You work as an administrator at ABC.com. The ABC.com network consists of a single domain
named ABC.com. All servers in the ABC.com domain, including domain controllers, have Windows
Server 2012 installed.
You have installed the DNS Server Role on a ABC.com server, named ABC-SR13. ABC.coms
workstations make use of a web proxy to access the Internet, and refer to ABC-SR13 as a primary
DNS server.
You have been instructed to make sure that Internet host names for ABC.coms workstations are
not resolved by ABC-SR13.
Which of the following actions should you take?
A.
You should consider configuring a primary zone on ABC-SR13.
B.
You should consider configuring a secondary zone on ABC-SR13.
C.
You should consider configuring a reverse lookup zone on ABC-SR13.
D.
You should consider configuring a forward lookup zone on ABC-SR13.
deleting root hints or creating a “.” zone would work
Why is “D” not the correct answer here?.
Presumably the ABC-SRV13 has the web proxy set up as it’s DNS servers? So setting up a primary zone would be all that’s necessary? Any queries for Internet hosts would have to be passed through the SR13 to the web proxy and out to the Internet. This question is vexing.
You create a standalone primary zone and disable automatic updates. You manually put in the records you like to get resolved. //Sascha
D is CORRECT. It means that ABC-SRV13 will FORWARD to another DNS NOT resolving by itself.
D is Correct.. Creating a “.” Forward lookup zone. It prevents Internal Hosts to resolved Public DNS hostnames.

that is not one of the answers
If you dont know clearly, then please dont make others confused. let them know that you are not a hundred percent sure.
A is correct
Because on the DNS Administration Tool, the type of zone you have to create is a PRIMARY ZONE, this one is hosted UNDER the FORWARD LOOKUP ZONE….
because you see the zone created under forward lookup zone, it does NOT mean this is the zone type…
If you follow the wizard and try to create a new zone, you will see that there is NO forward lookup zone type to créate, JUST PRIMARY SECONDARY OF STUBs.
A is correct
Notice what the question asks: “make sure that Internet host names for ABC.coms workstations are not resolved by ABC-SR13”.
It clearly states ONLY “not to be resolved by ABC-SR13” and doesn’t say “to be resolved by the other dns servers”. So dns server must block the queries for internet domains. It can be done using the root zone in the dns manager.
For all those saying D, Forward lookup zones only translates DNS name to IP resolution which is further divided in 3 zones as stated by Emmanuel and on the contrary is reverse lookup zone that performs IP to name translation. So, A is the answer you are seeking.
99% sure A is the answer.
The question states that the server SR-13 should not resolve internet host names. It is a new dns server which means we can assume it has nothing configured yet. So we can configure SR13’s primary zone with external forwarders to resolve internet host names.
Answer A – If you right click the Primary zone icon (usually the name of the server) in DNS Manager, you configure the Forwarders in the Forwarders tab to your ISP DNS servers, all outside requests will get forwarded and resolved by external DNS servers and not SR13.
Answer B – Secondary zone is really a load-balanced zone for primary zones…
Answer C – Reverse lookup has nothing to do with the question.
Answer D – Forward lookup zone is for resolving internal devices (or external if other zones are created). BY configuring any forward lookup zones, means SR13 will resolve that query for you, which is opposite what the question asks.
I hope this clears things up for people.
