Actual exam question from Microsoft's 70-417

Question #: 148
Topic #: 1

You have a server named Server1 that runs Windows Server 2012 R2. Server1 has the Hyper-V server role installed. On Server1, you create a virtual machine named VM1.
VM1 has a legacy network adapter.
You need to assign a specific amount of available network bandwidth to VM1.
What should you do first?

A. Add a second legacy network adapter, and then run the Set-VMNetworkAdaptercmdlet.
B. Add a second legacy network adapter, and then configure network adapter teaming.
C. Remove the legacy network adapter, and then run the Set-VMNetworkAdaptercmdlet.
D. Remove the legacy network adapter, and then add a network adapter.

Show Suggested Answer

Suggested Answer: D 🗳️
Explanation -
The legacy adapter doesn't support bandwidth management (check screenshots below). and if we remove the legacy network adapter without adding a new one, what would we set with Set-VMNetworkAdapter? so the complete answer should be "Remove the legacy network adapter, then add a network adapter, and then run the Set
-VMNetworkAdapter cmdlet" but we're asked for what we should do FIRST.

(You'll see in the next screenshot that for a "Network adapter, bandwidth is managed here) http://technet.microsoft.com/en-us/library/hh848457.aspx
Set-
VMNetworkAdapter Configures features of the virtual network adapter in a virtual machine or the management operating system.[...]
-
MaximumBandwidth<Int64>Specifies the maximum bandwidth, in bits per second, for the virtual network adapter. The specified value is rounded to the nearest multple of eight. Specify zero to disable the feature.

Bandwidth management -
Bandwidth management is a new feature in Windows Server 2012 R2 Hyper
-V that enables you to set both a minimum and maximum Mbps of throughput for any virtual network adapter. In Windows Server 2008 R2, you could configure a maximum bandwidth but not a minimum. Now you can configure both a minimum and a maximum for each virtual network adapter. You enable and configure bandwidth management on a virtual network adapter in the settings of a VM, as shown in Figure 3-12. For either the Minimum Bandwidth or Maximum Bandwidth setting, configuring a value of 0 leaves that setting unrestricted.

You can also use the Set-VMNetworkAdapter to configure minimum and maximum bandwidth on a virtual network adapter. As an alternative to specifying a value for Mbps, you can use this cmdlet to specify a relative bandwidth weight between 0 and 100 relative to other virtual network adapters. To ensure that all virtual network adapters are given an equal minimum or maximum bandwidth, you can assign the same bandwidth weight to all adapters.
