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. The exam is independent of distribution-specific tasks, therefore selecting a platform in the exam preparation checklist is no longer required.
