A company wants a virtualization solution that runs directly on server hardware without requiring a host operating system, in order to maximize performance and resource allocation for multiple virtual machines. Which type of hypervisor should be deployed?
- AContainer engine
- BType 2 (hosted) hypervisor
- CType 1 (bare-metal) hypervisor
- DApplication virtualization
Show answer & explanationAnswer & explanation
Correct answer: C. Type 1 (bare-metal) hypervisor
A Type 1 (bare-metal) hypervisor installs directly on the physical hardware without an underlying host OS, providing better performance and resource allocation for enterprise virtualization. A Type 2 hypervisor runs on top of a host OS, adding overhead.
Why the other options are wrong
- A. Container engines virtualize at the OS level, not full VMs.
- B. Type 2 hypervisors require a host OS, adding overhead.
- D. Application virtualization isolates single apps, not entire systems.
Hypervisor Types
Type 1 hypervisors run directly on hardware (bare-metal); Type 2 hypervisors run on top of a host operating system.
- Type 1: e.g., VMware ESXi, Microsoft Hyper-V
- Type 2: e.g., VMware Workstation, VirtualBox
- Type 1 offers better performance for servers
- Type 2 easier for desktop testing/dev use
Memory trick: Type 1 sits on 'bare metal' like a king on a throne; Type 2 needs a host OS 'chair' first.
