Your network contains an Active Directory domain named contoso.com. The DNS zone for
contoso.com is Active-Directory integrated.
The domain contains 500 client computers. There are an additional 20 computers in a workgroup.
You discover that every client computer on the network can add its record to the contoso.com zone.
You need to ensure that only the client computers in the Active Directory domain can register
records in the contoso.com zone.
What should you do?
A.
Sign the contoso.com zone by using DNSSEC.
B.
Configure the Dynamic updates settings of the contoso.com zone.
C.
Configure the Security settings of the contoso.com zone.
D.
Move the contoso.com zone to a domain controller that is configured as a DNS server.
B
Isn’t D is the correct answer??
No! It’s Active Directory Integrated, so that means it’s already on a DC with the DNS Role enabled.
this is D
No it’s B
You will need to set it to secure dynamic updates, this way you will prevent any computer outside the domain to register any records

May be unclear, but , zone is already in.
Just Dynamic update is missing.
B
Secure Dynamic updates
