What Is a Type 1 Hypervisor?
A company runs multiple virtual machines on a single physical server. The hypervisor is installed directly on the server hardware and does not require an underlying operating system. This configuration is an example of which of the following?
Quick Answer
The answer is a Type 1 hypervisor, also known as a bare-metal hypervisor, because it is installed directly on the server hardware without requiring an underlying operating system. This configuration is correct because the hypervisor has direct access to physical resources like CPU, memory, and I/O, which minimizes overhead and allows multiple virtual machines to run efficiently in an enterprise data center. On the CompTIA A+ Core 1 220-1101 exam, this question tests your ability to distinguish between Type 1 and Type 2 hypervisors; a common trap is confusing Type 1 with hosted hypervisors that run on top of an OS, like VirtualBox or VMware Workstation. To remember, think of Type 1 as “bare metal” — it touches the metal directly, while Type 2 sits on an OS like a guest.
⚠ Common exam trap
Many exam-takers confuse 'Type 1' with 'Type 2' by focusing on the presence of a management OS (like in Hyper-V) rather than the fact that the hypervisor core runs directly on hardware, leading them to incorrectly select Type 2.

Correct answer & explanation
✓
Type 1 hypervisor
A Type 1 hypervisor, also known as a bare-metal hypervisor, runs directly on the physical hardware without requiring an underlying operating system. This configuration is used in enterprise data centers to host multiple virtual machines efficiently, as the hypervisor has direct access to hardware resources like CPU, memory, and I/O, minimizing overhead.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Type 2 hypervisor
Why it's wrong here
A Type 2 hypervisor runs as an application atop a host operating system, so it cannot satisfy the bare-metal, OS-less requirement described. It is tempting because Type 2 products such as VirtualBox and VMware Workstation are common on desktops, where hosting VMs alongside a general-purpose OS is exactly the intended design.
When this WOULD be correct
This option would be correct in a scenario where the hypervisor is installed on a host operating system (e.g., Windows or Linux) and manages guest VMs as applications. For example, a question describing VMware Workstation or Oracle VirtualBox running on a desktop OS.
- ✗
Infrastructure as a Service
Why it's wrong here
IaaS is a cloud service model delivering provider-hosted compute, storage and networking over the internet; it says nothing about a hypervisor running directly on local server hardware. It is tempting because IaaS tenants do run multiple VMs on shared physical hosts, but the provider, not the company, owns and manages that hardware.
When this WOULD be correct
A question asking: 'A company uses a cloud provider to rent virtual machines, storage, and networking resources, managing the operating systems and applications themselves. This model is known as which of the following?' would make IaaS the correct answer.
- ✓
Type 1 hypervisor
Why this is correct
A Type 1 hypervisor runs directly on bare metal, with guest operating systems layered above it and no host OS beneath. That matches the stem's constraint of hypervisor-on-hardware, whereas Type 2 installs atop a conventional operating system.
- ✗
Virtual Desktop Infrastructure
Why it's wrong here
VDI describes delivering virtualised desktop sessions to end users, not the hypervisor architecture installed on the physical host. It is tempting because VDI environments do run many VMs on one server, yet the stem specifies no desktop-delivery requirement, only the bare-metal hypervisor placement.
When this WOULD be correct
A question asking about a solution where users access virtual desktops hosted on a central server, with each user having a personalized desktop environment, would make VDI the correct answer.
Option-by-option analysis
Why each answer is right or wrong
Understanding why wrong answers are wrong — and when they would be correct — is what separates a 750 score from a 900. The 220-1101 exam frequently reuses these exact scenarios with slightly different constraints.
✓Type 1 hypervisorCorrect answer▾
Why this is correct
A Type 1 hypervisor runs directly on bare metal, with guest operating systems layered above it and no host OS beneath. That matches the stem's constraint of hypervisor-on-hardware, whereas Type 2 installs atop a conventional operating system.
✗Type 2 hypervisorWrong answer — click to see why▾
Why this is wrong here
A Type 2 hypervisor runs on top of an operating system, not directly on hardware. The question states the hypervisor is installed directly on server hardware without an underlying OS, which describes a Type 1 hypervisor.
★ When this WOULD be the correct answer
This option would be correct in a scenario where the hypervisor is installed on a host operating system (e.g., Windows or Linux) and manages guest VMs as applications. For example, a question describing VMware Workstation or Oracle VirtualBox running on a desktop OS.
Why candidates choose this
Candidates may confuse Type 1 and Type 2 hypervisors, or think that any hypervisor managing VMs is Type 2, overlooking the key distinction of whether it runs directly on hardware or on an OS.
✗Infrastructure as a ServiceWrong answer — click to see why▾
Why this is wrong here
Infrastructure as a Service (IaaS) is a cloud computing model that provides virtualized computing resources over the internet, not a type of hypervisor installation. The question describes a Type 1 hypervisor, which runs directly on hardware, whereas IaaS is a service model, not a hypervisor type.
★ When this WOULD be the correct answer
A question asking: 'A company uses a cloud provider to rent virtual machines, storage, and networking resources, managing the operating systems and applications themselves. This model is known as which of the following?' would make IaaS the correct answer.
Why candidates choose this
Candidates may confuse the concept of virtualization with cloud service models, thinking that running VMs on a server is equivalent to IaaS, or they may incorrectly associate 'infrastructure' with the physical server itself.
✗Virtual Desktop InfrastructureWrong answer — click to see why▾
Why this is wrong here
Virtual Desktop Infrastructure (VDI) refers to hosting desktop environments on a central server and delivering them to clients, not the hypervisor type. The question describes a Type 1 hypervisor installed directly on hardware, which is unrelated to VDI.
★ When this WOULD be the correct answer
A question asking about a solution where users access virtual desktops hosted on a central server, with each user having a personalized desktop environment, would make VDI the correct answer.
Why candidates choose this
Candidates may confuse VDI with virtualization in general, or think that running multiple VMs implies a desktop virtualization scenario, leading them to select VDI without recognizing the hypervisor type distinction.

Same concept, more angles
2 more ways this is tested on 220-1101
These questions test the same concept from different angles. Work through them to make sure you can recognise it however the exam phrases it.
Variation 1. An organization plans to consolidate its physical servers by running multiple virtual machines on a single host. The administrator needs to choose a hypervisor that offers the best performance and direct access to hardware resources for the VMs. The host server will only run the hypervisor and its VMs. Which of the following hypervisor types is the BEST choice for this scenario?
medium- A.Type 2 hypervisor
- ✓ B.Type 1 hypervisor
- C.Container-based virtualization
- D.Cloud-based hypervisor as a service
Why B: A Type 1 hypervisor (bare-metal) runs directly on the host hardware without an underlying operating system, providing near-native performance and direct access to CPU, memory, and I/O resources. This is ideal for the scenario where the host server is dedicated solely to running the hypervisor and its VMs, as it minimizes overhead and maximizes resource efficiency.
Variation 2. An IT department runs several virtualized database servers on a single physical host using a Type 2 hypervisor. They plan to replace the Type 2 hypervisor with a Type 1 hypervisor to improve performance. Which of the following is a primary advantage of a Type 1 hypervisor in this scenario?
hard- A.Lower licensing costs compared to Type 2 hypervisors
- ✓ B.Improved performance due to direct access to physical hardware without a host operating system
- C.Easier to install and configure than Type 2 hypervisors
- D.Supports a wider variety of guest operating systems
Why B: A Type 1 hypervisor (bare-metal) runs directly on the physical hardware without a host OS, eliminating the overhead of an intermediate operating system layer. This reduces latency and CPU/memory consumption, directly improving performance for virtualized database servers compared to a Type 2 hypervisor that relies on a host OS for resource management.
