Your network consists of an Active Directory forestthat contains two domains. All servers run WindowsServer
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 eachdomain 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.
