Your network consists of one Active Directory forest that contains one root domain and 10 child domains.
Administrators of the child domains frequently modify the records for authoritative DNS servers for the child domain DNS zones.
You need to recommend a solution to minimize the amount of manual configuration steps required to maintain name resolution on the network.
What should you recommend?
A.
On the child domain DNS servers, create stub zones for the root domain zone.
B.
On the child domain DNS servers, configure conditional forwarders for the parent domain.
C.
On the root domain DNS servers, create stub zones for the child domain zones.
D.
On the root domain DNS servers, configure delegation subdomain records for the child domains.
