LFCS Mock Exam I

Twenty state-graded tasks under the clock — no hints, no feedback until you submit. Weighted like the current LFCS: operations, networking, storage, essential commands, and users and groups, graded on what the machine says.

The rules — read them

120 minutes, 20 tasks, 66% to pass.
No hints, no verify. You won't know if a task passed until the end.
Graded on system state — reboot-persistence included, exactly like the real exam.
Advancing is final. Each task is graded and its box destroyed when you move on.
The clock does not stop. At zero, whatever's done is graded and scored.
Parity guarantee: these are the identical checks practice "Verify & grade" runs.
