About This Certification

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.

The exam tests very practical skills that are useful in the day to day job. I am very impressed by how good the web terminal is, it feels just like a normal terminal emulator.
