| 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

| If you look at those IP's in binary you will get the point.
I suggest you search the net for subnetting in order to obtain further in
depth information on the subject.
Here are the IPs in Binary:
131.107.5.206
10000011.01101011.00000101.11001110
11111111.11111111.11111111.11111000
131.107.5.213
10000011.01101011.00000101.11010101
11111111.11111111.11111111.11111000
131.107.5.198
10000011.01101011.00000101.11000110
11111111.11111111.11111111.11111000
131.107.5.195
10000011.01101011.00000101.11000011
11111111.11111111.11111111.11111000
As you can see the network ID of PC 3 is not the same as on the other PCs

| hey.. are you saying PC3 should have
131.107.5.210
which in turn in binary is
10000011.01101011.00000101.11010010
11111111.11111111.11111111.11111000
and PC4
131.107.5.213
10000011.01101011.00000101.11010101
11111111.11111111.11111111.11111000
so they both have 1101 as their ID?
i just want to make sure whether i understood it right!
thanks

| all answers incorrect?
is it because of the subnet mask address - 255.255.255.248 ?!?
coz it gives you enough network IDs, but does not give you enough host IDs
that u need for the entire network?!?
is that why u r saying it is incorrect?!

| Because the question is irrelevant. Very unlike a real world scenario and even further from a Microsoft one. |
