cheat sheets
Cheat Sheets are not really sheets to cheat with.
The naming is a little controversial but it’s the best name I can. Basically a cheat sheet is a document that has 1, 2 of even maybe 3 pages (sheets) with a lot of very important information grouped in 1 document that is focused on just 1 specific topic.
Jermy Strech created a lot of great cheat sheets on his website, and this is my example and motivation to create some of the cheat sheets with topics that can’t be found on Jermy’s packetlife.net website.
Below you will find all the sheets I created that helped me trough my study. All cheat sheets will be based on Cisco’s Voice Technology.
