Your company has a main office and two branch offices. The main office is located in London. The branch offices are located in New York and Paris.
Your network consists of an Active Directory forest that contains three domains named contoso.com, paris.contoso.com, and newyork.contoso.com. All domain controllers run Windows Server 2008 R2 and have the DNS Server server role installed.
The domain controllers for contoso.com are located in the London office. The domain controllers for paris.contoso.com are located in the Paris office. The domain controllers for newyork.contoso.com are located in the New York office.
A domain controller in the contoso.com domain has a standard primary DNS zone for contoso.com. A domain controller in the paris.contoso.com domain has a standard primary DNS zone for paris.contoso.com. A domain controller in the newyork.contoso.com domain has a standard primary DNS zone for newyork.contoso.com.
You need to plan a name resolution strategy for the Paris office that meets the following requirements:
If a WAN link fails, clients must be able to resolve hostnames for contoso.com.
If a WAN link fails, clients must be able to resolve hostnames for newyork.contoso.com.
The DNS servers in Paris must be updated when new authoritative DNS servers are added to newyork.contoso.com.
What should you include in your plan?
A. Configure conditional forwarding for contoso.com. Configure conditional forwarding for newyork.contoso.com.
B. Create a standard secondary zone for contoso.com. Create a standard secondary zone for newyork.contoso.com.
C. Convert the standard zone into an Active Directory-integrated zone. Add all DNS servers in the forest to the root hints list.
D. Create an Active Directory-integrated stub zone for contoso.com. Create an Active Directory-integrated stub zone for newyork.contoso.com.
