Exam 70-741 topic 1 question 63 discussion

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/

Got this in a exam

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.

This was on the exam. Had my exam on November 27th 2020

Got this in a exam

New-NetLbfoTeam -TeamMembers <NIC Names> -Name "<Desciptive Name>" -TeamingMode SwitchIndependent -LoadBalancingAlgorithm TransportPorts

While configuring from VM, the only options are: Switch Independent Address Hash

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).

Answer is correct https://adamtheautomator.com/nic-teaming-windows-server/#switch-independent

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

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/

dritter is correct but this part of 70-740

I think you answer is wrong please read this https://docs.microsoft.com/en-us/windows-server/networking/technologies/nic-teaming/nic-teaming-settings
