Reinforce LPIC-1 concepts with active-recall study cards covering all 7 blueprint domains. Each card shows the question on the front and the correct answer with a full explanation on the back.
Flashcards work through active recall — the process of retrieving information from memory rather than passively re-reading it. Research consistently shows that active recall produces stronger, longer-lasting memory than re-reading study guides. For LPIC-1 preparation, this means flashcards are one of the highest-return study tools available.
Attempt recall first
Read the LPIC-1 question on each card, pause, and attempt to formulate the answer in your own words before revealing. This retrieval attempt — even if wrong — dramatically strengthens memory compared to immediately reading the answer.
Review wrong cards again
When you get a card wrong, note it and add it back to your review pile. Spaced repetition — seeing difficult cards more frequently — is the mechanism that makes flashcard study far more efficient than linear reading.
Study by domain
Group your LPIC-1 flashcard sessions by domain for the first 3–4 weeks. Master one domain before moving to the next. In the final week, shuffle all cards together to test cross-domain recall — which is what the real LPIC-1 exam requires.
Short sessions beat marathon reviews
20–30 flashcard cards per session, done daily, produces better retention than a single 200-card marathon session. Five short daily sessions per week over 4 weeks gives you over 400 total card reviews — enough to reliably pass LPIC-1.
Sample cards from the LPIC-1 flashcard bank. Read the question, think of the answer, then read the explanation below.
A systems administrator needs to change the permissions of the file /home/user/script.sh so that the owner can read, write, and execute; the group can read and execute; and others have no access. Which command accomplishes this?
chmod 750 /home/user/script.sh
Chmod 750 sets the permissions to rwxr-x---, which gives the owner read, write, and execute (7), the group read and execute (5), and others no access (0). This matches the requirement exactly.
Refer to the exhibit. An administrator needs to edit /etc/example.conf to change setting1 to 'production' and add a new line 'setting2=value' after the include line. The file must be edited in place without creating a backup. Which command sequence achieves this?
sed -i 's/setting1=default/setting1=production/' /etc/example.conf; sed -i '/^include /a\nsetting2=value' /etc/example.conf
The first sed command uses the -i flag to edit the file in place without a backup, and the substitution 's/setting1=default/setting1=production/' changes the existing setting. The second sed command uses the 'a' (append) command after the line matching '^include ' to add the new line 'setting2=value' after it, also with -i to avoid creating a backup.
A system administrator wants to mount a USB flash drive formatted with the ext4 filesystem. The device is detected as /dev/sdc1. Which command should be used to mount the device to /mnt/usb?
mount /dev/sdc1 /mnt/usb
The standard mount syntax is `mount [options] <device> <mountpoint>`. For ext4 filesystems, the kernel auto-detects the type, so the `-t ext4` option is unnecessary. While option D is syntactically valid, it is considered incorrect here because it includes an extraneous `-t ext4` flag; the question expects the simplest and most straightforward command. Option A is incorrect because `-a` mounts all filesystems listed in /etc/fstab, not a specific device. Option B is incorrect because the arguments are reversed (device must come before the mount point). Therefore, the command that correctly mounts /dev/sdc1 to /mnt/usb is `mount /dev/sdc1 /mnt/usb`.
A Linux system has two SATA disks: /dev/sda (250GB) and /dev/sdb (500GB). The administrator wants to create a logical volume group named 'vgdata' using partitions on both disks, then create a 600GB logical volume named 'lvdata' for a database. Which sequence of commands should be used?
pvcreate /dev/sda1 /dev/sdb1; vgcreate vgdata /dev/sda1 /dev/sdb1; lvcreate -L 600G -n lvdata vgdata
It follows the proper LVM sequence: first create physical volumes (PVs) on partitions /dev/sda1 and /dev/sdb1 (the partitions on the two disks given in the scenario), then create the volume group 'vgdata' from those PVs using vgcreate, and finally create the logical volume 'lvdata' with a size of 600GB using lvcreate. This order ensures that the PVs exist before the VG is created, and the VG exists before the LV is created. Only option C uses the correct device names that match the system's disks (/dev/sda and /dev/sdb).
A system administrator needs to install the latest version of a package named 'webapp' from a third-party repository that has been added to the system. Which command should be used to update the package list and install the package in one step?
apt-get update && apt-get install webapp
It first runs `apt-get update` to refresh the local package index from all configured repositories (including the third-party one), then uses `&&` to conditionally execute `apt-get install webapp` only if the update succeeds. This ensures the latest version available from the third-party repository is fetched and installed in a single command sequence.
A Linux administrator is troubleshooting a package dependency issue. When attempting to install package 'foo', the package manager reports a missing dependency 'libbar.so.2'. Which of the following is the most appropriate next step?
Use 'apt-file search libbar.so.2' or 'dnf provides libbar.so.2' to find the package that contains the file
The error indicates that the file 'libbar.so.2' is missing from the system. The most appropriate next step is to identify which package provides this file, so that it can be installed to satisfy the dependency. On Debian-based systems, 'apt-file search' queries the package repository metadata to find the package containing a specific file; on Red Hat-based systems, 'dnf provides' performs the same function. This targeted search is the correct first troubleshooting step before any installation or library cache update.
A system administrator notices that the NTP service on a Linux server is not synchronizing time with external NTP servers. The administrator runs 'ntpq -p' and sees that all servers listed have a 'reach' value of 0. Which of the following is the most likely cause?
A firewall is blocking UDP port 123.
The `reach` value of 0 in `ntpq -p` output indicates that the NTP client has received no responses from any of the configured servers. Since NTP uses UDP port 123 for communication, a firewall blocking this port would prevent the client from sending or receiving NTP packets, resulting in zero reachability. This is the most common cause when all servers show a reach of 0.
A web server running Apache on Linux is experiencing slow response times. The administrator runs 'netstat -tuln' and sees many connections in TIME_WAIT state. Which of the following is the best course of action to improve performance?
Enable TCP keepalive and adjust kernel parameters for faster reuse.
TIME_WAIT connections indicate that the server is waiting for lingering packets before fully closing TCP sockets. Enabling TCP keepalive and adjusting kernel parameters like net.ipv4.tcp_tw_reuse (or net.ipv4.tcp_tw_recycle in older kernels) allows the kernel to reuse sockets in TIME_WAIT state for new connections, reducing resource exhaustion and improving performance under high connection rates.
A system administrator wants to ensure that the syslog service starts automatically on boot and is running immediately without a reboot. Which command sequence should be used?
systemctl enable --now syslog
`systemctl enable --now syslog` combines enabling the service to start automatically on boot and starting it immediately in a single command. The `--now` flag triggers an immediate start after enabling, fulfilling both requirements without needing a reboot.
A 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?
pgrep cron
`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 writes a script that extracts data from a CSV file and inserts it into a database. The script works correctly when run manually but fails when executed by cron. Which environment variable is most likely causing the issue?
PATH
When a script runs manually, the user's interactive shell inherits a fully populated PATH environment variable that includes directories like /usr/local/bin, /usr/bin, and possibly custom script directories. Cron jobs, however, execute with a minimal environment, and the default PATH for cron is often just /usr/bin:/bin. If the script relies on commands (e.g., mysql, psql, or custom scripts) located outside these directories, cron will fail with a 'command not found' error. Setting the full PATH explicitly inside the script or in the crontab file resolves the issue.
A developer needs to ensure a bash script exits immediately if any command fails, and also prints each command before executing it. Which set of shell options should be used at the beginning of the script?
set -ex
`set -ex` combines two essential shell options: `-e` (errexit) causes the script to exit immediately if any command returns a non-zero exit status, and `-x` (xtrace) prints each command (after expansion) to stderr before executing it. This is the standard way to achieve both behaviors in a single line, as required by the question.
A system administrator notices that the server's clock is consistently off by several minutes. Which service should be used to synchronize the time with an external time source?
ntpd
The Network Time Protocol (NTP) daemon (ntpd) is the traditional and widely used service for synchronizing a server's clock with an external time source. It continuously adjusts the system time by communicating with NTP servers, compensating for clock drift and network delays to maintain accurate time. This makes ntpd the correct choice for resolving a consistent clock offset of several minutes.
During boot, the kernel must mount the root filesystem. Which of the following is responsible for providing the kernel with the location of the root filesystem?
boot loader
The boot loader (e.g., GRUB) is responsible for loading the kernel into memory and passing it the location of the root filesystem via kernel command-line parameters such as `root=`. Without this parameter, the kernel would not know which block device or partition to mount as `/`. The boot loader reads configuration files (e.g., `grub.cfg`) that specify this parameter, making it the direct provider of the root filesystem location.

Both flashcards and practice questions are evidence-based study tools. The difference is in what they train:
Flashcards — concept retention
Best for memorising definitions, acronyms, protocol behaviours, command syntax, and conceptual distinctions. Use flashcards to build the foundational vocabulary that LPIC-1 questions assume you know.
Best in: weeks 1–3
Practice tests — application
Best for applying concepts to realistic scenarios, eliminating distractors, and building exam stamina.LPIC-1 questions test scenario reasoning — not just recall — so practice tests are essential.
Best in: weeks 3–6
The most effective LPIC-1 study plan combines both: use flashcards for the first 2–3 weeks to build conceptual foundations, then shift to practice tests and mock exams in the final 2–3 weeks to apply and benchmark that knowledge. Most candidates who pass on their first attempt use both tools.
