Your company has one office in San Diego and one office in New York.
The network consists of one Active Directory forest that contains one domain named contoso.com and one domain named newyork.contoso.com. All servers run Windows Server 2008. All domain controllers for contoso.com are located in San Diego. All domain controllers for newyork.contoso.com are located in New York.
Contoso.com contains two domain controllers named Server1 and Server2.
Newyork.contoso.com contains two domain controllers named Server3 and Server4. All domain controllers host Active Directory-integrated DNS zones for their respective domains.
You need to ensure that users from each office can resolve computer names for both domains from a local DNS server.
What should you do?
A. Add the contoso.com and the newyork.contoso.com DNS zones to the ForestDNSZones partition.
B. Create a stub DNS zone for contoso.com on Server3. Create a stub DNS zone for newyork.contoso.com on Server1.
C. Create a standard primary DNS zone named contoso.com on Server3. Create a standard primary DNS zone named newyork.contoso.com on Server1.
D. Configure conditional forwarders on Server1 to point to Server3. Configure conditional forwarders on Server3 to point to Server1.
Correct Answer: A
Explanation/Reference:
Explanation:
To ensure that users from each office can resolve computer names for both domains from a local DNS server, you need to add the contoso.com and the Branch.contoso.com DNS zones to the ForestDNSZones partition because the ForestDNSZones directory partition can be replicated among all domain controllers (DCs) located in both the domains Contoso.com and

Newyork.contoso.com in the forest of the company.
This is because all the domain controllers have the DNS service installed. Once the DNS Zones data is replicated the users from each office can resolve computer names for both domains from their local DNS server
A stub zone cannot be used because it is used to resolve names between separate DNS namespaces a Standard Primary DNS zone cannot be used because the DNS Server in this type of zone contains the only writable copy of the DNS zone database files. There can be only one Standard Primary DNS Server for a particular zone. A conditional forwarder cannot be used because it handles name resolution only for a specific domain.
