Lenin's collected works, unabridged edition
on 8 February 2016
This book is the ccna BIBLE. Everything you can possibly need to learn for CCNA is in it. There are books that sometimes cover a topic superficially; this is not one of them.
* The scope of each topic is deeper than needed for the exam. If all you're after is passing the exam, this will slow you down with unnecessary detail.
* It is incredibly difficult to read. If I made a deliberate effort to make something incomprehensible, I still wouldn't write it half as badly as this. The writing style requires reading, rereading, questioning your sanity and rereading the page again. I suffered through 300 pages of ICND2 part before I gave up and bought the damn Sybex study guide.
* Low information density. This book can be condensed into half of its size without losing any information simply by using shorter simpler sentences, less repetition and fluff. If you use a highlighter, you'll sometimes go through 10 pages only to highlight 2-3 sentences on each. Get ready to flip pages. A lot.
It's a cure for insomnia. If you manage to read more than a couple of pages in one go and force yourself to stay awake, you will get to see a tiny piece of your sanity ride into the sunset on a unicorn.
