LFCA – Linux Foundation Certified IT Associate

The Linux Foundation Certified IT Associate (LFCA) is an entry-level certification for people starting careers in IT, cloud, and open-source environments. It covers Linux fundamentals, system administration basics, networking, security essentials, cloud concepts, DevOps principles, and the open-source ecosystem — without requiring prior professional experience. It is vendor-neutral, hands-on oriented, and designed as a foundation for more advanced certifications like the LFCS, CKA, or cloud-specific credentials. Ideal for career changers, students, and junior IT staff who want a broad, practical introduction to modern IT.
