About LPIC Exam
https://www.lpi.org
Unlike M$, Cisco exams, LPIC exam do NOT have any dumps or even single focused study guides. It is not narrowed down towards any single Distribution either. You need to try out various distributions including Ubuntu, Fedora, Mandrake, Debian, etc. If you got RHEL DVD then go for it as well.
There are a plenty of resources out there in the Internet. Searching for LPIC Dumps or some other relative keyword may bring you a million links. Yet, LPIC have revised their exam this April 2009 and hence they all may seem 60-70 percent outdated. I have done a search for it last night and collected these resources from various forums, blogs and websites. If you are preparing for the latest LPIC certification exams, you should do ok with the below resources.

Linux + vs LPIC Certifications
Just a word of advice rather suggestion I would like to give is – If you are in a dilemma on whether to do Linux+ or LPIC then my move will be towards LPIC. LPIC ($150 for 101 exam and $150 102 exam) costs the same as Linux + ($300). CompTIA may sound familiar but then most of their certifications like Security+, Network+ are not considered very seriously. They however might be an add-on for you resume if you are a total fresher.
Good luck!
