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.

2).New-NetIPAddress -IPAddress 172.16.1.1 -PrefixLength 16 -InterfaceAlias "vEthernet (NATSwitch)" The final step in the process will configure the network address of the NAT network that will run on the virtual switch; this is the private range of addresses that the virtual machines will use in the abstracted virtual switch; note that the IPv4 address in the previous step must be in this range. 3).New-NetNAT -Name "NATNetwork" -InternalIPInterfaceAddressPrefix 172.16.0.0/16

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.

I think D is correct anwser. Common questions, including this quesiton are as follow. Net solution has two types method. 1)You use New-NetNAT**** cmdlet. >>Q152 in topic 1 2)You use RAS and NAT in RAS. >>Q122 in topic 1

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

The corporate network has a network ID which is different from the one that the VM using, i.e. different IP ranges. How you gonna translate between them? you'll have to set up NAT. Since you gonna use NAT you have to create an Internal virtual switch. So the provided answer is correct (Internal & New-NetNat).

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
