What are two fundamentals of virtualization?

The environment must be configured with one hypervisor that serves solely as a network manager to monitor SNMP traffic

It allows logical network devices to move traffic between virtual machines and the rest of the physical network

It allows multiple operating systems and applications to run independently on one physical server.

It allows a physical router to directly connect NICs from each virtual machine into the network

It requires that some servers, virtual machines and network gear reside on the Internet
