Well after passing my A+ last month its given me a huge boost in regards to getting on with it and passing another certfication, so after some consideration, I scanned through some stuff on the 70-271, and decided to book the exam for next month and knuckle down to some hardcore studying

Well the studying is going great, Ive done more studying these last two weeks, than well ive had hot dinners. and this is reflected in some practice exams ive done, hitting around 80% upwards.....But, the subnetting is driving me nuts.

I get what subnetting is for, and what it does, but when it comes down to working out the actual subnets, I just seem to confuse myself. I think one of my major problems is Ive read that much info about subnetting recently from different sources, that Im noticing conflictiing info, or the calculations seem to be done slightly differnet and well im getting brain overload.............headshot boom overload.

I think one of the problems is, im delving too much into the subject of Subnets, and not focusing on what I actually need to learn for the 70-271......

So my question is, Is there any type of area I should be specifically focusing on, Ive got a MS book and the CBT nuggets vid, but they seem to give a very brief view on subnetting, compared to other resources...

Any help would be greatly appreciated

To cut a very long explanation short - you won't need to be able to subnet for the 70-271.

Ahhhh .........I take it I just really need to be aware of it, and what it does.....

 

Yep.

 

Thankyou for the link, Think ill start scanning through it on my breaks, and return to the other areas of the MCP for my main studying, thanks to both of you for replying

 

I didn't like the CBT nuggets on subnetting to quick paces. have a look at this bloke mtasman on youtube Well explained.

try to memorise these 8 bits for subnet to get a mask address quick.

Ive got those masks in my head already the subnetting stuff has done wonders for for my Binary to Deciamal conversions as well. Cheers for the youtube link, ill have a gander at thome, as youtube is inside the "forbidden zone" at work..........

 

Not to detract, but this might be useful to you. All decial/hex/binary conversions can be done using Windows calculator, which you get in all Microsoft exams

Qs

 

I wondered if you got the calc in the exams. I can convert Binary into decimal and vice versa now and trying to keep the habit of not using a calc, however Id like brush up on the hex

Cheers for letting me know
