I'm preparing for the LFCS exam and currently working through Mumshad's course and its practical exercises. I'm looking for additional hands-on labs that closely match the exam objectives. I know about Killer.sh, but its 36-hour access window isn't long enough for my study schedule. Are there any similar platforms, open-source labs, or GitHub repositories with useful LFCS practice exercises?

Hands-on practice is more valuable than simply adding another video course. Focus on completing tasks from the exam objectives in a terminal, and use lab environments or virtual machines to repeat them until the commands and troubleshooting steps become familiar.
Some learners have reported that parts of the course labs are broken or don’t always line up with the material. If you continue using it, verify the exercises against the current LFCS objectives and supplement it with independent lab practice rather than relying on the course alone.
I’ve noticed some broken labs too, but I still need the LFCS certification because my employer requires it.
Take a look at Linux DSOXLab Training. It’s a free, open-source lab environment with practical exercises that can help prepare you for both the LFCS and RHCSA exams.
This is exactly the kind of resource I was looking for. Thanks a lot!

That’s why I’m specifically looking for more hands-on practice sources.
