VMware 2V0-51.23 Exam - Topic 3 Question 36 Discussion

Actual exam question for VMware's 2V0-51.23 exam
Question #: 36
Topic #: 3
[All 2V0-51.23 Questions]

An administrator has added a supported PCI graphics accelerator to a virtual machine configuration. When the administrator tries to power on the virtual machine, an error is displayed and the virtual machine remains powered off.

Which of the following virtual machine configuration settings needs to be applied to enable the virtual machine to power on?

Show Suggested Answer Hide Answer
Suggested Answer: B

To enable a virtual machine to power on with a PCI graphics accelerator, such as a GPU, attached to it, the administrator needs to reserve all guest memory for that virtual machine. This is because PCI devices require direct memory access (DMA) to function properly, and memory overcommitment can interfere with DMA operations.Reserving all guest memory ensures that no memory swapping or ballooning occurs on the virtual machine, and that the memory address space is contiguous and available for DMA56.

The other options are not required or valid because:

Enabling Video Card 3D Graphics is not necessary for using a PCI graphics accelerator.This option is for using software-accelerated graphics or virtual shared graphics acceleration (vSGA) on a virtual machine7.

Setting Memory Shares to High does not guarantee that all guest memory will be reserved. Memory shares only affect how memory resources are distributed among competing virtual machines when there is memory contention on the host. Memory shares do not prevent memory overcommitment or swapping.

Disabling CPU Hot Plug does not affect the use of a PCI graphics accelerator. CPU Hot Plug allows adding or removing virtual CPUs from a powered-on virtual machine. It has no relation to PCI devices or DMA operations.

Wait, can a PCI GPU even work in a VM? Sounds sketchy.

I recall that memory shares usually don't affect power states directly, so I doubt option C is correct.

I'm feeling pretty confident about this one. Based on the information provided, the answer is most likely "Enable Video Card 3D Graphics." That seems like the setting that would need to be applied to address the issue with the PCI graphics accelerator.

Okay, let's see here. The virtual machine isn't powering on, and the issue is related to the PCI graphics accelerator. I'm guessing the answer has to do with enabling or configuring the graphics settings for the virtual machine. I'll try to eliminate the options that don't seem relevant.

Hmm, I'm a bit unsure about this one. The question mentions a PCI graphics accelerator, so I'm wondering if the answer might have something to do with graphics settings. I'll need to think this through carefully.

This seems like a straightforward question about virtual machine configuration settings. I'll carefully read through the options and think about which one is most likely to address the issue of the virtual machine not powering on due to the PCI graphics accelerator.
