HOTSPOT
Your network contains an Active Directory domain named contoso.com. The network
contains a DHCP server named DHCP1.
You add a new network segment to the network.
On the new network segment, you deploy a new server named Server1 that runs Windows Server 2012 R2.
You need to configure Server1 as a DHCP Relay Agent.
Which server role should you install on Server1?
To answer, select the appropriate role in the answer area.
Answer: 
Explanation:
In Windows Server 2012 R2 the DirectAccess feature and the RRAS role service were
combined into a new unified server role. This new Remote Access server role allows for
centralized administration, configuration, and monitoring of both DirectAccess and VPNbased remote access services. Additionally, Windows Server 2012 R2 DirectAccess
provided multiple updates and improvements to address deployment blockers and provide
simplified management.

The kicker in this question is to configure Server 1 as a “DHCP Relay Agent”.
Be careful of the Operative word(s) in the test questions. Some of the questions are simple but if you rush through them, you can end up choosing the wrong answer.
DHCP Relay Agent is configured through the Routing and Remote Access Service (RRAS) as you are routing DHCP traffic to a different subnet. It’s annoying how they call it ‘remote access’ now, seems a little misleading when you’re trying to get routing.
