A desktop technician is configuring a host workstation to run 3 concurrent guest virtual machines (VMs) for software testing using client-side virtualization. Each guest VM requires a minimum of $4\text{ GB}$ of RAM. The host operating system requires $4\text{ GB}$ of RAM to maintain stable performance without relying on virtual memory paging. What is the minimum amount of physical RAM that must be installed in the host workstation to support this configuration?

A
$12\text{ GB}$
$16\text{ GB}$ Cevap
C
$8\text{ GB}$
D
$24\text{ GB}$

Cevap

16\text{ GB}

of physical RAM is the minimum requirement.

To determine total physical host RAM required, sum the memory requirements of all concurrent guest virtual machines (

3 \times 4\text{ GB} = 12\text{ GB}

) and add the host operating system overhead requirement (

4\text{ GB}

), resulting in a minimum total of

16\text{ GB}

Adım Adım Çözüm

Calculate total memory required for all guest virtual machines

3 \text{ VMs} \times 4\text{ GB/VM} = 12\text{ GB}

Each guest VM requires dedicated RAM allocated for its guest operating system and application workload.

Add host operating system RAM overhead

12\text{ GB (guests)} + 4\text{ GB (host OS)} = 16\text{ GB}

The hypervisor host OS requires dedicated physical RAM to avoid memory overcommitment and disk thrashing.
