  Which two could be the cause of the issue? (Choose two.)

  A. The customization specification has been renamed or deleted.

  B. Desktops can only be customized after the end user logs into the virtual machine.

  C. The compute account of the template has been removed from the Active Directory.

  D. The administrator does not have sufficient permissions to access the customization specification.

• Question 22:

  A Horizon administrator has been running Application Profiler to preserve application-specific user defined settings. These files have grown to 2.3GB in size for a particular user and have negatively impacted the user experience. What can be done to the configuration to improve the user experience?

  A. Configure exclusions to filter out unnecessary registry entries.

  B. Configure exclusions to filter out unnecessary folders.

  C. Use Deepest Registry Path.

  D. Change the default save path.

  Correct Answer: B

  https://blogs.vmware.com/euc/2017/04/vmware-user-environment-manager-application-profiler-exclusions-part-3.html Changing the save path will not do anything to reduce the size of the profile that is causing the performance issues. However, excluding unnecessary folders such and "temp files" in the profile configuration will have an effect on the size of user profiles and can help performance.

• Question 23:

  An end-user is experiencing a black screen when connecting to their virtual desktop. After a few seconds, the connection closes. Which could be the cause of the issue? (Choose three.)

  A. The Client machine video memory is too high.

  B. There is a vRAM shortage on the Horizon virtual machine.

  C. The Horizon Virtual Machine video memory is too high.

  D. There is an incorrect firewall configuration.

  E. The incorrect video driver version is installed on the Horizon virtual machine.

• Question 24:

  An administrator configured a virtual machine to use an NVIDIA card but the virtual machine is not starting up. What could be the cause of the issue? (Choose two.)

  A. No suitable host could be found.

  B. Not all memory has been reserved on the VM.

  C. Not all CPU has been reserved on the VM.

  D. The Desktop Pool doesn't support 3D cards.

  E. 3D graphics cannot be used with local storage.

  Correct Answer: AB

  Reference: https://techzone.vmware.com/resource/deploying-hardware-accelerated-graphics-vmware-horizon-7#horizon-pool-and-farm-settings

  If you configure a graphics card, and the host has no resources available (all GPU memory used for example) or not all guest memory has been reserved, then the VM won't start. By process of elimination: Not all CPU has been reserved on the VM -> CPU reservation not necessary The Desktop Pool doesn't support 3D cards -> There is no mention of Horizon within this question. 3D Graphics cannot be used with local storage -> 3D Graphics is not dependant on storage.

• Question 25:

  Refer to the exhibit.

  

  An administrator schedules the push of a new image to desktop pool and receives the exhibit. Where should the administrator first look for the cause of the issue?

• Question 26:

  Refer to the exhibit.

  

  When editing an existing instant-clone pool, an administrator cannot find the option to configure the vRAM size in the wizard.

  Referencing the exhibit, which could be the cause of the issue?

  A. Increasing vRAM size is only possible for manual pools.

  B. Modifying the vRAM settings is not permitted when selecting VMware Blast as default protocol.

  C. Modifying the vRAM settings is not permitted when selecting Manage using vSphere Client.

  D. Configuring vRAM size is only permitted during pool creation.

  Correct Answer: C

  The VRAM settings that you configure in Horizon Console take precedence over the VRAM settings that can be configured for the virtual machines in vSphere Client or the vSphere Web Client, unless you select the Manage using vSphere Client option. https://docs.vmware.com/en/VMware-Horizon/2209/virtual-desktops/GUID-8C0A6D6E-DCE0-461D-B0BE-EF226B04F642.html Manage using vSphere Client. Select this setting for all non-vGPU options. The 3D Renderer option that is set in vSphere Web Client (or vSphere Client in vSphere 5.1 or later) for a virtual machine determines the type of 3D graphics rendering that takes place. Horizon 7 does not control 3D rendering. In the vSphere Web Client, you can configure the Automatic, Software, or Hardware options. These options have the same effect as they do when you set them in Horizon Administrator. Use this setting when configuring vDGA and AMD Multiuser GPU Using vDGA. This setting is also an option for vSGA. When you select the Manage using vSphere Client option, the Configure VRAM for 3D Guests, Max number of monitors, and Max resolution of any one monitor settings are inactive in Horizon Administrator. You can configure the amount of memory in vSphere Web Client.
