The Linux Foundation's system-administration credential, built from community-identified competencies.
PERFORMANCE-BASED, which is why it is worth more than its price suggests: you do real tasks in a live environment for two hours rather than answering questions. Note the neighbouring LFCE exam was RETIRED in May 2022 — if you find it recommended anywhere, that advice is at least four years stale.
