course

LPIC-1 is the first certification in LPI’s multi-level Linux professional certification program. The LPIC-1 will validate the candidate's ability to perform maintenance tasks on the command line, install and configure a computer running Linux and configure basic networking.

The LPIC-1 is designed to reflect current research and validate a candidate's proficiency in real world system administration. The objectives are tied to real-world job skills, which we determine through job task analysis surveying during exam development.

Current Version: 4.0 (Exam codes 101-400 and 102-400)

Prerequisites: There are no prerequisites for this certification

Requirements: Passing exams 101 and 102

Validity Period: 5 years

It is intended for aspiring system and network administrators, or anyone else who wants to learn the nuts and bolts of Linux. The course features extensive Linux simulations. You learn by doing, gaining valuable hands-on experience as you work to get a Linux server up and running. The skills you gain can be directly applied in enterprise computing environments.

The course also maps directly to the LPI Linux 101 exam objectives, so you can easily monitor your progress and your exam preparation status. .

  • Learn basic open source concepts.
  • Understand how Linux is used and the basics of the command line.
  • Apply skills using Linux virtual machine with step-by-step and hands-on lab activities.
