Does Lammle book contain false information?

Hi all,

I just finished to read the CISCO official exam study guide. I want to read through the Lammle book too.

But I read that it contains wrong information such as TCP is used for VoIP. But according to the Book I just finished, UDP is used for VoIP, which makes more sense anyways.

I know it now.. but if I'd read Lammle before the other book, I'd be quite confused now.

My question is, does Lammle contain lots of "false information"?

Thanks,

IMO, no. Lammle's books were great for me. I did a web search and found this thread which answers your question:

Great, looking forward to get the book now.

I read the book and feel it heavily contributed to my passing CCNA. Lammle does an excellent job of teaching you the facts AND keeping you interested. I met him too and he is a great guy!
