220-801 · Question #845
A customer wants to use a Microsoft virtual solution on an existing high-end graphics workstation. Which of the following is required to accomplish this task?
The correct answer is B. The motherboard BIOS must support virtual technology. Hardware virtualization requires the CPU and BIOS to support virtualization extensions (Intel VT-x or AMD-V), which must be enabled in the motherboard BIOS before a hypervisor can run.
Question
A customer wants to use a Microsoft virtual solution on an existing high-end graphics workstation. Which of the following is required to accomplish this task?
Options
- AThe motherboard must support PCI version 2.3 or above to use virtual technology.
- BThe motherboard BIOS must support virtual technology.
- CThe CPU L1 cache must have a minimum of 1 MB to support virtual technology.
- DThe chipset of the motherboard must have digitally signed drivers to work with virtual

Why each option
Hardware virtualization requires the CPU and BIOS to support virtualization extensions (Intel VT-x or AMD-V), which must be enabled in the motherboard BIOS before a hypervisor can run.
PCI version has no bearing on CPU or platform virtualization support - virtualization is a CPU and BIOS feature, not a bus interface standard.
The motherboard BIOS must have virtualization technology support (Intel VT-x or AMD-V) enabled to allow a hypervisor such as Hyper-V to run. Even if the CPU supports it, virtualization is disabled by default in many systems and must be toggled on in BIOS/UEFI settings. Without this BIOS-level enablement, the virtual machine software cannot access the hardware virtualization features.
There is no minimum L1 cache size requirement of 1 MB for virtualization - cache size does not determine virtualization capability.
Digitally signed drivers are a Windows driver signing requirement unrelated to enabling hardware virtualization technology on a motherboard.
