A customer needs to run several virtual machines on their design workstation to work on cross platform software. Which of the following should be maximized to improve workstation performance?…
The correct answer is B. RAM C. Number of CPU cores. Running multiple VMs simultaneously is most constrained by available RAM and CPU cores, as each VM requires dedicated allocations of both resources.

Why each option
Running multiple VMs simultaneously is most constrained by available RAM and CPU cores, as each VM requires dedicated allocations of both resources.
Cooling fans regulate thermal output but do not increase compute resources available to virtual machines.
Each virtual machine requires its own dedicated RAM allocation; insufficient RAM forces the hypervisor to use disk-based swap, severely degrading performance across all VMs.
Each VM can be assigned one or more CPU cores; more physical cores allow the hypervisor to schedule VM workloads in parallel rather than time-slicing, directly improving multi-VM throughput.
Additional storage space increases capacity but does not significantly improve VM execution speed unless the bottleneck is disk I/O.
PCIe slots allow adding expansion cards but adding slots alone does not improve hypervisor scheduling of RAM or CPU for VMs.
