Some Intel processors provide hardware-assisted virtualization to improve the fundamental flexibility and robustness of traditional software-based virtualization solutions by accelerating key functions of the virtualized platform.

About hardware-assisted virtualization, consider the following statements.

I. It enables the VMM to share I/O devices with several guest OSs at the same time.

II. It speeds up the transfer of platform control between the guest operating systems (OSs) and the virtual machine manager (VMM)/hypervisor.

III. It optimizes the network for virtualization with adapter-based acceleration.

IV. It is used in data centers for disaster recovery, high availability and business continuity, and in desktops to increase flexibility, improve security, and reduce costs.

Choose the correct alternative.
