Difficulty: MediumVirtual Machine Resource Requirements and Hardware Support

A technician is configuring a host workstation to run virtual machines (VMs) for software compatibility testing across multiple operating systems. Upon attempting to launch a 64-bit guest OS within the client-side hypervisor, an error indicates that hardware-assisted virtualization and memory virtualization features are disabled. Which of the following features must be enabled in the motherboard's UEFI/BIOS setup to satisfy these requirements? (Select TWO.)

  1. Intel VT-x or AMD-V (Hardware-assisted virtualization)Answer
  2. Second Level Address Translation (SLAT / EPT / NPT)Answer
  3. C
    Hyper-Threading / Simultaneous Multithreading (SMT)
  4. D
    Trusted Platform Module (TPM 2.0)

Answer

The technician must enable Hardware-assisted virtualization (Intel VT-x or AMD-V) and Second Level Address Translation (SLAT / EPT / NPT) in the host system's UEFI/BIOS settings.
Enabling Intel VT-x or AMD-V grants the hypervisor direct access to CPU hardware extensions required to execute guest operating systems efficiently. Enabling Second Level Address Translation (SLAT) provides hardware-based memory translation (Extended Page Tables or Nested Page Tables), significantly reducing memory management overhead for guest virtual machines.

Step-by-Step Solution

1
Determine the CPU requirement for running 64-bit guest operating systems in a hypervisor.
Identify that hardware-assisted virtualization (Intel VT-x or AMD-V) must be enabled in host UEFI/BIOS.
Hypervisors depend on direct hardware virtualization instruction extensions on the CPU to isolate and execute guest OS code.
2
Determine the hardware feature responsible for managing virtual machine memory page tables.
Identify Second Level Address Translation (SLAT / EPT / NPT) as the memory hardware feature.
SLAT offloads virtual-to-physical memory mapping from hypervisor software directly to the memory controller hardware.
