hello all.. just want to ask u all a little question that i just cant figure
out why thats the answer for the question. i have just started studying for
70-210 and dont have much idea about subnetting.

this is the questions

You are the network adming of a company consisting of 100 client computers
and six subnets. you configure the first two subnets and conguire the first
two subnets and client computers on both subnets for testing. you test the
intial configuration and discover that not all of the client computers can
communicate with each other

The client computers in subnet 1 are named as Computer1 and Computer2

Computer 1 - IP - 131.107.5.198
Mask - 255.255.255.248
Gateway - 131.107.5.193

Computer 1 - IP - 131.107.5.195
Mask - 255.255.255.248
Gateway - 131.107.5.193


The client computers in subnet 2 are named as Computer3 and Computer4

Computer 3 - IP - 131.107.5.206
Mask - 255.255.255.248
Gateway - 131.107.5.214

Computer 4 - IP - 131.107.5.213
Mask - 255.255.255.248
Gateway - 131.107.5.213

Both Subnets are connected via router

Gateway 1 for Subnet 1 IP - 131.107.5.193
Mask - 255.255.255.248
Gateway 2 for Subnet 2 IP - 131.107.5.207
Mask - 255.255.255.248

A. Change the subnet mask of all client computers and on the two gateways to
255.255.255.240

B. Change the subnet mask of all client computers and on the two gateways to
255.255.255.255

C. Change the IP address for Gateway2 to 131.107.5.214 and the IP address
for Computer3 to 131.107.5.210

D. Change the IP address for Computer1 to 131.107.5.190 and the IP address
for Computer2 to 131.107.5.191


The correct answer is C

The one reason is we need make the default gateway used by computer 3 & 4 to
match the Gateway2. I understand this part.

The second reason is coz the IP Address of Comp3 belongs to another subnet
than Comp4 and Gateway2. So thats the reason we need to adgust the ip
address of comp3.

This is the part i dont understand. Any explanations will be much
appreciated!

Thanks a lot for spending time to read this far
