A technician is creating a Windows 11 virtual machine on a laptop and assigns the guest only 1 GB of RAM and a single vCPU, even though the OS manufacturer recommends 4 GB of RAM and two cores. Which of the following outcomes is the MOST likely when the user begins running typical office applications in the VM?
The hypervisor will automatically expand the VM's CPU and memory, so performance will remain normal.
Applications inside the VM will respond slowly, and the guest may experience frequent swapping or high CPU wait times.
The VM will run faster because smaller resource allocations improve cache efficiency.
The host will overheat and draw more power because the VM's light footprint drives the CPU to maximum use.
Because the virtual machine has been given less memory and CPU time than the guest operating system and its applications require, the guest will have to swap memory to disk and wait for CPU scheduling, resulting in noticeably sluggish performance. Hypervisors do not automatically grant unlimited extra resources, and smaller allocations do not make the VM faster. Over-provisioning, in contrast, can waste host resources or slow down other VMs.
