I must admit that i'm usually reluctant writing reviews on other people's hard work, EXCEPT NOW!!!This book will help you FAIL your BCRAN!! No doubt.It's written in a format that gives you the confidence that it covers all aspects of the required exam. It doesn't!!I had to spend an hour or two in a bookshop reading the details and proper configuration explanantion of PPPoe.The book treats dialer-watch as non-existent!That's THREE exam questions!!Get my drift yet??There's also a very woolly explanation of queueing and compression!!.My knowlege and experience of Qos got me through.....3/4 questions!!Remeber, i'm no new kid on the block here...Over 9 year's experience....and still failed firsttime...by 80marks!!I resat the exam 6 working days later, having checked out the weak areas (not covered by this 'book'), and looking at exam cram and testking.I scored 930!!! something not right!!Good book for the shelf...that's about it!! sorry.Be warned.
