You are the Exchange administrator for you company. The relevant portion of the network is configured in the follow Diagram.
The network serves two offices, one in London and one in Paris. Each office contains a single Exchange Server 2003 computer in its own routing group.
The routing groups are connected by a routing group connector.
The only network traffic between the two offices is e-mail messages. There is a permanent WAN link that connects the two offices. The WAN link is connected to a hardware router in each office.
The two hardware routers each also have an ISDN dial-up interface. Demand-dial routing is defined between the two offices.
You view network utilization statistics in the Paris office, and you discover that traffic from the Paris Exchange server frequently causes the ISDN link to connect.
There is little utilization of the permanent WAN link between the two offices. The WAN link has been very reliable and has suffered no downtime.
You need to ensure that the ISDN link is used only when the permanent WAN link fails.
What should you do in the Paris office?
A.
Request the network administrator to remove the IP route that uses the ISDN Iink from the routers.
B.
Request the network administrator to reconfigure the routers, so that the IP route that uses the ISDN link is assigned a higher cost than
the permanent WAN link.
C.
Request the network administrator to reconfigure the routers, so that the IP route that uses the ISDN link is assigned a lower cost than
the permanent WAN link.
D.
On the Exchange server, create a TCP/1P static route to the London Exchange server.
E.
On the Exchange server, replace the routing group connector with an SMTP connector that uses the ETRN command.
F.
On the Exchange server, replace the routing group connector with an SMTP connector that uses the London Exchange server as a smart host.
Explanation:
When you assign a higher cost to a route, that route will only be used if the primary line fails.
