220-1101 Virtualization and Cloud Computing Practice Question
A company plans to run multiple virtual servers on a single physical host to reduce hardware costs. The IT team wants direct hardware access for each virtual machine to maximize performance and minimize latency. Which of the following is the most appropriate hypervisor type to deploy?
⚠ Common exam trap
CompTIA often tests the misconception that 'Type 2 hypervisors are easier to manage and therefore better for performance,' but the trap here is that direct hardware access and minimal latency require a Type 1 hypervisor, not a Type 2 or container-based solution.
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
✓
Type 1 hypervisor (bare-metal) installed directly on the server hardware.
A Type 1 hypervisor (bare-metal) runs directly on the physical hardware without an underlying operating system, allowing each virtual machine to have direct, low-latency access to CPU, memory, and I/O devices. This architecture minimizes overhead and maximizes performance, making it the ideal choice when the requirement is direct hardware access for each VM.
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 1 hypervisor (bare-metal) installed directly on the server hardware.
Why this is correct
Type 1 hypervisors like VMware ESXi or Microsoft Hyper-V run directly on the server hardware without an intervening operating system. The hypervisor itself handles CPU scheduling, memory isolation, and I/O device access, giving each virtual machine near-native performance and direct hardware access. This minimal abstraction layer ensures low latency and high throughput, which is why it is the standard for production server virtualization.
- ✗
Type 2 hypervisor installed on top of a general-purpose operating system.
Why it's wrong here
A Type 2 hypervisor relies on a host operating system to mediate all hardware access, introducing additional abstraction layers that increase latency and degrade performance. This directly contradicts the requirement for direct hardware access to each virtual machine. It is tempting because Type 2 hypervisors simplify management and driver support for desktop virtualisation or testing environments, where maximum performance is not the priority.
When this WOULD be correct
When the question specifies that the hypervisor must run on existing desktop hardware with a familiar OS, and performance requirements are moderate, such as for development/testing environments where ease of setup is prioritized over raw performance.
- ✗
Container-based virtualization running on the host OS.
Why it's wrong here
Container-based virtualization uses OS-level isolation, where all containers share the same host operating system kernel and drivers. Because there is no separate kernel per workload, containers cannot provide direct hardware access or run independent operating systems, and they rely on the host kernel for resource management. This makes them efficient for lightweight application deployment but fundamentally unsuitable for full hardware-level server virtualization.
- ✗
A virtual desktop infrastructure (VDI) solution.
Why it's wrong here
VDI (Virtual Desktop Infrastructure) is a delivery platform that hosts desktop operating systems in VMs and streams the graphical user interface to end-user devices. It is designed for user-centric desktop sessions, not for headless server workloads, and it typically runs on top of an underlying hypervisor rather than being a hardware-virtualization layer itself. Choosing VDI to virtualize multiple servers would add an unnecessary desktop-management layer and would not itself provide direct hardware access to the VMs.
When this WOULD be correct
A company needs to provide remote, secure desktop environments to employees from a centralized server, reducing endpoint management costs and ensuring data security. VDI would be the correct answer for such a desktop virtualization scenario.
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.

Why this is wrong here
A Type 2 hypervisor runs on top of a general-purpose OS, adding overhead and preventing direct hardware access, which contradicts the requirement for maximum performance and minimal latency.
★ When this WOULD be the correct answer
When the question specifies that the hypervisor must run on existing desktop hardware with a familiar OS, and performance requirements are moderate, such as for development/testing environments where ease of setup is prioritized over raw performance.
Why candidates choose this
Candidates may confuse Type 2 hypervisors with Type 1, or assume that any hypervisor provides direct hardware access, overlooking the performance penalty of the host OS layer.
✗A virtual desktop infrastructure (VDI) solution.Wrong answer — click to see why▾
Why this is wrong here
VDI is a desktop virtualization solution that provides remote desktops to users, not a hypervisor for running multiple virtual servers with direct hardware access. It does not manage virtual machines on a single physical host for server consolidation.
★ When this WOULD be the correct answer
A company needs to provide remote, secure desktop environments to employees from a centralized server, reducing endpoint management costs and ensuring data security. VDI would be the correct answer for such a desktop virtualization scenario.
Why candidates choose this
Candidates may confuse VDI with server virtualization because both involve virtual machines, but VDI is specifically for desktop delivery, not for running server workloads with direct hardware access.
