An administrator is attempting to install a 64-bit OS on a VM that is hosted by a server known to have 64- bit CPUs. However, the new VM will not boot properly. Which of the following is MOST likely the problem?

Question

Accepted Answer

C. The server does not have AMD-V or Intel VT switched on. AMD-V (AMD) and Intel VT-x (Intel) are CPU-level hardware virtualization extensions that must be explicitly enabled in the system BIOS/UEFI before a hypervisor can expose a 64-bit environment to guest VMs. Without these extensions enabled, the hypervisor lacks the hardware support needed to translate and execute 64-bit privileged instructions for the guest OS, causing the VM to fail to boot. Simply having a 64-bit CPU is insufficient - the feature must be toggled on in firmware settings.

Answer

A. The server is not a Type 1 hypervisor. Whether the hypervisor is Type 1 (bare-metal) or Type 2 (hosted) does not determine 64-bit guest OS support; both types can run 64-bit VMs if CPU virtualization extensions are enabled.

Answer

B. The server is not a Type 2 hypervisor. Type 2 hypervisor classification is irrelevant to this failure; a Type 2 hypervisor can still run 64-bit guests when the underlying CPU has virtualization extensions enabled in BIOS/UEFI.

Answer

D. The server does not have hybrid server capability turned on. Hybrid server capability is not a real or recognized hardware or firmware feature related to running 64-bit VMs, making this option technically invalid.
