   A technician needs to increase the available RAM on a virtual workstation. Which of the following should the technician do?

   • AIncrease the ECC memory timings in the BIOS.
   • BUpgrade to the latest DDR5 modules.
   • CClear the temporary files on the workstation's boot drive.
   • DUse a hypervisor to adjust the resource allocation.

   Show answer

   Answer: D

   Explanation

   A hypervisor is a software layer that enables virtualization and allows multiple virtual machines to run on a single physical machine. With a hypervisor, the technician can modify the resource allocation, including the amount of RAM assigned to the virtual workstation. By adjusting the resource allocation through the hypervisor, the technician can increase the amount of RAM available to the virtual workstation, allowing it to run more efficiently and handle larger workloads. Option D. Use a hypervisor to adjust the resource allocation is the correct answer in this scenario.

The key clues are that multiple peripherals connected through the USB-C hub have stopped working, even after restarts and alternate devices tested. This points to a power delivery or bandwidth issue with the hub itself.
