Your network contains two servers named Served and Server 2. Both servers run Windows Server
2012 R2 and have the DNS Server server role installed.
On Server1, you create a standard primary zone named contoso.com.
You plan to create a standard primary zone for ad.contoso.com on Server2.
You need to ensure that Server1 forwards all queries for ad.contoso.com to Server2.
What should you do from Server1?
A.
Create a trust anchor named Server2.
B.
Create a conditional forward that points to Server2.
C.
Add Server2 as a name server.
D.
Create a zone delegation that points to Server2.
Explanation:
You can divide your Domain Name System (DNS) namespace into one or more zones. You can
delegate management of part of your namespace to another location or department in your
organization by delegating the management of the corresponding zone. For more information, see
Understanding Zone Delegation.
Isn’t the correct awnser B?
Create a conditional forward that points to Server2.

I`m for B too.

The main aspect is “a standard primary zone for ad.contoso.com”, so D is appropriate.

and how exactly will server1 “forward” queries for ad.contoso.com to server2 if the answer was D?

Zone delegation means any queries in regards to the desired domain zone (ad.contoso) outside of your domain (contoso.com) are sent to the defined server (server2) which handles that zone.
D.
B is wrong because a Conditional Forwarder is for forwarding DNS queries to a specific DNS server within your domain.

Not true.
The DNS server authoritative for microsoft.com can forward queries for DNS names that end with example.microsoft.com, if example.microsoft.com is delegated to another DNS server.

None of the articles I’ve found online state that conditional forwarder has to forward to a DNS server within or outside your domain. You can set it up to forward to any server, regardless if you host it or not.

Here’s a pretty good analogy I came up with, which may help explain which answer to choose here. Let’s say there are 3 people, named Bob, Joe and Mary.
Bob sends an email to Joe, the content looks something like this:
“hey Joe, can you please ask Mary to do XYZ for me? Thanks.”
Joe can either send a new email “to” Mary:
“Hey Mary, can you do XYZ for Bob?”
OR, Joe can “forward” Bob’s email to Mary.
The question here mentions the keyword “forward”.
Conditional forwarding literally forwards DNS queries to another DNS server. Zone delegation looks at the DNS query and delegates it instead. I know this may seem like it’s “forwarding” the request as well, but this is like one server “pointing” the client machine “to” somewhere else. To put it simply, if Bob asks Joe to hand a love letter to Mary for him, Joe could either point Bob to Mary’s office and tell him to do it himself, OR he could take Bob’s letter and forward it to Mary.

Delegation is delegating administration, SOA, etc, to a child portion of the namespace. The question did not ask for this. Most Microsoft questions asks you to either minimize administrative efforts or administrative permissions. So I think with this in mind, conditional forwarder is probably the best option here.

D appears to be the correct answer.
You are delegating a portion of your namespace (contoso.com) to another DNS server.

Conditional Forwarder would generally be used to forward to a separate namespace/domain.
I think both options would work, but I am not certain.
