Your network contains a Routing and Remote Access server named RRAS1 and a DHCP server named
DHCP1. RRAS1 and DHCP1 are located in different subnets. RRAS1 is configured to support VPN
connections from the Internet. DHCP1 has a scope that provides IP addresses for the VPN
connections. You need to ensure that VPN clients that connect to RRAS1 can receive IP addresses
from DHCP1. What should you do?
A.
On DHCP1, configure a DHCP Relay Agent.
B.
On DHCP1, install the Routing role service.
C.
On RRAS1, configure a DHCP Relay Agent.
D.
On RRAS1, install the Routing role service.
Explanation:
If a DHCP server is on the same subnet as your remote access/VPN server, DHCP messages from VPN
clients will be able to reach the DHCP server after the VPN connection is established. If a DHCP
server is on a different subnet than your remote access/VPN server, make sure that the router
between subnets can relay DHCP messages between clients and the server. If your router is running
a Windows Server 2003 operating system, you can configure the DHCP Relay Agent service on the
router to forward DHCP messages between subnets.
To configure the DHCP Relay Agent to work over remote access:
Click Start, point to Programs, point to Administrative Tools, and then click Routing and Remote
Access.
In the object tree, expand Your_Server, expand IP Routing, right-click General, and then click New
Routing Protocol.
In the Routing Protocols list, click DHCP Relay Agent, and then click OK.
Right-click DHCP Relay Agent, and then click Properties.
In the DHCP Relay Agent Properties dialog box, type the IP addresses of your DHCP servers in the
Server Address box, click ADD, and then click OK.
Right-click DHCP Relay Agent, and then click New Interface.
Click Internal.
Internal represents the virtual interface that is connected to all remote access clients.
