,Linux Architecture & Boot Process (Q1–Q8)
Q1. A Linux administrator needs to determine which process was started directly by
the kernel during system initialization on a modern system using systemd. Which
process fulfills this role?
A. initrd
B. systemd
C. login
D. bash
Correct Answer: 🔴 B. systemd
Explanation: 🔹 The Linux kernel launches PID 1 during boot. On modern
distributions using systemd, the systemd process becomes PID 1 and manages
service initialization and system state transitions. initrd is a temporary filesystem,
login is started later, and bash is a user shell rather than the primary initialization
process.
Q2. A server fails to boot after a kernel upgrade. The administrator wants to select a
previous kernel version from the boot menu. Which component typically provides
this functionality?
A. cron
B. syslog
C. GRUB 2
D. udev
Correct Answer: 🔴 C. GRUB 2
Explanation: 🔹 GRUB 2 is the bootloader responsible for presenting boot options
and loading kernels. It allows administrators to choose older kernels when
troubleshooting. Cron schedules tasks, syslog handles logging, and udev manages
device events.
,Q3. Which command displays detailed CPU architecture information directly from the
system?
A. uname -m
B. lscpu
C. free -m
D. mount
Correct Answer: 🔴 B. lscpu
Explanation: 🔹 lscpu provides comprehensive processor architecture information
including cores, threads, and CPU features. uname -m only displays machine
architecture. free reports memory usage and mount displays mounted filesystems.
Q4. A Linux system uses runlevels for compatibility purposes. Which systemd target
most closely corresponds to the traditional multi-user text mode runlevel 3?
A. graphical.target
B. rescue.target
C. multi-user.target
D. reboot.target
Correct Answer: 🔴 C. multi-user.target
Explanation: 🔹 multi-user.target provides a non-graphical multi-user environment
similar to traditional runlevel 3. graphical.target includes a GUI, rescue.target is for
maintenance, and reboot.target initiates system restart.
Q5. Which command displays the currently running kernel version?
A. uname -r
B. ps -ef
C. df -h
D. lsmod
, Correct Answer: 🔴 A. uname -r
Explanation: 🔹 uname -r displays the active kernel release version. This is
commonly used after upgrades or troubleshooting. The other commands display
processes, filesystems, and kernel modules respectively.
Q6. An administrator wants to view currently loaded kernel modules. Which
command is most appropriate?
A. modprobe
B. insmod
C. lsmod
D. depmod
Correct Answer: 🔴 C. lsmod
Explanation: 🔹 lsmod lists all currently loaded kernel modules. modprobe and
insmod load modules, while depmod generates dependency information.
Q7. Which directory typically contains static bootloader files and Linux kernels?
A. /etc
B. /var
C. /home
D. /boot
Correct Answer: 🔴 D. /boot
Explanation: 🔹 The /boot directory contains kernel images, bootloader files, and
related configuration required during startup. The other directories serve
configuration, variable data, and user storage purposes.
Q8. What is the primary purpose of an initramfs image?
