A practice test that came with the MS Press 70-291 book says the
following, and I'm not really convinced that it is right, so I'd like
to hear an mcse's opinion:

A dns server that is hosting a delegated zone must also contain a
secondary zone for the parent domain, so that computers in the
delegated zone can resolve names for hosts in the parent domain.
(that's my convoluted wording, not the book's)

I don't see why the secondary zone would be necessary. Computers in
the delegated domain would just ask their dns server (ie, the one in
that delegated zone) for the address of a host, and that dns server
should just perform recursion as usual, whether the destination host
is in the parent domain or anywhere else in the world. Am I wrong?

Thank you!
