@JNat what do you mean with found? the questions are on the net, and so are the answers, you just need to memorize them, same as with a lot of cisco or other exams
if you want to "pass" easy , that is.
if you wonder however how the questions got to the net, i assume teachers are at least partially to blame, some questions are in the LPI test programs anyway, so i guess with just copy/pase or reverse engineering you get a lot of them already, and the rest is to be obtained by teachers or via the "certified training centers".
id go with the LPIC Certs if you need a cert. However this might be different in your country. For mine (.de) a lot of people i know who work as sysadmins have at least some LPI Certs.
the one you refering to reads to me as " stay in class for X days, get cert without actually proof of knowledge" , but i only glanced at the page.
