the client and the desktop.This increases the security and simplifies the network configuration, but also adds some overhead and dependency on the Connection Server availability1.

When this feature is disabled, the Horizon Client devices connect directly to the desktops using their IP addresses or hostnames, bypassing the Connection Server.This reduces the load and dependency on the Connection Server, but also requires more network configuration and firewall rules to allow direct access to the desktops2.

The Blast Secure Gateway is a similar feature that allows Horizon Client devices to establish secure connections to virtual desktops and applications using the Blast Extreme protocol through the Connection Server. When this feature is enabled, the Blast Extreme traffic is tunneled through the Connection Server, which acts as a gateway between the client and the desktop.When this feature is disabled, the Horizon Client devices connect directly to the desktops using Blast Extreme3.

In this scenario, both HTTPS Secure Tunnel and Blast Secure Gateway are disabled, which means that the Horizon Client devices connect directly to the desktops using Blast Extreme. Therefore, if one of the Connection Servers fails, only the sessions that were authenticated by that Connection Server are affected.The other sessions can continue without interruption, as long as they can reach their desktops directly4.

The other options are not correct for this scenario:

All 450 active sessions are disconnected, and have to re-connect again by the end-user. This would be true if HTTPS Secure Tunnel or Blast Secure Gateway were enabled, and all the display protocol traffic was tunneled through the Connection Server.In that case, any failure of a Connection Server would disconnect all the sessions that were using it as a proxy5.

All active sessions will stay connected, because HTTPS Secure Tunnel and Blast Secure Gateway are disabled. This would be true if there was no dependency on the Connection Server after authentication. However, even with HTTPS Secure Tunnel and Blast Secure Gateway disabled, there is still some communication between the Horizon Client and the Connection Server for session management and heartbeat monitoring. If a Connection Server fails, these communications are lost and the sessions are terminated.

All 450 active session are logged off immediately. This would be true if there was a global setting in Horizon Console to log off users when a Connection Server fails. However, there is no such setting in Horizon Console. The default behavior is to disconnect users when a Connection Server fails, not log them off.

On a VMware vCenter managed virtual machine, the VMware Horizon Agent knows which Connection Server it should register with during the Instant Clone pool creation process by querying VMware Tools for a Guestlnfo Variable during the cloning process. The Guestlnfo Variable is a custom property that is set on the parent virtual machine and contains the FQDN of the Connection Server. When the parent virtual machine is cloned, the Guestlnfo Variable is copied to the clone and read by the Horizon Agent.The Horizon Agent then registers with the Connection Server specified in the Guestlnfo Variable12.

The other options are not correct for this scenario:

Administrator provides this information in the ''Add Pool'' creation wizard. This option is not correct because the administrator does not need to provide the Connection Server information in the ''Add Pool'' creation wizard. The administrator only needs to select the vCenter Server, data center, cluster, resource pool, datastore, network, and snapshot of the parent virtual machine.The Connection Server information is already embedded in the parent virtual machine as a Guestlnfo Variable3.

Horizon Agent retrieves this information from an DNS SRV record. This option is not correct because the Horizon Agent does not use DNS SRV records to find the Connection Server during the Instant Clone pool creation process. DNS SRV records are used by Horizon Client devices to discover Connection Servers when they connect to a Horizon environment.DNS SRV records are optional and can be configured by the administrator to simplify client connections4.

Administrator provides this information in the Horizon Agent Installation Wizard on the master image. This option is not correct because the administrator does not need to provide the Connection Server information in the Horizon Agent Installation Wizard on the master image. The administrator only needs to select the features and options that are required for the desktop pool, such as VMware Horizon Instant Clone Agent, VMware Dynamic Environment Manager, VMware App Volumes, and so on.The Connection Server information is set on the master image after it is converted to a parent virtual machine by using a PowerShell script5.
