An administrator is attempting to use Hyper-V on a server with an AMD processor but is receiving an error. Which of the following should be enabled to resolve the error?

XD (Execute Disable Bit) is Intel's implementation of Data Execution Prevention (DEP); for an AMD processor, the equivalent technology is called NX.

Hyper-V requires both hardware-assisted virtualization (AMD-V for AMD processors) and hardware-enforced Data Execution Prevention (DEP) to be enabled. For AMD processors, DEP is referred to as NX (No-Execute) in the BIOS/UEFI settings, and it must be enabled for Hyper-V to function correctly.

VT (Virtualization Technology) is the generic term for hardware-assisted virtualization (like AMD-V or Intel VT-x), which is also a required feature for Hyper-V, but NX (DEP) is another distinct and essential requirement that is often disabled by default.

Hyperthreading is a CPU technology that allows a single physical core to execute multiple threads concurrently to improve performance, but it is not a requirement for Hyper-V to function.
