A test virtual machine must not reach the production servers. The host already has a virtual switch with no path to those servers. How should the guest be connected?
Select an answer to reveal the explanation.
Short Explanation
You keep the test guest away from production by connecting its virtual adapter to the isolated virtual switch. A route onto production, a RAID volume, and a loopback plug do not provide that network separation.
Full Explanation
A virtual machine reaches the network only through the virtual switch its adapter is attached to. Connecting the guest’s virtual network adapter to the isolated switch, which has no path to production, keeps the test guest away from those servers. Giving the guest a route onto the production network does the opposite of the requirement. Storing the guest on a RAID volume protects or stripes disks; it does not isolate a network. Inserting a loopback plug tests a physical port; it is not a virtual switch. Exam caveat: a second adapter left on the production switch would bypass the isolation, so check every virtual NIC, not only the first. As a practical check, ping a production server from the guest and confirm there is no reply before the test begins. Record the result on the ticket before closing the call; the expected result is silence.
