Linux Foundation Certified System Administrator (LFCS)


Credential: Linux Foundation Certified System Administrator (LFCS)  GI Bill resource
Credentialing Agency: Linux Foundation

Renewal Period: 3 years

The Linux Foundation Certified System Administrator (LFCS) certification is ideal for candidates early in their Linux system administration or open source career. The exam consists of performance-based items that simulate on-the-job tasks and scenarios faced by sysadmins in the real world. Obtaining certification allows individuals to validate their skills to prospective employers, which is particularly valuable if you have little on-the-job experience. There are no pre-requisites for this exam. Candidates must pass an online, proctored, performance-based exam that requires solving multiple issues from a command line running Linux.

More information can be found on the certifying agency's website.
