A roadmap for LPI-302

About this series

Linux Professional Institute Certification (LPIC) is like many other certifications in that different levels are offered, with each level requiring more knowledge and experience than the previous one. The LPI-302 exam is an elective specialty exam in the third level of the LPIC hierarchy and requires an advanced level of Linux system administration knowledge.

To get your LPIC level 3 (LPIC-3) certification, you must pass the two first-level exams (101 and 102), the two second-level exams (201 and 202), and the LPIC-3 core exam (301). After you have achieved this level, you can take the elective specialty exams. As of November 2010, these specialty exams are:

• 302. Mixed environments (the focus of this roadmap)
• 303. Security
• 304. Virtualization and high availability
• 306. Web and intranet (in development)
• 305. Mail and messaging (in development)

Passing any of these exams earns you the appropriate designation on top of your LPIC-3 credentials.

This series prepares you for the Mixed environment specialty exam, which focuses entirely on managing Linux clients and servers in a heterogeneous Linux and Microsoft environment. This is done almost entirely through the tools that the Samba project provides, so to pass the 302 exam, you must master the installation, configuration, and troubleshooting of Samba.

It is rare to find a large company that doesn't have some amount of Windows infrastructure, so this series will prove to be helpful even if you aren't planning to take the LPI-302 Mixed environments exam.
