System Architecture

LPIC-1 Practice Questions

System Architecture is 15% of LPIC-1 and covers the machine underneath Linux: hardware, boot firmware, kernel modules, and the sysfs/procfs interfaces. Exam 101 tests it through scenario questions on BIOS/UEFI versus MBR/GPT partitioning, GRUB 2 configuration and recovery, runlevels and systemd targets, plus udev and kernel module handling.

What this objective tests

LPIC-1 System Architecture — Key Topics

Candidates must configure GRUB 2, manage systemd targets and kernel modules with systemctl, lsmod, and modprobe, and inspect /proc and /sys. Get GRUB 2 bootloader recovery right, since a broken boot blocks everything else.

Configuring GRUB 2 bootloader options and recovering a system that fails to boot
Identifying BIOS/MBR versus UEFI/GPT partitioning schemes and their boot implications
Managing kernel modules with lsmod, modprobe, modinfo, insmod and /etc/modprobe.d
Switching runlevels and systemd targets, and inspecting hardware via lspci, lsusb, dmidecode

Common exam traps

Where candidates lose marks on System Architecture

⚠Editing /boot/grub/grub.cfg directly instead of the source files in /etc/grub.d and /etc/default/grub
⚠Assuming modprobe and insmod are interchangeable; insmod cannot resolve module dependencies automatically
⚠Confusing BIOS/MBR limits with UEFI/GPT, such as expecting an EFI System Partition on a legacy BIOS install

LPIC-1 System Architecture — Practice Questions

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?

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?

An administrator needs to ensure that a specific kernel module is loaded automatically at boot. Which file should be used to permanently load the module?

Refer to the exhibit. The system has a single disk with three partitions. Which partition contains the root filesystem?

Exhibit

Refer to the exhibit. How many SATA controllers are detected, and what is the connection speed of the SSD?

Exhibit

Arrange the steps to configure a firewall rule using iptables to allow SSH.

Which command displays the system's architecture (e.g., x86_64)?

A system administrator needs to create a new Logical Volume (LV) in an existing LVM setup. Which sequence of commands is correct?

A sysadmin wants to ensure a specific kernel module is automatically loaded at boot. Which method is considered best practice?

During boot, a sysadmin sees the message 'Buffer I/O error on device sda1, logical block 0'. What does this most likely indicate?

Which TWO files are used to configure kernel boot parameters in GRUB?

Which THREE of the following are valid systemd targets?

The system administrator wants to use the entire sdb disk as a single partition. Which command will partition sdb with a single partition occupying the whole disk?

Exhibit

A kernel module fails to load with the error 'modprobe: FATAL: Module xyz not found in directory /lib/modules/$(uname -r)'. What is the most likely cause?

After modifying the /etc/fstab file, an administrator runs the command mount -a and receives the error 'mount: /data: special device /dev/sdb1 does not exist'. What is the most likely issue?

Which TWO commands can be used to display information about the CPU(s) in a Linux system? (Choose two.)

Which TWO conditions would cause the boot process to fall back to the GRUB rescue shell? (Choose two.)

Which THREE of the following are valid runlevels in a traditional SysV init system? (Choose three.)

Refer to the exhibit. How many physical disks are detected by the kernel, and what are their sizes?

Exhibit

The system is unable to mount a filesystem that should be identified by UUID 1234-5678. The administrator checks /etc/fstab and finds the entry: UUID=1234-5678 /data ext4 defaults 0 2. What is the most likely cause of the mount failure?

Exhibit

Refer to the exhibit. What is the current default target?

Exhibit

A server with UEFI firmware and GPT partitioning has a corrupted bootloader. Which command can be used to reinstall GRUB in UEFI mode?

Which file is used by GRUB to load the kernel at boot time?

An administrator runs 'lsmod' and sees a module with a usage count of 1. What does this indicate?

A system has multiple CPUs but only one is being used. Which file under /sys/ can be checked to verify CPU online status?

A Linux system using systemd fails to reach the default target after a recent change. The administrator wants to boot into a minimal environment to troubleshoot. Which kernel parameter should be added at the GRUB prompt?

A system administrator needs to blacklist the kernel module 'pcspkr' to disable the PC speaker. Which is the correct method?

Which THREE of the following are valid systemd targets?
