A Windows IO VM fails to power on With an NVIDIA vCPU profile in ESXi 7. The VM is configured with NVIDIA profile by selecting Shared PCl Device, adding the NVIDIA GRID vCPU device. and selecting the Profile under VM settings.
The following error message is displayed in the vSphere web client:



What should be done to resolve this issue?

  1. Change the Graphics mode of the host from Shared to Shared Direct
  2. Change the Graphics mode of the host from Shared to Shared Direct
  3. Switch the GPU mode to graphics mode using gpumodeswitch command.
  4. change the Graphics mode of the host from Shared Direct to Shared.
  5. Switch the GPU mode to compute mode using gpumodeswitch command.

Answer(s): C

Explanation:

gpumodeswitch is a command-line tool that is used to switch supported NVIDIA GPUs between compute and graphics mode. Compute mode allows multiple VMs to share a GPU for CUDA workloads. Graphics mode allows a single VM to use a GPU for graphics workloads12.



An administrator supports a user group that spans across 10 Nutanix clusters for a medium-sized medical communications firm. The 10 Nutanix clusters are managed by a single Prism Central instance.
This group's virtual desktops are all cloned from a common gold image and all applications are published from a Citrix Virtual Apps farm. The administrator needs to keep the gold image in sync across all of the clusters.
What is the best way to achieve this?

  1. use the native replication facility within the Machine Catalog
  2. Setup a Protection Domain with the gold image as 3 protected entity.
  3. Upload the gold image to Prism Central Image Service.
  4. use Move to maintain all gold images across the clusters.

Answer(s): C

Explanation:

Prism Central Image Service allows you to upload and manage images through Prism Central by using the v3 API. You can also choose where your images will be available across different clusters123

An administrator has been evaluating a performance issue with the current Citrix VD' solution on

Nutanix. During the evaluation, the administrator finds out there is a feature that is enabled called Shadow Clones.
What would happen if an administrator disabled Shadow Clones within a company's VDI environment?

  1. Deployment times would increase as the number deployed desktops increase,
  2. Deployment times would decrease when deploying additional desktops.
  3. Boot storms would be eliminated due to desktop resource contention.
  4. Boot storms would be eliminated because the number of desktops would be throttled.

Answer(s): A

Explanation:

Nutanix's Shadow Clones feature is used to create linked clones or snapshots of base VMs, which can improve VM provisioning time and storage efficiency by reducing the amount of duplicated data. If an administrator disables Shadow Clones within a company's VDI environment, it is likely that deployment times would increase as the number of deployed desktops increases. This is because linked clones or snapshots would no longer be used, so each new desktop deployment would require creating a full copy of the base VM.
Nutanix Shadow Clones allow for distributed caching of a particular disk or VM data, which are in a `multi-reader' scenario. This can help in scenarios such as VDI or private clone boot storms, where VMs on multiple nodes read from the same set of base disks12



In a VMware Horizon environment running on Nutanix, an administrator has noticed that create, start, shut down, and delete operations are taking longer than expected, the environment is currently configured with one vCenter instance and has 10,000 virtual desktops.
What is the recommended number of vCenter instances in this configuration?

  1. 1
  2. 2
  3. 5
  4. 10

Answer(s): B

Explanation:

vCenter can execute approximately 640 concurrent operations before incoming requests are queued, and can support up to 2,000 concurrent sessions. VMware Horizon 8 can support up to 120,000 active sessions in a Cloud Pod Architecture pod federation23. Therefore, if the environment has 10,000 virtual desktops, one vCenter instance might not be enough to handle all the operations and sessions efficiently. The recommended number of vCenter instances in this configuration is B (2).
