The ABC.com network consists of a single Active Directory domain named ABC.com. All servers
on the ABC.com network run Windows Server 2003 and all client computers run Windows XP
Professional. The domain consists of two IP subnets named ABCA and ABCB. A server named
ABC-SR20 has Routing and Remote Access enabled and currently connects ABCA and ABCB.
Each subnet has a DHCP server which is used to sign IP configurations to client computers on the
local subnet. All servers have static IP configurations.
The network layout is shown below:
You are preparing the provision of Internet connectivity by means of implementing a Microsoft
Internet Security and Acceleration (ISA) Server 2000 array on the network. The arrays internal IP
address is 172.35.60.1.
You configure ABC-SR10 to provide the 172.35.60.1 as the default gateway. ABC-SR11 provides
the IP address 172.28.60.1 as the default gateway for ABCB client computers. ABCB client
computers can access servers on ABCA successfully.
You received complaints from the ABCB users about an inability to access Internet-based
resources.
How can you ensure that the ABCB users can access the internet?
A.
By configuring ABC-SR11 in order to provide the address 172.35.60.1 as the default gateway.
B.
By moving the ISA server array to ABCB.
C.
By configuring 172.68.124.31 as the default gateway for ABC-SR20.
D.
By adding a default route to 172.35.60.1 on ABC-SR20.
E.
By configuring ABC-SR11 to provide 172.35.60.1 as a default route to the client computers.
Explanation:
The routing and remote access server knows how to route traffic between SubnetA
and SubnetB. However, it doesnt know how to route traffic to the internet. We can fix this by
adding a default route on ABC-SR20. The default route will tell ABC-SR20 that any traffic that isnt
destined for SubnetA or SubnetB (i.e. any external destination) should be forwarded to the internal
interface of the ISA server (172.35.60.1).
