Hi there,

Currently studying for the 70-270 using the Sybex book and Test Out.

One thing I encountered in one of the testout exam sims was a question asking me to specify which IP addresses would be available on a network setup with a custom subnet.

I can find no mention of this in the Sybex book.
I have tried to learn about subnetting, have spend quite a lot of time on learntosubnet.com and watched through all the presentations. I have learnt a heck of a lot about TCP/IP, but still don't seem to be able to grasp subnetting.

Before I go completely mad and smash my head against the nearest wall, are there any on-line sources which explain the process in lay-man's terms?

More importantly, will I be required to learn about custom subnets and their effects on IP Address ranges for the exam?

Cheers

Jon

 

Also know why you may get a 169.254.xxx.xxx address.

 

You need to know the concepts of networking. You do not need to be able to do the math.

 

I seem to remember getting some kind of subnet question on the exam. Can't remember what it was but remember they were on different subnets and that made a difference to the answer.

I think Tinus has it about right, you need to know that the subnet mask is used to work out if another PC is on the same network and how this is done.

I got some practice exam questions asking how many IPs you'd get out of a certain subnet mask but I think this is more to enforce your comprehension of the subject as opposed to exam content.

 

I think you just need to know about Classful IP addressing and APIPA, not actually how to subnet.

I'm sure it mentions that in the MS Press book.

 

Agreed.

From memory, APIPA (for whatever use!) is covered, along with classful IP ranges. No mention of binary, masks etc on here.

 

on the 70-270 none of this is needed however on some of the exams APIPA and basic subnetting is required as the problems is DHCP and you can tell because one of the nodes is using 169.254.xxx.xx but you wont have to do any maths. there are a few questions on which exams i cant remember where you are asked to choose a subnet to accomodate a certain number of users.

thats such a badly constructure sentence...meh its 6am
