Contoso Ltd. has a single Active Directory forest that has five domains. Each domain has two DNS
servers. Each DNS server hosts Active Directory-integrated zones for all five domains. All domain
controllers run Windows Server 2008 R2. Contoso acquires a company named Tailspin Toys. Tailspin
Toys has a single Active Directory forest that contains a single domain. You need to configure the
DNS system in the Contoso forest to provide name resolution for resources in both forests. What
should you do?

A.
Configure client computers in the Contoso forest to use the Tailspin Toys DNS server as the
alternate DNS server.

B.
Create a new conditional forwarder and store it in Active Directory. Replicate the new conditional
forwarder to all DNS servers in the Contoso forest.

C.
Create a new application directory partition in the Contoso forest. Enlist the directory partition for
all DNS servers.

D.
Create a new host (A) record in the GlobalNames folder on one of the DNS servers in the Contoso
forest. Configure the host (A) record by using the Tailspin Toys domain name and the IP address of
the DNS server in the Tailspin Toys forest.
