Question
A company has a Windows Server 2012 R2 server that has the Hyper-V role installed. The server has a single processor and a single 10-gigabit network interface card (NIC). 12 virtual machines (VMs) run on the server. You need to configure Hyper-V to allow higher network throughput and reduce processing overhead related to network operations. What should you do?
Options
- ARun the Windows PowerShell command Set-VMNetworkAdapter -VmqWeight 0 on the VMs.
- BIn Hyper-V Manager, disable the protected network option for all NICs on the VMs.
- Cin Hyper-V Manager, enable the Single Root I/O Virtualization (SR-IOV) option on the VMs.
- DDisable Internet Protocol security (IPsec) task offloading on the VMs.
