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.
