Answer options

• A. It allows logical network devices to move traffic between virtual machines and the rest of the physical network.
• B. It allows multiple operating systems and applications to run independently on one physical server.
• C. It allows a physical router to directly connect NICs from each virtual machine into the network.
• D. It requires that some servers, virtual machines, and network gear reside on the Internet.
• E. The environment must be configured with one hypervisor that serves solely as a network manager to monitor SNMP traffic.

Correct answer: A, B

Explanation

The correct answers, A and B, highlight the core functionalities of virtualization, which include enabling multiple OS and applications to run on a single hardware platform and facilitating network communication between virtual machines and the physical network. The other options either describe scenarios that are not fundamental to virtualization, such as direct connections to a physical router (C), requirements for Internet presence (D), or specific configurations of hypervisors that are not essential (E).
