I just passed the Linux+ about 2 weeks ago, which is powerd by LPI. I originally took the 101 exam about 2 years ago and just got around to the 102. If you have not yet payed for the exam, pay for the CompTIA Linux+ exam, then make sure you select the box to send your info to LPI and you will get both certs. You can then also submit your info to Novell to get your Novell cert as well.
Anyways, I used a few things to study and help brush up on topics I dont use often, such as the graphical environments being I don't ever work with those.
If you would like some of the PDFs I found then send me a PM with your email and I'll send them over. I do not have any braindumps but do have some third party PDFs that may help you review some of the topics and are completely acceptable within the CompTIA and LPI policies if you use a Braindump you risk losing your cert.
For the most part though, they are pretty easy, just dont get yourself to over anxious. This is a fundamental style exam and with the exception of a few questions they are all multiple choice and if you have a year or two working with Linux you shoudl be able to reasonably identify the one based upon the syntax, etc.. You dont need to know all of the specific options. You just need to know for instance, that find and locate will help you find a file but search does not exist(this is not an actual exam question but they asked some a long these lines). Gotta be careful when approaching these as it could put both of our certs in jeopardy if I feed you the questions/answers.
