The amount of ______ power and memory are the main factors limiting the number of VMs that a host can support.

Explanation:
The key idea is that virtual machines compete for the host’s CPU and RAM. Each VM needs a portion of processing power to run its operating system and applications and a chunk of memory to hold its runtime data. The hypervisor must schedule CPU time across all VMs and allocate memory to them; when those resources run out, you can’t safely start more VMs or performance will collapse. Bandwidth, storage, and graphics can affect performance in different ways, but they don’t usually cap the number of VMs as directly as CPU and memory do.
