http://www.zytrax.com/books/dns/

That is a good source to read up about bind configuration.

As a sidenote please be aware, that if someone directly queries your
ns1.exampleA.com for exampleB.com zone records he will get proper
answers. If you would need to prevent this for any reason you would need
a extended bind config design using views.

While the zytrax book has lessons about views you can too find a resource in
