The correct answer is A. Assign 1 virtual CPU to the Guest. Guest VMs in a virtualized environment use virtual CPUs (vCPUs) that the hypervisor maps to physical CPU cores. The correct action is to assign a vCPU to the guest VM, not to allocate physical CPU resources directly.
Question
An administrator is responsible for managing a host that is part of a private cloud. The host has one physical quad core CPU. The administrator is tasked with creating a new guest that requires a single CPU. Which of the following actions should the administrator do?
Options
- AAssign 1 virtual CPU to the Guest
- BAssign 1 virtual CPU to the Host
- CAssign 1 physical CPU to the Guest
- DAssign 1 physical CPU to the Host

Why each option
Guest VMs in a virtualized environment use virtual CPUs (vCPUs) that the hypervisor maps to physical CPU cores. The correct action is to assign a vCPU to the guest VM, not to allocate physical CPU resources directly.
Virtual CPUs (vCPUs) are the abstracted compute resources that hypervisors such as VMware ESXi or Microsoft Hyper-V present to guest VMs. Assigning 1 vCPU to the guest allows the hypervisor to schedule that virtual processor against the available quad-core physical CPU, satisfying the guest requirement. This is the standard method for allocating CPU resources to guests without exposing raw physical hardware.
The host is the physical machine running the hypervisor - vCPUs are assigned to guest VMs, not back to the host itself.
Guests in a virtualized environment cannot be directly assigned physical CPUs; the hypervisor abstracts physical cores and presents them as vCPUs to guests.
Physical CPUs are hardware that belongs to the host by definition and are not a configurable assignment target for the host.
