Your network contains an Active Directory domain named contoso.com. The domain contains a DHCP server named Server1 that 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 the DHCP console, reconcile Scope1.
B . From the DHCP console, delete Scope1.
C . From the DHCP console, modify the Scope Options of Scope1.
D . From Windows PowerShell, run the Set-DhcpServerv4Scope cmdlet.
Answer: B
Explanation:
You cannot change the subnet mask of a DHCP scope without deleting the scope and recreating it with the new subnet mask.
Set-DhcpServerv4Scope does not include a parameter for the subnet mask.
