Linux: LPI exam resources

I am compiling this list of resources for people wanting to get their LPI qualifications.

The Linux Professional Institute Inc. (LPI) is a non-profit organization that provides vendor-independent professional certification for Linux system administrators and programmers.

The Linux Professional Institute Certifications (LPIC) provide a qualification that can be used to indicate that someone is competent at a certain level.

Should you have any other resources please leave a comment.
