Partly checked. None of the 40 questions here has been read against the cited source by a person. 40 questions have been checked against their cited clause by an automated pass — which is not the same thing, and is not a signature.
Only questions a person has signed for are used in mock exams here. That is the whole difference between the two kinds of checking above.
How these questions are written — where each question comes from, what the verification ledger records, and what happens when one is found wrong.
What this objective covers
The 40 questions written for this objective cite 3 LPI exam objectives (101.1, 101.2, 101.3) and 24 manual pages (acpid(8), boot(7), bootparam(7), depmod(8), dmesg(1), dracut(8), efibootmgr(8), grub-mkconfig(8), hier(7), initrd(4), inittab(5), journalctl(1), journald.conf(5), lsmod(8), lsusb(8), modprobe.d(5), proc(5), shutdown(8), systemctl(1), systemd-analyze(1), systemd.kill(5), systemd.special(7), systemd.unit(5), wall(1)).
They break down as 28 single-answer questions, 6 choose-several questions and 6 type-the-answer questions.
Drill this objective
The trainer can run a short practice set drawn from this objective alone, which is what the weight column above is for: revise the heavy objectives first.
Questions on this objective (page 2 of 2)
- You have added GRUB_TIMEOUT=10 and a kernel argument to /etc/default/grub on a GRUB 2 system. The next boot ignores both. What was missed? machine-checked
- On a Red Hat family server you moved the root filesystem onto an LVM logical volume and updated the kernel's root= argument accordingly. The next boot stops in an emergency shell with 'unable to find a live root filesystem'. Which command addresses the cause? machine-checked
- dmesg output prefixes every line with a figure such as [ 12.884301 ], and you need to correlate a disk error with an incident that happened at a known wall-clock time. Which option prints dates and times instead? machine-checked
- A colleague added a kernel argument at the boot loader menu and you want to confirm that the running kernel actually received it. Type the full path of the virtual file that shows the command line the running kernel was started with. machine-checked
- Which sequence correctly describes a modern Linux boot from the moment the firmware hands control to the boot loader? machine-checked
- After an unexplained reboot you run `journalctl -b -1` and are told that no persistent journal was found, although the current boot's messages are readable. What makes the previous boot's messages available in future? machine-checked
- Select the THREE items that a typical Linux installation keeps in /boot. machine-checked
- A systemd server now takes almost two minutes to reach its default target and you want a list of every unit ranked by how long it took to initialise. Which command produces it? machine-checked
- Select the THREE true statements about the initramfs. machine-checked
- A cloned virtual machine panics with 'VFS: Unable to mount root fs on unknown-block(0,0)' because the disk it was cloned from had a different device name. Which kernel parameter tells the kernel which filesystem to mount as root? machine-checked
- An old runbook instructs you to bring a server to runlevel 3. On the systemd machine in front of you, which target is the equivalent state? machine-checked
- You are auditing a systemd installation from a rescue system, with its filesystems mounted but nothing of it running, and must determine which target it boots into. Which item on disk records that choice? machine-checked
- Before a maintenance window you must take a running systemd server down to the rescue state immediately, stopping the services that are not part of it, while leaving the machine's normal boot behaviour unchanged. Which command does that? machine-checked
- Ten minutes before a planned database restart you want a warning to appear on the terminals of everyone currently logged in, without initiating any shutdown. Which command sends it? machine-checked
- A legacy SysVinit appliance boots into runlevel 5 and must instead come up in runlevel 3 at every boot. Which line in /etc/inittab do you change? machine-checked
- `systemctl stop backup.service` appears to hang for a minute and a half, then returns, and the journal records that the process was killed. What did systemd do? machine-checked
- A shutdown was scheduled earlier with `shutdown -h 23:00` and the maintenance has been called off. Which command cancels it? machine-checked
- On a headless server the short press of the power button should run a site-specific script that drains the machine before it halts. Which daemon receives that ACPI event from the kernel and runs a configured handler? machine-checked
- Select the THREE true statements about where systemd unit files live and how changes to them take effect. machine-checked
- You have inherited a systemd machine and want to know, before rebooting it, which target it will come up in. Type the command that prints the configured default target. machine-checked
