Your network contains an Active Directory domain named contoso.com. The domain contains a DHCP server
named Server1that runs Windows Server 2012 R2.
You create a DHCP scope named Scope1. The scope has a start address of 192.168.1.10, an end address of
192.168.1.50, and a subnet mask of 255.255.255.192.
You need to ensure that Scope1 has a subnet mask of 255.255.255.0.
What should you do first?

A.
From Windows PowerShell, run the Remove-DhcpServerv4PolicyIPRange cmdlet.

B.
From the DHCP console, modify the Scope Options of Scope1.

C.
From Windows PowerShell, run the Remove-DhcpServerv4Scope cmdlet.

D.
From Windows PowerShell, run the Set-DhcpServerv4Scope cmdlet.

E.
From the DHCP console, modify the properties of Scope1.

F.
From Windows PowerShell, run the Set-DhcpServerv4Policy cmdlet.

Explanation:
Set-DhcpServerv4Scope sets the properties of an existing IPv4 scope on the Dynamic Host Configuration
Protocol (DHCP) server service.
