Your company consists of a single Active Directory forest with three domains.

Your company consists of a single Active Directory forest with three domains. The forest root domain is named contoso.com. There are two child domains named north.contoso.com and south.contoso.com. All servers run Server 2012 R2.

DNS1 is a DNS server that hosts a primary zone for contoso.com. DNSNorth is a DNS server that hosts a primary zone for north.contoso.com and DNSSouth is a DNS server that hosts a primary zone for south.contoso.com. The zones are not Active Directory integrated.

All computers in south.contoso.com are configured to use DNSSouth as their preferred DNS server. You need to make sure that all computers in south.contoso.com can resolve names in all three of the forest domains as quickly as possible. When a client in south.contoso.com submits a query to DNSSouth for a name in contoso.com or north.contoso.com, the query must be resolved correctly, even if the name being queried was changed a few seconds before. The name resolution process for queries for names that are outside the contoso forest should not be affected by your solution.

What should you do on DNSSouth? (Choose two. Each answer represents a part of the complete solution.)

A. Create a server level forwarder to the IP address of DNSNorth.

B. Create a server level forwarder to the IP address of DNSSouth.

C. Configure conditional forwarding for the contoso.com domain.

D. Configure conditional forwarding for the north.contoso.com domain.

E. Create a delegation for the north.contoso.com domain.

F. Add an A record for DNS1 and add an A record for DNSNorth.

G. Create a delegation for the contoso.com domain.

H. Add an NS record for DNS1 and add an NS record for DNSNorth
