Correct Answer: B, DThere are two potential causes for the NVIDIA GRID vGPU option not being available in the 3D Render field when creating an instant-clone pool in Horizon Console. First, it is possible that the golden image and snapshot chosen by the administrator do not have NVIDIA GRID vGPU configured correctly. Instant clones inherit the settings configured in the vSphere Client, so if the golden image is not set up with NVIDIA GRID, the option will not appear. Second, to enable NVIDIA GRID vGPU, the Host Graphics Settings for the ESXi host must be set to Shared Direct. If the administrator has selected Shared instead, it may prevent the vGPU option from appearing. Therefore, both incorrect configuration of the golden image and incorrect host settings can cause the issue.
