Which of the following computers would be MOST suitable to host virtual workstations?

512 MB of RAM is wholly insufficient for hosting virtual workstations, as a single modern guest OS alone typically requires 1-4 GB minimum, making multiple VMs impossible.

Like option A, 512 MB RAM makes this system incapable of hosting any meaningful virtual workstation; the slower spinning hard drive compounds the performance deficiency.

RAM is the most critical bottleneck for virtualization hosts because each virtual machine requires its own memory allocation; 64 GB provides sufficient headroom for multiple concurrent guest workstations. The 1 TB SSD reduces storage I/O latency significantly compared to a spinning hard drive, improving VM responsiveness and snapshot performance. The Gigabit NIC ensures adequate network throughput for multiple VMs sharing the physical interface simultaneously.

While this option has the required 64 GB RAM and SSD, a Fast Ethernet NIC (100 Mbps) creates a network bottleneck when multiple VMs share the physical adapter, making Gigabit the preferred choice.
