In a private cloud, the host has one physical quad-core CPU. The administrator needs to create a guest that requires a single CPU. What action should be taken?

In a private cloud, the host has one physical quad-core CPU. The administrator needs to create a guest that requires a single CPU. What action should be taken?

• A. Assign 1 virtual CPU to the Guest
• B. Assign 1 virtual CPU to the Host
• C. Assign 1 physical CPU to the Guest
• D. Assign 1 physical CPU to the Host

Answer: (A)

In virtualization, CPU resources are exposed to the guest as virtual CPUs (vCPUs) and are scheduled onto the host’s physical cores by the hypervisor. To meet a requirement of a single CPU for the guest, you assign one vCPU to the virtual machine. The hypervisor will run that vCPU on one of the host’s four physical cores, while the host keeps control of the remaining cores. You don’t assign a physical CPU directly to a guest, and you wouldn’t allocate a vCPU to the host for the guest’s use. Starting with one vCPU gives the guest the requested processing capability, and you can adjust later if more performance is needed.
