350-401 · Question #1088
Which virtualization component creates VMs and performs hardware abstraction that allows multiple VMs to run at the same time?
The correct answer is C. hypervisor. A hypervisor is the core virtualization component responsible for creating and managing virtual machines, abstracting hardware to enable multiple VMs to run concurrently on a single physical host.

Why each option
A hypervisor is the core virtualization component responsible for creating and managing virtual machines, abstracting hardware to enable multiple VMs to run concurrently on a single physical host.
A container is a lightweight, isolated execution environment that shares the host OS kernel and virtualizes the OS level, not the hardware.
Docker is a popular platform for developing, shipping, and running applications in containers, but it is not the underlying virtualization component that abstracts hardware for VMs.
A hypervisor, also known as a virtual machine monitor (VMM), is software or firmware that creates and runs virtual machines (VMs). It provides a virtual operating platform to guest VMs and performs hardware abstraction, allowing multiple operating systems to share the host's physical hardware resources simultaneously.
rkt (now deprecated) was an open-source container runtime, similar to Docker, focusing on container execution rather than hardware virtualization.
