You only need three lines of PowerShell to deploy an NAT-enabled virtual switch on a Windows 10 or WS2016 Hyper-V machine. The first step is to create an Internal virtual switch; this is a switch that is not connected to a physical NIC on the host; instead, the host management OS has a virtual NIC that is connected to the virtual switch; the end result is that (to begin with) that virtual machines on the internal virtual switch can talk to the host, but they cannot talk to the network that the host is connected to. 1).New-VMSwitch -SwitchName “NATSwitch” -SwitchType Internal The next step updates the virtual NIC that connects the host management OS to the internal virtual switch. The following command will assign an IP address to this virtual NIC, and this IPv4 address will be the default gateway for the network on NAT network that we are creating.

Answer is correct. Different types of switch: External – This type of switch is bound to the physical network cards located in the host. As you would imagine, they provide VMs located on these switches with access to the physical network the Hyper-V host is connected to. The External switch can also share management traffic as well as VM traffic on the same switch and this is one of the options that can be set when creating the external switch. Internal – This switch is not bound to a physical network card so it only allows traffic between VMs and the host itself. However, a new addition to the Internal switch functionality in 2016 is the addition of the NAT forwarding internal switch which does allow external connectivity via NAT from the Hyper-V host. Private – This type of switch is only used for virtual machines to communicate with each other. This type of switch might be useful for certain specific types of traffic such as cluster network if only using one host as it can’t be utilized between hosts.

I think the given answers are correct. This method using New-NetNat is for Hyper-V and virtual machin. If these aren't used, also New-NetNat can't be used.

"VM1 can access the resources on the corporate network." The switch must be external

In the spirit of which is the "most correct"...... you would need to create a new switch New-NetIPAddress (give it an address) new-netnat (tell it to be a NAT) This is correct, but will NOT likely be on the exam
