Linux Professional Institute (LPI) offers three different certification tracks. The core certification program, Linux Professional, contains three different levels addressing distinct aspects of Linux system administration. The organization also offers an introductory Essentials program for beginners in Linux and open source, as well as an Open Technology track for professionals working with additional technologies such as DevOps and BSD.

This article will focus on the Linux Professional Certification Track.

Linux Professional Certification Track

The Linux Professional Certification Program consists of the LPIC-1, LPIC-2, and LPIC-3 Enterprise certifications.

LPIC-1 and LPIC-2 certifications are focusing on Linux System Administration. LPIC-3 level of certifications has several specialities: LPIC-3 Enterprise Security, LPIC-3 Enterprise Mixed Environments and LPIC-3 Enterprise Virtualization and High Availability

LPIC-1 and LPIC-2 certifications each require passing two exams, while each LPIC-3 level of certification requires passing a single exam.

Each exam has a series of topics that make up the exam objectives. Each objective has an associated weight that corresponds to the frequency of exam questions from that objective.
