CompTIA A+ Core 1 (220-1201)Virtualization and Cloud ComputingEasy
A technician is setting up a new server that will host multiple virtual machines. To ensure optimal performance and isolation for each VM, what type of hypervisor should be installed directly on the server's hardware?
- AVirtual Desktop Infrastructure (VDI) broker
- BType 1 Hypervisor
- CContainer Engine
- DType 2 Hypervisor
Show answer & explanationAnswer & explanation
Correct answer: B. Type 1 Hypervisor
A Type 1 hypervisor, also known as a 'bare-metal' hypervisor, runs directly on the host hardware. This provides superior performance, security, and isolation for virtual machines, making it ideal for server virtualization.
Why the other options are wrong
- A. A VDI broker manages connections to virtual desktops, not the underlying virtualization technology.
- C. A container engine manages containers, which are different from virtual machines and offer less isolation.
- D. Type 2 hypervisors run as an application on top of a host operating system, introducing overhead and reducing performance.
Type 1 Hypervisor
A hypervisor that runs directly on the host computer's hardware, controlling the hardware and managing guest operating systems.
- Also known as 'bare-metal' hypervisor.
- Offers better performance and security than Type 2.
- Commonly used in data centers and server virtualization.
Memory trick: One is bare, Two is hosted.
