Overview: Configure DHCP failover using the DHCP console
To configure DHCP failover using the DHCP console, right-click a DHCP scope or right-click IPv4 and then click Configure Failover.

The Configure Failover wizard guides you through configuring DHCP failover on the selected scope.
Note: The DHCP server failover feature, available in Windows Server 2012 and later, provides the ability to have two DHCP servers provide IP addresses and option configuration to the same subnet or scope, providing for continuous availability of DHCP service to clients.

D. Failover clustering is possibly, but would not minimize administration.
