I'm studying for my 70-291 exam and need to clarify the advantages of a stub zone vs. a delegation. From what I understand a stubzone is a kind of superset of a delegation with the extra benefits being automatic updates of NS records in the child zone and also not being tied to the parent in domain namespace. ie) A stub zone in mel.company1.intranet can point to syd.company2.intranet directly where as a delegation would have to be done on company2.intranet to point to syd.company2.intranet Is my understanding of this correct? Can anyone tell me what a delegation can do that a stub zone can't? Thanks!
