Linux Foundation Certified System Administrator (LFCS)

LFCS was developed by The Linux Foundation to help meet the increasing demand for Linux administration talent. The exam consists of performance-based items that simulate on-the-job tasks and scenarios faced by sysadmins in the real world. Candidates can select either Ubuntu 18 or CentOS 7. Certified Linux systems administrators can work proficiently to design, install, configure, and manage a system installation. They will have an understanding of key concepts such as networking, storage, security, maintenance, logging and monitoring, application lifecycle, troubleshooting, API object primitives and the ability to establish basic use-cases for end users.
 

LFCS is ideal for candidates early in their Linux system administration or open source career. Candidates should have completed training in Linux system administration.
