About the LPIC-3 High Availability and Storage Clusters Exam

The LPIC-3 certification is the culmination of the multi-level professional certification program of the Linux Professional Institute (LPI). LPIC-3 is designed for the enterprise-level Linux professional and represents the highest level of professional, distribution-neutral Linux certification within the industry. Four separate LPIC-3 specialty certifications are available. Passing any one of the four exams will grant the LPIC-3 certification for that specialty. The LPIC-3 High Availability and Storage Clusters certification covers the administration of Linux systems enterprise-wide with an emphasis on high availability systems and storage.

Prerequisites

Candidates must have an active LPIC-2 certification before attempting the LPIC-3 exam.
