Question 1Choose one

An administrator is troubleshooting poor user experience for a group of graphic designers using 3D modeling software in their Horizon desktops. The goal is to provide dedicated GPU resources to each designer's virtual machine for maximum performance. Which graphics acceleration technology and configuration should be implemented? graph TD subgraph ESXi_Host GPU1[Physical NVIDIA GPU 1] GPU2[Physical NVIDIA GPU 2] end subgraph Virtual_Machines VM1[Designer VM 1] VM2[Designer VM 2] end GPU1 -- Passthrough --> VM1 GPU2 -- Passthrough --> VM2

Question 2Choose one

After a recent network change, users connecting externally through a Unified Access Gateway (UAG) report that they can authenticate successfully, see their list of available desktops, but receive a black screen when they try to launch a session. Internal users connecting directly to the Connection Server are unaffected. What is the most likely cause of this issue?

Question 3Choose 3

A Horizon administrator needs to create a custom role for a help desk team. The team must be able to log off user sessions and send messages to users, restart virtual desktops, and look up users and sessions in the Horizon Help Desk Tool. They must NOT be able to create or delete pools, or modify global configuration settings. Which THREE privileges should be assigned to this custom role? (Select THREE)

Question 4Choose one

A global organization has two separate Horizon pods, one in New York and one in London. They want to implement a solution that allows users to connect to a single global namespace (e.g., `desktops.company.com`) and be directed to their entitled desktop in their home site. The solution must also provide site affinity and failover capabilities if one site becomes unavailable. Which Horizon feature should be implemented to meet these requirements?

Question 5Choose one

In the context of Horizon architecture, which component is primarily responsible for authenticating users, brokering connections to desktops and applications, and managing the VDI environment?

Question 6Choose one

A user needs to access their Horizon virtual desktop from a kiosk computer where they cannot install any software. Which Horizon client should they use?

Question 7Choose one

True or False: A single Horizon pod can span multiple physical datacenters.

Question 8Choose one

When would an administrator choose to implement Virtual Shared Graphics Acceleration (vSGA) instead of NVIDIA GRID vGPU for a desktop pool?

Question 9Choose one

An architect is designing a Horizon environment that will use instant clones. To reduce the impact of I/O storms, they plan to store the replica VMs on a separate SSD-backed datastore and the instant clones on HDD-backed datastores. Which requirement applies to this configuration?

Question 10Choose one

Where in the Horizon Console would an administrator go to create a new farm of RDSH servers that will be used to publish applications?

Question 11Choose one

In App Volumes, what is the function of a Writable Volume?

Question 12Choose one

After upgrading the Horizon Agent in the golden image for a large instant-clone pool, an administrator takes a new snapshot and runs a push-image operation. The image publishes successfully (the internal template and replica VMs are created), but many of the new desktop clones are stuck in a "Customizing" state and eventually error out. Existing users' old clones are still in use while the push image is rolling. What is a common cause for instant clones getting stuck in the customization phase in this scenario?
