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

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 recursionon DNS servers that do not respond to DNS clients directly and that are not
configured with forwarders.A DNS server requires recursiononly 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 configurationso it returns the root DNS server details
each time it is queried for a non existent domain name. Toprevent this we need to create a forward
lookup zone with the name “.”
F: Todisable recursionon 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} Disable Recursionon the DNS Server
