Explanation:
If you opt to create a centralized or hybrid DHCP infrastructure, you will need a DHCP relay agent on every
subnet that does not have a DHCP server on it. Many routers are capable of functioning as DHCP relay agents,
but in situations where they are not, you can configure a Windows Server 2012 computer to function as a relay
agent.
In Windows Server 2012 R2 the DirectAccess feature and the RRAS role service were combined into a newunified server role. This new Remote Access server role allows for centralized administration, configuration,
and monitoring of both DirectAccess and VPN-based remote access services. Additionally, Windows Server
2012 R2 DirectAccess provided multiple updates and improvements to address deployment blockers and
provide simplified management.
