You have a DHCP server named Server1 that runs Windows Server 2012 R2.
Server1 has two scopes named Production and Development. Currently, all DHCP clients register
their host name in a DNS zone named contoso.com.
You need to ensure that only the clients that obtain an IP address from the Development scope,
register their host name in a DNS zone named dev.contoso.com.
What should you do?

A.
Run the Set-DHCPServerv4Binding cmdlet.

B.
Modify the Advanced settings of the Development scope.

C.
Modify the Advanced settings of the DHCP server.

D.
Create a DHCP policy for the Development scope.

Explanation:
DHCP policies can be defined server wide or for a specific scope. Any DNS registration behavior of
the DHCP server which can be configured server wide or on a per scope basis – for example, turn
on/off the DNS registration (and deregistration) or DNS name protection – can be configured on a
per policy basis. DHCP Policies in Windows Server 2012
