What are two fundamentals of virtualization? (Choose two.)

One of the core tenets of virtualization is the ability to abstract the underlying hardware, allowing a hypervisor to host several guest operating systems and their applications as virtual machines, all sharing the same physical server resources. This increases hardware utilization and reduces physical infrastructure.

Virtual machines use virtual network interface cards (vNICs) that connect to virtual switches, not directly to a physical router, to communicate within the virtual environment and with the outside world.

A hypervisor's primary role is to create and manage virtual machines and their access to physical resources; it does not solely serve as a network router, although some hypervisors have networking capabilities.

In a virtualized environment, logical network devices, such as virtual switches, are essential for connecting virtual machines (VMs) to each other and providing a path for their traffic to reach the physical network interfaces, thus enabling communication with the rest of the network and external resources.

While cloud computing (which uses virtualization) often involves resources on the internet, virtualization itself does not *require* any servers, VMs, or network gear to reside on the internet; it can be entirely on-premises.
