You have a Hyper-V host named Server1 that runs Windows Server 2012 R2.Server1 has the virtual
switches listed in the following table.
You create a virtual machine named VM1.VM1 has two network adapters. One network adapter
connects to vSwitch1. The other network adapter connects to vSwitch2.You configure NIC teaming
on VM1.
You need to ensure that if a physical NIC fails on Server1, VM1 remains connected to the network.
What should you do on Server1?
A.
Run the Set-VmNetworkAdaptercmdlet.
B.
Add a new network adapter to VM1.
C.
Create a new virtual switch on Server 1.
D.
Modify the properties of vSwitch1 and vSwitch2.

Why not B? The nic team can only be attached to one switch, adding a 3 nic would allow connection to the 2nd switch.

To support this answer you have to know what Set-VmNetworkAdapter cmdlet does.
Parameter Set: ManagementOS
Set-VMNetworkAdapter -ManagementOS [-AllowTeaming ] [-CimSession <Microsoft.Man
https://technet.microsoft.com/en-us/library/hh848457.aspx
So rather than adding a third nic, they want you to disable teaming.

VM1 is a host running on server1
Server1 has two physical nics: Nic1 and Nic2.
They communicate via the vswitches with vm1.
You want to make sure that network will keep on running when one physical nic fails.
So you assign each switch their own physical nic.
Hence you need to configure each vswitch.

the Correct Answer is A
after search for long time i found that
in the setting of VM > Network Adapter > Advanced Features , in NIC Teaming section i found this note :-
” when this option is clare ‘not cheked’ , a team created in the guest operating system will lose connectivity if one of the physical network adapters stops”.
so i using this Command :
Get-VM -Name Lon-DC | Set-VMNetworkAdapter -AllowTeaming on
to make checkbox of NIC teaming is check of VM

Answer A is correct
this explains it very clearly:
By default, virtual machines are not configured to work with a teamed adapter. You must allow Virtual Machines to be configured with the NIC Teaming by executing the below PowerShell command:
Get-VM | Set-VMNetworkAdapter -AllowTeaming On

I think the answer is A,
the teaming mentioned in the question within the VM1, whereas the needed is to prevent the VM1 from loss the connectivity if one PHYSICAL NIC fails
