B. LINUX Professionals Institute Certification Cross-Reference
These requirements are quoted verbatim from the LPI web page <http://www.lpi.org/>.
For each objective, the relevant chapter or section from this book
is referenced in parentheses: these are my additions to the
text. In some cases, outside references are given. Note that
the LPI level 2 exams have not been finalized as of this writing.
However, the preliminary draft of the level 2 curricula is mostly
covered by this book.
Each objective is assigned a weighting value. The weights range roughly from 1 to 8, and indicate the relative importance of each objective. Objectives with higher weights will be covered by more exam questions.
