FC0-U71 Tech Concepts and Terminology Practice Question
Which of the following best describes the function of a hypervisor?
⚠ Common exam trap
A common mix-up: candidates confuse the hypervisor with an operating system or a cloud management platform; candidates might think a hypervisor is a specialized OS or that it handles cross-data-center orchestration, but its core function is local hardware virtualization.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
It allows multiple operating systems to run on a single physical machine
A hypervisor, also known as a virtual machine monitor (VMM), is software that creates and runs virtual machines by abstracting the underlying physical hardware. It allows multiple guest operating systems to run concurrently on a single physical host, each isolated from the others. This is the core function of virtualization, enabling efficient use of hardware resources and flexibility in IT environments.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
It is a type of operating system designed for servers
Why it's wrong here
A hypervisor is a virtualisation layer that runs beneath operating systems, not an operating system itself. It would be the answer if the question described a server-class OS, but here the requirement is the component that hosts and isolates guest VMs.
- ✗
It manages cloud resource allocation across multiple data centers
Why it's wrong here
A hypervisor creates and runs virtual machines by abstracting CPU, memory and I/O; it does not allocate cloud resources across data centres, which is the job of orchestration and scheduling platforms. It would be the answer if the question asked what runs and isolates guest VMs on one host.
- ✓
It allows multiple operating systems to run on a single physical machine
Why this is correct
A hypervisor abstracts physical CPU, memory and I/O, then allocates them to isolated virtual machines. Each guest runs its own operating system concurrently on the same host hardware, which is precisely the multi-OS capability the question asks about.
- ✗
It provides antivirus protection for virtual machines
Why it's wrong here
A hypervisor enforces isolation between virtual machines; it contains no antivirus engine or signature scanning. Antivirus runs inside each guest or on the host OS. It would be the answer if the question asked what separates VMs from each other on shared hardware.
