Subnetting Question Again!!!
I asked the question before and the answers that I have received stated that it was only necessary to have a understanding knowledge of what subnetting is and why it is needed. I am using both of the following books to study "Exam Prep 2" and "The Complete Guide to Networking and Network+". Both authors seem to stress the importance of learning how to subnet for the exam as it will be covered. Will I be asked a question on how to subnet a given address or do I just need to know what it is and why?

A search of that document lists sub-netting only once in section 2.7 which states.
2.7 Identify the purpose of subnetting.
I am sure there are FAQ's everywhere that say how to do this as it is the same for all tests from any cert agency Microsoft, Cisco, CompTIA etc. You can't expect to be tested if they don't tell you what you must know. You would be surprised how many ghost writers there are for authors whom may not even posses the cert that they are writing about. I read in a thread here that the bottom of the IT ladder was computer operator or cable b*tch. Below that are ghost writers.
Then, I think Microsoft should not be using the term "Network Infrastructure".
We have some MCSEs where I work, and they assure me that they had to learn everything there is to know about networks, except how to configure Cisco gear, for the MCSE exams. I have had my doubts for a long time.
Well, recently, there were 3 MCSEs trying to get a new printer to work, but couldn't. They told me that there was a network problem. The setting page out of the printer looked fine, and I could connect my laptop to the printer's switch port. It's not really my job to fix these things, but I thought I would help.
I waited until they move to their next problem, and I looked at the PC they had been using. The network address on the PC was completely wrong so I fixed it. Everything started coming out of the printer.
They demanded to know what I did so I told them. They got mad and told me that the IP address on the PC didn't matter. Any IP address should work. When I tried to explain that the PC had to have an address on the subnet to which the PC was attached, I was told that they were MCSEs which meant that they were network gurus, and I didn't know what I was talking about. They think I fixed the printer's switch port.
From all the exams I took with MS, none asked me about subnetting. They use classfull addresses to test you on routing.
If you want to know how to subnet, you should look into CCNA, where you will have a solid basic understanding of networking...
This is IMO...
But I got stuff from clients all the time. Clients that are supposed to be installing the stuff, since they are resellers. Basic routing they often didn't know.
