Your network contains an Active Directory domain named contoso.com.
The domain contains a server named Server1 that runs Windows Server 2012 R2 and has the DNS Server server role installed.
Server1 is configured to use a DNS server from an Internet Service Provider (ISP) as a forwarder.
Corporate management requires that client computers only resolve names of contoso.com computers.
You need to configure Server1 to resolve names in the contoso.com zone only.
What should you do on Server1?
A.
From DNS Manager, modify the root hints of Server1.
B.
From Windows PowerShell, run the Remove-DnsServerForwarder cmdlet.
C.
From Windows PowerShell, run the Set-NetDnsTransitionConfiguration cmdlet.
D.
From DNS Manager, modify the Advanced properties of Server1.
Explanation:
If the DNS server does not know the address of the requested site, then it will forward the request to another DNS server. In order to do so, the DNS server must
know of the IP address of another DNS server that it can forward the request to. This is the job of root hints. Root hints provides a list of IP addresses of DNS
servers that are considered to be authoritative at the root level of the DNS hierarchy(also known as root name server).
