20+ practice questions focused on Administrative Tasks — one of the most tested topics on the Linux Professional Institute Certification Level 1 LPIC-1 exam. Each question includes a detailed explanation so you learn why the right answer is correct.
Start Administrative Tasks PracticeA user reports that a cron job is not executing. The cron job is defined in /etc/crontab. The administrator checks the system logs and finds no errors. Which command should the administrator use to verify that the cron daemon is running?
Explanation: `pgrep cron` searches the process table for processes named 'cron' and returns the PID(s) if running. This is a quick, reliable way to verify the cron daemon is active without parsing full process lists or relying on systemd-specific commands.
A system administrator wants to schedule a script to run every Monday at 3:00 AM, but only if the system clock is set to local time (not UTC). Which crontab entry should be used?
Explanation: The crontab format is 'minute hour day-of-month month day-of-week command'. To run at 3:00 AM Monday, the minute field is 0, the hour field is 3 (using 24-hour time), and the day-of-week field is 1 (Monday). The cron daemon does not care about UTC vs local time; it uses the system's configured timezone, so no special flag is needed.
A Linux system fails to boot with the error 'Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0)'. Which of the following is the most likely cause?
Explanation: The error 'VFS: Unable to mount root fs on unknown-block(0,0)' indicates that the kernel cannot find or access the root filesystem. This typically occurs when the kernel lacks the necessary driver (module) for the storage controller (e.g., SATA, SCSI, NVMe) that the root device is connected to. Without the driver, the kernel cannot communicate with the storage hardware, resulting in the unknown-block(0,0) identifier.
Which THREE of the following statements are true about the /etc/shadow file?
Explanation: Option B is correct because /etc/shadow stores password aging data in fields 3 through 8 (last change, min, max, warn, inactive, and expire), which control password expiration. Option C is correct because /etc/shadow is normally owned by root:shadow with permissions 000 or 640, so only root (and members of the shadow group where applicable) can read it. Option D is correct because the second colon-separated field holds the encrypted password hash (for example, a $6$ SHA-512 crypt string), or a locked marker such as ! or * when no password is set. Option A is not correct as stated because it describes the second field of /etc/passwd being replaced by 'x' to redirect lookups to /etc/shadow, not the content of /etc/shadow itself. Option E is not correct because /etc/shadow is deliberately not world-readable; making it world-readable would expose password hashes to offline cracking.
Match each Linux signal to its default action.
Explanation: Common Linux signals: SIGINT, SIGTERM, and SIGKILL terminate processes; SIGSTOP and SIGTSTP stop processes; SIGQUIT terminates with a core dump.

2. Review every explanation
For each question — right or wrong — read the full explanation. Understanding why an answer is correct is more valuable than knowing the answer itself.
3. Focus on exam traps
Administrative Tasks questions on the LPIC-1 frequently use trap wording. Look for subtle differences in answers that test your precision, not just general knowledge.
4. Reach 80% consistently
Do repeated sessions until you score 80%+ three times in a row. Then move to mixed-mode practice to test cross-topic recall under realistic conditions.
