Which of the following supports virtualization?

AType 1 hypervisor(also known as a bare-metal hypervisor) is installed directly on the hardware and is designed to manage multiple virtual machines. It is the most common type of hypervisor used in virtualization environments.

Type 1 hypervisor (Answer A):This is a core technology that enables virtualization by running virtual machines directly on the physical hardware.

Bare-metal installation (Option B):Refers to installing an OS or hypervisor directly on hardware, but doesn't inherently support virtualization unless it's a hypervisor.

Server-level redundancy (Option C):This provides fault tolerance but is not related to virtualization.

Active-active load balancing (Option D):Refers to distributing workloads across multiple servers, not directly tied to virtualization.
