What software allows you to define VMs and manage resource allocation and sharing among them on a host computer?

• Hypervisor

• NFV (Network Functions Virtualization)

• SDN (software-defined networking)

• Terminal emulation

What virtual, logically defined device operates at the Data Link layer to pass frames between nodes?

• Virtual firewall

• Virtual switch

• Virtual router

• Virtual load balancer

With which network connection type does the VM obtain IP addressing information from its host?

• Bridged mode

• Managed mode

• NAT mode

• Host-only mode

True or False: VMs that must be available at a specific address, such as mail servers or Web servers, should be assigned host-only network connections.

• True

• False

In which networking mode, can VMs on one host exchange data with each other and with their host, but they cannot communicate with any nodes beyond the host?

• host-only

• bridged

• NAT

• network-only

A Type 2 hypervisor installs on a computer before any OS, and is therefore called a bare-metal hypervisor.

• True

• False

Which statement regarding the use of a bridged mode vNIC is accurate?

• The vNIC will its own IP address on the physical LAN.

• The vNIC will be assigned a NAT-ed IP address.

• The vNIC will only be able to communicate across the bridge to the host PC.

• The vNIC will utilize the host PC's IP address.

In a software defined network, what is responsible for controlling the flow of data?

• flow director

• vRouter

• SDN controller

• SDN switch
