You havea dns server named server1 that runs Windows Server 2012 R2.
You need to disable recursion on Server1
What are three possible ways to achive the goal? Each correct answer presents a complete
solution.
A.
Create a reverse lookup zone named 0.in-addr.arpa.
B.
Create a forward lookup zone named globalnames
C.
From dns manager,modify the advanced properties of server1
D.
From dns manager,modify the forwarders properties of server1
E.
Create a forward lookup zones named “”
F.
Run dnscmd.exe and specify the /config parameter
1)modify the advanced properties of server1 –> dnsserver-properties-advanced-disable recursion
2)dnscmd.exe /config
3)???
Any ideas?
Answer is C, D and F. D – Disable root hints on forwarders tab.

If you do not want the server to use recursion, then clear the Use root hints if no forwarders are available checkbox.
Agreed, in the forwarders tab you can delete your forwarders AND disable your root hints. Creating the “.” forward lookup zone only achieves half that goal.
Ok, so we agree that C and F are correct answers based on this article: https://technet.microsoft.com/en-us/library/cc771738.aspx.
But i’m unsure about the last answer, because let’s assume that the person who typed the answer forgot to type the dot in “.”. That would make answer E correct.
Also, answer D would solve the problem by clearing the “Use root hints if no forwarders are available checkbox”, but for that option to be available you would need to have an IP address defined on that tab, otherwise that option wouldn’t even be available.
So i’m undecided here about the last answer, but i think i’ll have to wait for the question in the real exam. If answer E has no dot, like it hasn’t here, then i’ll choose D, otherwise i think i’ll stick with E.
Also, the link you posted ( https://technet.microsoft.com/en-us/library/ff807391(v=ws.10).aspx ) mentions this:
“If recursion is enabled then either root hints or forwarders must be configured.
If the Use root hints if no forwarders are available checkbox is cleared, then forwarders must be configured to resolve DNS queries for external zones. If the Use root hints if no forwarders are available checkbox is enabled, then root hints must be configured to permit recursion when forwarders are not responding.”
By default, forwarders tab isn’t configured with an IP address, which means that the checkbox on the “Use root hints if no forwarders are available” is enabled, and according to that microsoft’s statement above, you won’t be able to disable it unless you define an IP address as a forwarder, and that wouldn’t disable recursion. Which makes me think that the real exam will have a dot on the “”, making answer E correct.
Please correct me if i’m wrong.
zone “.” dot missing here
Tested in my lab and it is not possible to create a forward lookup zone name with “”. You will receive an error “The zone can not be created, The name is invalid”.
Answer = C,D,F
Please stop spamming wrong answers. You CAN create a FLZ named “.” and it even names it “. (root)”.
The other answers are “Advanced properties > disable recursion” and dnscmd /config /norecursion
C E F
you misread his email, he didn’t say “.” he said “”
One problem with working in IT is that you run into people who do some reading or an exam or 2 and decide they’re gods. They they decide that they’re entitled to belittle people who haven’t done that reading, or that exam.
answer is C, D, F

Answer is correct, only who typed the question forgot the ‘ .’
