Implementing and Operating Cisco Enterprise Network Core Technologies (ENCOR) — Question 279

What is a characteristic of a virtual machine?

Answer options

• A. It must run the same operating system as its host.
• B. It is deployable without a hypervisor to host it.
• C. It must be aware of other virtual machines, in order to allocate physical resources for them.
• D. It relies on hypervisors to allocate computing resources for it.

Correct answer: D

Explanation

The correct answer is D because virtual machines rely on hypervisors to manage and allocate the physical computing resources they need to function. Option A is incorrect as a virtual machine can run different operating systems than its host. Option B is wrong because a hypervisor is necessary for the deployment of a virtual machine. Option C is not accurate since a virtual machine does not need to be aware of other virtual machines to allocate resources.
