This one being the one I was most interested in, it is saying that the
NIC that is is the default NIC (unless it knows otherwise).

Actually the question was regarding whether all NICs (well their TCP/IP
configuration, really) register themselves with DNS.

There you have it.

When the question is asked, there will be three results.

I suspect this may not be what you want. I could be wrong, but unless
you have other requirements, you may not want all NICs to be registering
themselves - maybe only one.

If you've left it to defaults, it will.

You can check by opening the DNS GUI / MMC and getting the properties of
the server.
