Installing and Configuring Windows Server 2012 — Question 10

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?

Answer options

• 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.

Correct answer: C

Explanation

The correct action is to run the Remove-DhcpServerv4Scope cmdlet, which deletes the existing scope that cannot be modified to have a different subnet mask. The other options either modify settings that are not applicable to changing the subnet mask or do not address the need to first remove the scope before creating a new one with the desired subnet mask.
