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.

management.
