You have a file server named Server1 that runs Windows Server 2012 R2. Server1 has following hardware configurations:
• 16 GB of RAM
• A single quad-core CPU
• Three network teams that have two network adapters each
You add additional CPUs and RAM to Server1. You repurpose Server1 as a virtualization host. You install the Hyper-V server role on Server1. You need to create four external virtual switches in Hyper-V.
Which cmdlet should you run first?
A. Add-NetLbfoTeamNic
B. Set-NetAdapter
C. Remove- NetLbfoTeam
D. Add-VMNetworkAdapter
Correct Answer: C
Explanation/Reference:
Explanation:
Here we’re talking about hardware network adapters which belong to NIC teams Each external virtual switch must be connected to a NIC or a NIC team, so we need 4 NICs or NIC teams but currently only have 3 teams available.
=>we need to break a team first and then connect the two last external virtual switches to each of the 2"liberated" NIC (another solution could be to add one physical NIC and connect the last external virtual switch to it or add several (two or more) NICs, create a NIC team containing them and connect the external virtual switch to the NIC team)
NIC Teaming (NetLBFO) cmdlets in Windows PowerShell
Remove-NetLbfoTeam: Removes the specified NIC team from the host.
NIC Teaming Overview
NIC Teaming, also known as load balancing and failover (LBFO), allows multiple network adapters on a computer to be placed into a team for the following purposes:
Bandwidth aggregation Traffic failover to prevent connectivity loss in the event of a network component failure
This feature has been a requirement for independent hardware vendors (IHVs) to enter the server network adapter market, but until now NIC Teaming has not been included in Windows Server operating systems.
Requirements NIC Teaming requires the presence of a single Ethernet network adapter, which can be used for separating traffic that is using VLANs. All modes that provide fault protection through failover require at least two Ethernet network adapters. Windows Server?2012 supports up to 32 network adapters in a team.
