The LPI certification is a vendor-neutral Linux credential that measures critical Linux system and Network administration skills. LPI prides itself on delivering statistically valid exams and provides a quality testing experience for candidates around the globe. The LPIC Level II certification consists of two exams, LPI 201 and LPI 202. This 5-day course focuses on the LPI 201 exam and addresses the following knowledge areas:

• The Linux kernel
• System boot and shutdown
• File systems
• Hardware
• File and service sharing
• System maintenance
• System customization and automation

Target audience

This course is designed for students with 2 - 3 years of Linux experience that are interested in passing the LPI 201 exam. LPI Level I certification is recommended but not required
