There are two separate issues here.  The first concerns which DNS server
to query, and the second concerns what TCP/IP routing to use to get to
the server in question.  If test.example.com is on a different subnet
than home.example.com, then you can configure your routers accordingly.

With respect to DNS, can your DNS server(s) be slaves for the

     example.com

zone(s)?  I can not give a more detailed answer without knowing more
specifics about your configuration and the subnets involved.
