Your network contains an Active Directory domain named contoso.com.
The domain contains a member server named Server 1.
Server1 runs Windows Server 2012 R2 and has the Hyper-V server role installed.
You create an external virtual switch named Switch1.
Switch1 has the following configurations:
– Connection type: External network
– Single-root I/O virtualization (SR-IOV): Enabled
Ten virtual machines connect to Switch1.
You need to ensure that all of the virtual machines that connect to Switch1 are isolated from the external network and can connect to each other only.
The solution must minimize network downtime for the virtual machines.
What should you do?
A.
Remove Switch1 and recreate Switch1 as an internal network.
B.
Change the Connection type of Switch1 to Private network.
C.
Change the Connection type of Switch1 to Internal network.
D.
Remove Switch1 and recreate Switch1 as a private network.
Explanation:
To CheckYou can change the connection type of a virtual switch from the virtual switch manager
without having to remove it.A private virtual network is isolated from all external network traffic on the virtualization
server, as well any network traffic between the management operating system and the
external network.
This type of network is useful when you need to create an isolated networking environment,
such as an isolated test domain.

Incorrect. Answer is D.
If SR-IOV is enabled, you cannot disable it after the creation of the virtual NIC. The only solution is to Remove Switch1 and configure it as a private network (to connect to the other VM’s only)

virtual switch, not NIC, sorry

D
As stated in previous answers:
The Virtual Switch Manager console displays the following warning: “SR-IOV can only be configured when the virtual switch is created. An external virtual switch with SR-IOV enabled cannot be converted to an internal or private switch.

Tnx you were a big help too!
Im leaving this test exam since I passed 840. Good luck for all! and remember know why the questions are right or wrong.
Last tip for the test takers. Always do a search on the main page http://www.aiotestking.com/microsoft with some part of the question so you see all the questions in all the versions. Read the comments there.

You cannot change the type of vswitch from external to private when SR-IOV is enabled at vswitch creation -> you need to recreate the vswitch.
