Your company has a main office and two branch offices. The network contains one Active Directory
domain named contoso.com. All domain controllers and DNS servers for the contoso.com domain
are located in the main office. All DNS servers are member servers. You plan to deploy two new
Active Directory domains named east.contoso.com and west.contoso.com in the branch offices. You
install a DNS server in each branch office. You need to prepare the environment for the installation
of the new domains. What should you do next?
A.
Create a new standard primary zone on each branch office DNS server for the new domains.
Configure forwarders on the main office DNS servers to point to the branch office servers.
B.
Create a new stub zone on each branch office DNS server for the new domains. Configure
conditional forwarders on the main office DNS servers to point to the branch office DNS servers.
C.
Configure a delegation subdomain DNS record on the main office DNS server for each new
domain. Configure a stub zone on each branch office DNS server for the new domains. Configure
zone transfer for the contoso.com zone to the branch office DNS servers.
D.
Configure a delegation subdomain DNS record on the main office DNS server for each new
domain. Create a new standard primary zone on each branch office DNS server for the new domains.
Configure zone transfer for the contoso.com zone to the branch office DNS servers.
Explanation:
To deploy two new Active Directory domains in the branch offices, you need to first configure a
delegation subdomain DNS record on the main office DNS server for each new domain then create a
new standard primary zone on each branch office DNS server for the new domains and then
configure zone transfer for the Contoso.com zone to the branch office DNS servers after installing
DNS server in each branch office. In DNS, a subdomain is a portion of a domain that you’ve
delegated to another DNS zone. A subdomain is configured when you need to create domains in
existing domain. A company might use subdomains for its various divisions. Because, to migrate your
DNS zone data for the Contoso.com zone to the branch office DNS servers, you will need to have a
functioning standard primary server, you will need to create a new standard primary zone on each
branch office DNS server for the new domains.
