350-401 Question 83
Single answerAn enterprise network engineer is setting up a virtualization environment to host multiple virtual machines for critical applications. The engineer decides to use a hypervisor that installs directly on the physical hardware without requiring an underlying operating system. Which type of hypervisor is the engineer deploying?
- A
Type 1 Hypervisor
- B
Type 2 Hypervisor
- C
Container-based Virtualization
- D
Bare-metal Operating System
Show answer and explanation
Correct answer: A
Explanation
Type 1 Hypervisors are the correct choice for enterprise-grade virtualization environments where high performance and direct access to hardware resources are critical. Unlike Type 2 Hypervisors, which rely on an existing operating system, Type 1 Hypervisors install directly on hardware, making them more efficient and reliable for hosting multiple virtual machines.
- A. Correct.
Type 1 Hypervisors, also called bare-metal hypervisors, run directly on physical hardware without requiring an operating system. They are designed for high performance and efficient resource utilization, making them ideal for enterprise environments.
- B. Incorrect.
Type 2 Hypervisors require a host operating system to run, as they are installed as an application on top of the OS. This type of hypervisor is not directly installed on the hardware and is generally less efficient for enterprise-grade solutions.
- C. Incorrect.
Container-based virtualization uses containers to isolate applications, but it is not classified as a hypervisor. It is a different virtualization method and does not involve hosting virtual machines.
- D. Incorrect.
A bare-metal operating system is not a type of hypervisor. It refers to an operating system installed directly on hardware without a virtualization layer.
