You have a DNS server named Server1 that runs Windows Server 2012 R2.
You need to disable recursion on Server1.
What are three possible ways to achieve the goal? Each correct answer presents a complete solution.

A.
From DNS Manager, modify the Advanced properties of Server1.

B.
Create a forward lookup zone named GlobalNames.

C.
From DNS Manager, modify the Forwarders properties of server1.

D.
Create a reverse lookup zone named 0.in-addr.arpa.

E.
Create a forward lookup zone named “.”.

F.
Run dns.cmd.exe and specify the /config parameter.

Explanation:
A: To disable recursion on the DNS server using the Windows interface
1. Open DNS Manager.
2. In the console tree, right-click the applicable DNS server, then click Properties.
3. Click the Advanced tab.
4. In Server options, select the Disable recursion check box, and then click OK.
E: Disable recursion on DNS servers that do not respond to DNS clients directly and that are not configured
with forwarders. A DNS server requires recursion only if it responds to recursive queries from DNS clients or if it
is configured with a forwarder. DNS servers use iterative queries to communicate with each other.
The DNS server has root DNS servers in its configuration so it returns the root DNS server details each time it
is queried for a non existent domain name. To prevent this we need to create a forward lookup zone with the
name “.”
F: To disable recursion on the DNS server using a command line
1. Open a command prompt.
2. Type the following command, and then press ENTER:
dnscmd <ServerName> /Config /NoRecursion {1|0}
