Which cmdlet will enable RSS on any NIC on a VM

Set-NetAdapterRss -Name * -Enabled $true

Which service in Server 2016 is a network layer, 5-tuple (protocol, source and destination port numbers, source and destination IP addresses), stateful, multi tenant firewall that can install and configure firewall policies to help protect their virtual network from unwanted traffic originating from internet and intranet networks?

Datacentre Firewall

What can you use to manage the following physical and virtual network infrastructure components centrally?

Hyper-V VMs

Virtual Switches

Physical network Switches

Physical network routers

Firewall software

Network Controller

What level OS must a guest be to enable SR-IOV?

W8 - clients

S2012 - hosts

What level OS must a host be to enable SR-IOV?

S2012

What should be used to forward network traffic between a tenant virtual network and a tennant external network?

GRE over IKEv2 S2S.

You want to distribute network traffice amoung multiple VMs on a single S2016 Hyper-V host with a vSwitch. You have 8 physical 10GB NIC and 32 logical processors. You want to increase the scalbility of the VMs networking. What configuration setting do you have to verify of configure?

1. Verify thet hyper-threading is enabled 2. Configure the Teaming mode as switch independent 3. Configure the load balancing distribution mode as Dynamic 4. Enable VMQ on the NIC 5. Set base processot number and max processor number with **Set-NetAdapterVmq** 6. Enable RSS with the Enable-NetAdapterRSS cmdlet

You are configuring NIC teaming. You have chosen to implement Static teaming as the teaming mode. What is your next step?

Static teaming requires that your Ethernet switches must be configured for NIC teaming per the 802.3ad standard.

When you are configuring SET in a test network, you can only use one Teaming mode. What is it?

Switch independent mode is the only supported teaming mode in SET.

You try to enable RSS in a virtual machine running Windows Server. You are unable to do so. What could the possible reason(s) be?

In order to enable RSS on a virtual machine, your network adapters must support the VMQ feature.

You decide to implement QoS over DCB. What are the high-level steps that you must complete?

The high-level steps are: 1. Enable DCB on your physical switches 2. Create QoS rules 3. Install the DCB feature on your server(s) 4. Define the traffic classes 5. Enable the DCB settings 6. Enable DCB on your network adapters

What Windows PowerShell cmdlet can you use to enable RDMA on your server’s net- work adapter?

You can enable RDMA on your network adapter, assuming they are RDMA-capable, by using the Windows PowerShell Enable-NetAdapterRdma cmdlet.

What is the main purpose of using network virtualization?

You can use network virtualization to manage network traffic by creating multiple virtual networks, logically isolated, on the same physical network.
