2V0-621 · Question #37
An administrator wants to reduce the memory overhead for a 3D graphics enabled virtual machine (VM). What advanced feature can be added to the VM configuration file to reduce memory overhead?
The correct answer is A. vga.vgaOnly=TRUE. Adding vga.vgaOnly=TRUE to a VM's configuration file disables SVGA 3D acceleration and reverts to basic VGA mode, reducing the memory overhead tied to 3D graphics rendering resources.

Why each option
Adding vga.vgaOnly=TRUE to a VM's configuration file disables SVGA 3D acceleration and reverts to basic VGA mode, reducing the memory overhead tied to 3D graphics rendering resources.
Setting vga.vgaOnly=TRUE in the VM's .vmx file instructs the VMware hypervisor to disable the SVGA device used for hardware-accelerated 3D graphics and fall back to standard VGA, which eliminates the additional framebuffer memory and GPU resource reservations that 3D-enabled VMs require.
vga.svgaEnable=FALSE is not a recognized VMware VM advanced configuration parameter and would have no effect on SVGA memory allocation.
svgaEnabled=FALSE does not follow the correct parameter naming convention used in VMware .vmx configuration files and would not be processed by the hypervisor.
svgaDisable=TRUE is not a valid VMware advanced configuration parameter and cannot be used to control SVGA device behavior or memory overhead.
