Really excited to share the news that on April 14th I got certified as a Linux Foundation Certified System Administrator, a certification offered from the Linux Foundation. This is an online, hands-on and practical exam that tests whether the candidate has the knowledge and experience to perform common tasks on a Linux server, in the following areas and weights:
- Essential Commands – 25%
- Operation of Running Systems – 20%
- User and Group Management – 10%
- Networking – 12%
- Service Configuration – 20%
- Storage Management – 13%
Certification is valid for two years, after that you have to renew. For more information regarding the exam format, the curriculum and recommended ways to study check the official LFCS page here as well as the official handbook and certification preparation guide. Personally, I used a Centos Azure Virtual Machine as well as Windows Subsystem for Linux as environments where I could practice the various commands (you really need to do a lot or practice, as the time during the exam is really limited). I also watched the excellent course “Linux Foundation Certified System Administrator” from Sander van Vugt which really brought my up to speed with the exam’s requirements as well as freshened up my Linux skills. You are also encouraged to practice using vi (basic stuff in navigation and editing was enough for me) as well as learning to efficiently use man pages. If you’re planning to take the exam, you should practice, practice and practice, best of luck!
