A desktop technician is assembling a workstation that will run four concurrent guest virtual machines using a client-side hypervisor. Each guest virtual machine requires $6\text{ GB}$ of RAM. The host operating system requires $4\text{ GB}$ of RAM, and the hypervisor itself requires an additional $2\text{ GB}$ of host memory for management overhead. To prevent system instability and performance issues caused by memory overcommitment, what is the minimum total amount of physical host RAM required?

$30\text{ GB}$ Cevap
B
$24\text{ GB}$
C
$26\text{ GB}$
D
$28\text{ GB}$

Cevap

The minimum total amount of physical host RAM required is

30\text{ GB}

The total physical RAM required on the host system must account for all guest virtual machines, the host operating system, and the hypervisor overhead. Multiplying four guest virtual machines by

6\text{ GB}

yields

24\text{ GB}

. Adding

4\text{ GB}

for the host operating system and

2\text{ GB}

for hypervisor management overhead results in a minimum host requirement of

30\text{ GB}

Adım Adım Çözüm

Calculate total RAM required for all guest virtual machines

4 \times 6\text{ GB} = 24\text{ GB}

Each of the four guest virtual machines requires

6\text{ GB}

of RAM.

Identify host operating system and hypervisor memory overhead requirements

4\text{ GB} \text{ (Host OS)} + 2\text{ GB} \text{ (Hypervisor Overhead)} = 6\text{ GB}

The host system must reserve memory for its own operating system and hypervisor management processes.

Sum total RAM requirements to determine minimum host physical memory

24\text{ GB} + 6\text{ GB} = 30\text{ GB}

Sufficient physical memory prevents host memory swapping, resource overcommitment, and system performance degradation.
