LPIC-1 Exam 101-500 has 60 questions in 90 minutes with a 500-of-800 scaled passing score. Topic weights: System Architecture (8), Linux Installation and Package Management (12), GNU and Unix Commands (26), and Devices, Linux Filesystems, FHS (14). Mix of multiple-choice and fill-in-the-blank. The fill-ins demand exact command names, paths, and option flags — typos count as wrong. Questions emphasize ls, cd, find, grep, sed, awk, head, tail, cut, sort, uniq, wc, xargs, tar, gzip, dd, lspci/lsusb, dmesg, journalctl, rpm/dnf, dpkg/apt, fdisk, parted, mkfs, mount, /etc/fstab, ext4/XFS, hard/soft links, and FHS directories. Exam fee is $200 USD. Certification is valid 5 years before recertification.

Sample LPIC-1 101-500 Practice Questions

Try these sample questions to review concepts for the LPIC-1 101-500 exam. Each question includes a detailed explanation. Start the interactive quiz above for the full 141+ question experience with AI tutoring.

1Which command displays a list of all PCI devices attached to the system?
A.lsusb
B.lspci
C.lshw -pci
D.pciinfo
Explanation: lspci lists PCI buses and devices. It reads from /proc/bus/pci and /sys/bus/pci. Use lspci -v for verbose output and lspci -k to show kernel modules in use. lsusb is for USB devices; pciinfo is not a real command; lshw -pci is not the standard form (lshw uses -class).
2Which file (or directory) contains kernel ring buffer messages and can be displayed with the dmesg command?
A./var/log/messages
B./proc/kmsg and /dev/kmsg
C./etc/dmesg.conf
D./var/run/dmesg
Explanation: dmesg prints the kernel ring buffer. util-linux dmesg reads it through /dev/kmsg by default (kernels 3.5 and later) or through the syslog(2) interface, and /proc/kmsg is the older interface that logging daemons such as klogd read. /var/log/messages contains kernel messages only after a syslog daemon has written them there, and /etc/dmesg.conf does not exist.
3Which systemd command sets the default boot target to the multi-user (non-graphical) target?
A.systemctl set-default multi-user.target
B.systemctl isolate multi-user.target
C.systemctl enable multi-user
D.systemctl default-target multi-user
Explanation: systemctl set-default <target>.target updates the symlink /etc/systemd/system/default.target to point to the chosen target unit, persisting across reboots. systemctl isolate switches the running system but does not persist. systemctl enable activates a unit but doesn't change the default target.
4What is the legacy SysV runlevel equivalent of systemd's graphical.target?
A.3
B.4
C.5
D.6
Explanation: Runlevel 5 corresponds to multi-user with graphical login (graphical.target). Runlevel 3 maps to multi-user.target (text mode multi-user), runlevel 1 to rescue.target, runlevel 0 to poweroff.target, and runlevel 6 to reboot.target.
5Which command shows information about USB devices attached to the system, including bus and device IDs?
A.lsusb
B.lspci
C.lsmod
D.usbinfo
Explanation: lsusb lists USB devices with their bus number, device number, vendor:product ID, and name, and is part of the usbutils package. Use lsusb -v for verbose descriptors or lsusb -t for a tree view. lspci is the PCI equivalent, lsmod lists loaded kernel modules rather than devices, and usbinfo is not a standard Linux command.
6Which filesystem provides an interface to kernel data structures and contains a directory for each running process?
A./dev
B./sys
C./proc
D./run
Explanation: /proc is a virtual filesystem that exposes kernel and process information. Each running PID has a directory like /proc/1234. /sys exposes device and driver information via sysfs. /dev contains device nodes. /run holds runtime data since boot.
7An administrator wants to verify which kernel module currently controls the network interface card. Which command and option provides this information?
A.lsmod -k eth0
B.lspci -k
C.modinfo eth0
D.ifconfig -m
Explanation: lspci -k displays the kernel driver in use and any kernel modules that could handle each PCI device. This is the standard way to confirm which driver claimed a NIC, GPU, or other PCI device. modinfo describes a module, not which device uses it. lsmod -k is not a real option.
8Which command immediately switches a running systemd system to rescue (single-user) mode?
A.systemctl set-default rescue.target
B.systemctl isolate rescue.target
C.systemctl enable rescue.target
D.telinit 3
Explanation: systemctl isolate rescue.target starts rescue.target and its dependencies and stops every unit the target does not require, so the system drops to rescue mode now. 'systemctl rescue' is a documented shortcut for the same isolate operation, and 'telinit 1' reaches it through SysV runlevel compatibility (runlevel 1 maps to rescue.target).
9Which file controls module options and aliases that are applied when modules are loaded?
A./etc/modules
B./etc/modprobe.d/*.conf
C./proc/modules
D./lib/modules/*/modules.dep
Explanation: /etc/modprobe.d/*.conf (and /etc/modprobe.conf on older systems) contains options, aliases, install/remove commands, and blacklist directives consulted by modprobe. /etc/modules lists modules to load at boot but doesn't set options. /proc/modules is read-only kernel state.
10Which command displays information about modules currently loaded into the kernel?
A.modinfo
B.modprobe -l
C.lsmod
D.modlist
Explanation: lsmod reads /proc/modules and lists every module currently loaded, with its size and use count. modinfo describes one module by name, whether or not it is loaded. modprobe -l was a listing option in the old module-init-tools and has been removed from kmod's modprobe. modlist is not a standard command.

LPIC-1 101-500: Suggested Study Strategy

1Live in the shell — pwd, cd, ls, cp, mv, mkdir, rm, find, grep, sed, awk should be muscle memory before exam day
2Drill the fill-in-the-blank style: type 'pwd', '/etc/fstab', 'mount', '-r', exactly — typos and singular/plural mistakes count as wrong
3Memorize the FHS: /etc (config), /var (variable data, logs), /usr (read-only programs), /opt (optional apps), /tmp (temp), /proc and /sys (virtual)
4Both Debian (dpkg/apt) and RPM (rpm/dnf/yum/zypper) families appear — know -i install, -e/-r remove, -q query, -U upgrade for both worlds
5Streams and redirection: practice >, >>, <, 2>, 2>&1, &>, |, tee, xargs until pipelines feel natural
6Practice fdisk/parted/mkfs/mount workflow: partition → format → mount → fstab entry → verify with mount/df
7Hard vs symbolic links: 'ln src dst' (hard, same inode, no cross-filesystem); 'ln -s src dst' (symbolic, can cross filesystems and dangle)
