Your network contains two Active Directory forests named contoso.com and corp.contoso.com.
User1 is a member of the DnsAdmins domain local group in contoso.com.
User1 attempts to create a conditional forwarder to corp.contoso.com but receive an error message
shown in the exhibit. (Click the Exhibit button.)
You need to configure bi-directional name resolution between the two forests.
What should you do first?
A.
Add User1 to the DnsUpdateProxy group.
B.
Configure the zone to be Active Directory-integrated.
C.
Enable the Advanced view from DNS Manager.
D.
Run the New Delegation Wizard.
Explanation:
The zone must be Active Directory-integrated.
Think the answer is D there – the error is probably caused by being the same namespace – which would make a forwarder not work. You have to delegate in that case. There’s an article here that explains it :

yep, watcher is right:

Actually no.
Answer is D.
Because you trying to create a forwarder for domain that uses same namespace.
A error in the exhibit must be
“zone configuration error: corp.contoso.com domain controllers are not authoritative for the corp.contoso.com domain”
So you have to use delegation instead of forwarding.
