What identies the functionality of virtual machines?
The hypervisor communicates on Layer 3 without the need for additional resources.
Each hypervisor supports a single virtual machine and a single software switch.
The hypervisor virtualizes physical components including CPU, memory, and storage.
Virtualized servers run eciently when physically connected to a switch that is separate from the hypervisor.
The hypervisor can run without a host operating system.
Correct answer
C. The hypervisor virtualizes physical components including CPU, memory, and storage.
Explanations
The very essence of virtualization lies in the hypervisor’s ability to simulate hardware components, enabling multiple operating systems to run simultaneously on a single physical system. When we talk about resource virtualization, we mean that the hypervisor is able to distribute portions of the physical server’s CPU, RAM and storage to each virtual machine, giving them the impression of running on their own dedicated hardware.
A. Although some hypervisors can interact with the network, the main role of the hypervisor is not direct communication on Layer 3 without other resources. This statement is therefore misleading.
B. This statement is incorrect because a hypervisor is designed to support multiple virtual machines on a single physical platform. It’s a misconception that he can only handle one.
D. The efficiency of virtualized servers does not depend solely on their connection to a switch. This is an inaccurate and simplistic assessment of the complexity of optimal virtualized server configurations.
E. Although some hypervisors, such as Type 1, operate directly on the hardware without requiring an underlying operating system, this is not a universal feature of all hypervisors.
