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.
“You need to ensure that Server1 !forwards all queries! for ad.contoso.com to Server2.”
In that case you should create the conditianal forwarder for ad.contoso.com to point on Server2.
Answer is B.
And the D is works. I am puzzeled.
Zone delegation as ad.contoso.com is a subdomain name of contoso.com. if it was a different root level domain then a conditional forwarder would be right.
Yes, the answer is B
blah blah “forwards” all queries blah blah.
That’s the keyword here, “forward”. Conditional forwarder does exactly that.
“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.”

So it seems like B is right, however zone delegation works as well. I’ve done so much Google searching in the past 30 minutes and both of these answers are so similar.
