Linux Foundation Certified System Administrator (LFCS) 

The LFCS exam (and LFCS-JP) have been updated as of

May 11, 2023.

The LFCS exam was updated on May 11, 2023 at 00:00 UTC as part of our ongoing efforts to ensure that a Linux Foundation Certified System Administrator can proficiently install, configure, and operate Linux-based systems, whether on-premises or cloud-based.

What changed on May 11, 2023?

  • The LF is committed to making our exams distribution agnostic, and our new LFCS exam content is independent of distribution-specific tasks, therefore selecting a platform in the exam preparation checklist is no longer be required.
  • Any LFCS exam taken after 12:01am UTC on May 11, 2023 (including retakes), will test on the upcoming set of Domains and Competencies.

NOTE: It does NOT matter if the exam reservation happens to be for a first attempt or a retake, nor does it matter on what date you completed the exam purchase.  The only date that matters is the date you sit for the exam.
