3Delivering Continuously Available ApplicationsWindows Server 2012 R2 Preview||3Highly Available DHCP Service

Automatic DHCP failover based on DHCP failover IETF specProvides multi-site IP address continuity to clients by helping eliminate single points of failureProvides in-box support for failover, without the need for clustering Uses a failover setup consisting of two servers located across different geographic locationsIncludes active/active or active/passive behaviorSimple provisioning and configuration of DHCP server using PowerShell

4Hot standby DHCP failover in a hub-and-spoke deployment

Load-sharing DHCP failover in a single site with a single subnet
