Exploring virtual networks

A virtual network is very similar to a physical network in many ways, but for the Security+ exam, we must know the concepts of virtualization. To be able to host a virtual environment, we must install a hypervisor on a computer hosting the virtual machines. There are two different types of hypervisor:

Type 1 hypervisor: This is a enterprise version that can be installed on a computer without an operating system, called bare metal. Examples are VMWare ESX, Microsoft's Hyper V, or Zen used by Amazon Web Services (AWS).

Type 2 hypervisor: This needs an operating system, such as Server 2016 or Windows 10, and then the hypervisor is installed like an application. An example of a Type 2 hypervisor is Oracle's VM VirtualBox or Microsoft's virtual machine.
