Your full resource to successfully study for the Linux Foundation Certified System Administrator (LFCS) exam

Linux Foundation Certified System Administrator (LFCS) Complete Video Course, 3rd Edition is a comprehensive video training that will teach you core Linux concepts and usage along with clear explanations on the objectives of the LFCS exam. To offer this course in a way that is most efficient for you, the contents have been developed to build on your existing Linux knowledge. You will start with Linux Fundamentals, 2nd edition, a full video course on Linux basics, concepts, practices, and theories so you can get the foundational knowledge you need. You will then dive into the core part of the LFCS exam—including Advanced System Administration—and managing storage, security, SSH services, and virtualization. Each lesson ends with a lab for you to practice the skills learned in each lesson. These labs also act as training for the hands-on LFCS exam.

The LFCS section explores more advanced LFCS topics. It covers Advanced Systems Management; security; storage; containers and virtualization; and open-source solutions. The course then ends with a practice exam so you can test your skills, compare your answers to mine, and get a feel for the exam before you take the test.
