CCNA, CCDA, CCNP, CCDP, CCIP, CCVP and CCIE
Hi Fernando,I recommend that you focuss on this list: http://www.cisco.com/web/learning/le3/c ... ist.htmlIt lists over 30 books. Most of these I think are from Cisco Press. What you are finding is that the list on the Cisco Press web site http://www.ciscopress.com/markets/detail.asp?st=44718 does not match the more comprehensive list on the Cisco learning web site I would not buy the recommended R&S booklist as well. The risk is that you will end up studying for two different exams at once. You will find that that some of the books recommended are also used as part of the CCNP Security track.For example you will find books from the IPS and firewalling exams are also recommended for CCIE Security. If you listen to the TAC podcast I mentioned above the presenters recommend that you read widely including things like RFCs and looking for other security related books from other publishers. This will help you to cover each topic in depth.
