A technician must run two guest operating systems simultaneously on a laptop along with the host OS. The CPU already supports virtualization extensions, and the laptop contains a fast NVMe SSD. Which of the following hardware upgrades will have the MOST immediate impact on maintaining smooth performance for all operating systems running at the same time?
Upgrade the Wi-Fi adapter to a Wi-Fi 6 (802.11ax) card
Each virtual machine reserves a block of the host's physical RAM. When the total assigned memory exceeds what is physically available, the host begins paging to disk, drastically slowing every OS. Installing additional system RAM prevents this bottleneck and lets multiple VMs run concurrently without heavy swapping. Faster storage, a newer network adapter, or a dedicated GPU can improve specific tasks, but they do not relieve the fundamental memory pressure created by additional virtual machines.
