Question #: 63
Topic #: 1

HOTSPOT -
You have a Hyper-V host named Server1 that runs Windows Server 2016. Server1 has two network adaptors named NIC1 and NIC2. Server1 has two virtual switches named vSwitch1 and vSwitch2. NIC1 connects to vSwitch1. NIC2 connects to vSwitch2.
Server1 hosts a virtual machine named VM1. VM1 has two network adapters named vmNIC1 and vmNIC2. VmNIC1 connects to vSwitch1. VmNIC2 connects to vSwitch2.
You need to create a NIC team on VM1.
What should you run on VM1? To answer, select the appropriate options in the answer area.
NOTE: Each correct selection is worth one point.

The settings for a NIC Team in a VM have to be * Switch Independent * Address Hash (The only valid LoadBalancingAlgorithms in a Virtual Machine are 'TransportPorts', 'IPAddresses', and 'MacAddresses', which are forms of address hash load balancing algorithms) https://docs.microsoft.com/en-us/windows-server/networking/technologies/nic-teaming/nic-teaming https://docs.microsoft.com/en-us/powershell/module/netlbfo/new-netlbfoteam?view=win10-ps http://techgenix.com/windows-nic-teaming-using-powershell-part7/

Answer is correct. MS Docs say that you can only have 'Switch Independent' and 'Address Hash' on a VM NIC Team. TransportPorts one is of the 'hashing functions' of Address Hash. The other two functions are Source and Destination IP address and Source and Destination MAC Address.

Although this question seems to be "Host (Parent Partition)" command. The answer is using a host powershell command, not a VM powershell command...This is what we should do in this case... Create a team in a virtual machine PowerShell PS C:\> Set-VMNetworkAdapter -VMName <VMname> -AllowTeaming On PS C:\> New-NetLbfoTeam -Name "Team2" -TeamMembers "NIC1","NIC2" This set of commands allows teaming in virtual machines by using the AllowTeaming parameter of the Set-VMNetworkAdapter cmdlet and then creates a team named Team2 in the virtual machine specified by VMName. You must run the following command in the host (parent partition) with administrator rights.

The question says: What should you run on "VM1" not on Server1.

I believe the depicted answers are correct: 1) Teaming mode "Switch Independent" and load balancing mode "address hash" (https://docs.microsoft.com/en-us/windows-server/networking/technologies/nic-teaming/nic-teaming#virtual-machines-vms). 2) TransportPorts uses source and destination ports and IPs to create a hash (see -LoadBalancingAlgorithm under https://docs.microsoft.com/en-us/powershell/module/netlbfo/new-netlbfoteam?view=win10-ps#parameters). *) Hyper-V Port load balancing mode is NOT an option for creating teams within VMs (https://docs.microsoft.com/en-us/windows-server/networking/technologies/nic-teaming/nic-teaming-settings#hyper-v-port).

I would go with Switchindependent and Dynamic. Dynamic would automatically and equally distribute network traffic across the network. TransportPosts accepts inbound traffic on only one NIC.

The answer is correct since the only allowed Load balancing mode for a VM is "Address Hash" which by default calculates the Hash based on the source and destination TCP ports ('TransportPorts'). To change that you have New-netLFBOTeam to change the hash to either S/D IP only or S/D Mac addresses ('IPAddresses', or 'MacAddresses'). https://docs.microsoft.com/en-us/windows-server/networking/technologies/nic-teaming/nic-teaming-settings

I think the correct answers are: $var1="SwitchIndependent" and $var2= "HperVPort" Teamingmode: SwitchIndependent: specifies that a network switch configuration is not needed for the NIC team. When configuring teaming within a Hyper-V virtual machine, you must select this choice. This is also the default. Algorithm The possible values are: TransportPorts, IPAddresses, MacAddresses, HyperVPort. The default value is TranposrPorts, but I think in this case is HyperVPort. HyperVPort:Distributes network traffic based on the source virtual machine Hyper-V switch port identifier. This only makes sense if configuring within a VM. And we are configuring the team in VM. https://4sysops.com/archives/nic-teaming-with-powershell/
