Your network consists of an Active Directory forest that contains two domains. All servers run Windows Server 2008 R2. All domain controllers are configured as DNS Servers. You have a standard primary zone for dev. contoso.com that is stored on a member server. You need to ensure that all domain controllers can resolve names from the dev.contoso.com zone. What should you do?
A.
On the member server, create a stub zone.
B.
On the member server, create a NS record for each domain controller.
C.
On one domain controller, create a conditional forwarder. Configure the conditional forwarder to replicate to all DNS servers in the forest.
D.
On one domain controller, create a conditional forwarder. Configure the conditional forwarder to replicate to all DNS servers in the domain.
