A company wants to run multiple isolated operating systems directly on server hardware for maximum performance, without installing a host operating system first. Which virtualization approach should be used?

  1. AType 1 hypervisor
  2. BType 2 hypervisor
  3. CApplication virtualization
  4. DContainer-based virtualization
Show answer & explanation

Correct answer: A. Type 1 hypervisor

A Type 1 (bare-metal) hypervisor installs directly on the physical server hardware and manages guest virtual machines without needing an underlying host OS, providing better performance and resource efficiency than Type 2 hypervisors.

Why the other options are wrong

  • B. Type 2 hypervisors run on top of an existing host OS, adding overhead and reducing performance.
  • C. Application virtualization isolates individual apps, not entire operating systems.
  • D. Containers share the host OS kernel and are not full OS virtualization on bare metal.

Type 1 vs Type 2 Hypervisor

Type 1 (bare-metal) hypervisors run directly on hardware; Type 2 (hosted) hypervisors run as an application on top of an existing OS.

  • Type 1 examples: VMware ESXi, Microsoft Hyper-V
  • Type 2 examples: VMware Workstation, VirtualBox
  • Type 1 offers better performance for data center use

Memory trick: Type 1 = bare metal, no middleman OS.
