Question 1

Which of the following information is stored within the BIOS?
A) Boot device order
B) Linux kernel version
C) Timezone
D) Hardware configuration
E) The system's hostname

Accepted Answer

The BIOS stores the boot device order and hardware configuration settings, which are essential for the initial hardware setup and boot process.

Question 2

During a system boot cycle, what program is executed after the BIOS completes its tasks?
A) The bootloader
B) The inetd program
C) The init program
D) The kernel

Accepted Answer

The bootloader program is executed after the BIOS completes its tasks. The bootloader is responsible for loading the operating system kernel into memory and starting its execution.

Question 3

Which of the following are init systems used within Linux systems?
A) startd
B) systemd
C) Upstart
D) SysInit
E) SysV init

Accepted Answer

systemd, Upstart, and SysV init are all init systems used within Linux systems.

Question 4

Which of the following commands lists the dependencies of a given dpkg package?
A) apt-cache depends-on package
B) apt-cache dependencies package
C) apt-cache depends package
D) apt-cache requires package

Accepted Answer

Question 5

What is the first program that is usually started, at boot time, by the Linux kernel when using SysV init?
A) /lib/init.so
B) /sbin/init
C) /etc/rc.d/rcinit
D) /proc/sys/kernel/init
E) /boot/init

Accepted Answer

The first program that is usually started, at boot time, by the Linux kernel when using SysV init is /sbin/init. It is the parent process of all other processes and it is responsible for starting and stopping services and daemons during system start-up, as well as for managing the system runlevels.

Question 6

Which of the following commands is used to update the list of available packages when using dpkg based package management?
A) apt-get update
B) apt-get upgrade
C) apt-cache update
D) apt-get refresh
E) apt-cache upgrade

Accepted Answer

The command "apt-get update" is used to update the list of available packages when using dpkg based package management. This command synchronizes the package index files with the sources defined in the "sources.list" file to ensure that the latest version of each package is known. It does not install or upgrade any packages.

Question 7

Which of the following options for the kernel's command line changes the systemd boot target to rescue.target instead of the default target?
A) systemd.target=rescue.target
B) systemd.runlevel=rescue.target
C) systemd.service=rescue.target
D) systemd.default=rescue.target
E) systemd.unit=rescue.target

Accepted Answer

The correct option to change the systemd boot target to rescue.target is systemd.unit=rescue.target. This option sets the default system unit to rescue.target, which is the systemd target for rescue mode. Option A is incorrect because systemd.target is not a valid option for changing the default target. Option B is incorrect because systemd.runlevel is not a valid option for changing the target. Option C is incorrect because systemd.service is used to start or stop individual services, not change the default target. Option D is incorrect because systemd.default is not a valid option for changing the target.

Question 8

What of the following statements are true regarding /dev/ when using udev?
A) Entries for all possible devices get created on boot even if those devices are not connected.
B) Additional rules for udev can be created by adding them to /etc/udev/rules.d/.
C) When using udev, it is not possible to create block or character devices in /dev/ using mknod.
D) The /dev/ directory is a filesystem of type tmpfs and is mounted by udev during system startup.
E) The content of /dev/ is stored in /etc/udev/dev and is restored during system startup.

Accepted Answer

Udev allows for additional rules to be added in /etc/udev/rules.d/. The /dev/ directory is a tmpfs filesystem managed by udev, which dynamically creates device nodes.

Question 9

What information can the lspci command display about the system hardware?
A) Device IRQ settings
B) PCI bus speed
C) System battery type
D) Device vendor identification
E) Ethernet MAC address

Accepted Answer

C) nomesg
D) quiet

Accepted Answer

The "quiet" kernel parameter instructs the kernel to suppress most boot messages.

Question 15

Which of the following statements is correct when talking about /proc/?
A) All changes to files in /proc/ are stored in /etc/proc.d/ and restored on reboot.
B) All files within /proc/ are read-only and their contents cannot be changed.
C) All changes to files in /proc/ are immediately recognized by the kernel.
D) All files within /proc/ are only readable by the root user.

Accepted Answer

/proc/ is a virtual filesystem that provides an interface to kernel data and status information. Any changes made to files within /proc/ are immediately recognized by the kernel. /etc/proc.d/ is not a directory that is used to store changes made to /proc/ files. Some files within /proc/ may be read-only, but not all of them. Additionally, not all files within /proc/ are only readable by the root user.

Question 18

Which SysV init configuration file should be modified to disable the ctrl-alt-delete key combination?
A) /etc/keys
B) /proc/keys
C) /etc/inittab
D) /proc/inittab
E) /etc/reboot

Accepted Answer

The /etc/inittab file controls how the init process behaves on a SysV init system. This file can be used to configure various system settings, including what actions are triggered when certain key combinations are pressed. To disable the ctrl-alt-delete key combination, the line that starts with "ca::ctrlaltdel" should be commented out by adding a "#" character at the beginning of the line.

Question 19

Which of the following options is used in a GRUB Legacy configuration file to define the amount of time that the GRUB menu will be shown to the user?
A) hidemenu
B) splash
C) timeout
D) showmenu

Accepted Answer

The "timeout" option is used in a GRUB Legacy configuration file to define the amount of time (in seconds) that the GRUB menu will be shown to the user before automatically booting the default entry. The other options listed ("hidemenu", "splash", "showmenu") do not affect the timeout value.

Question 20

Which of the following commands brings a system running SysV init into a state in which it is safe to perform maintenance tasks?
A) shutdown -R 1 now
B) shutdown -single now
C) init 1
D) telinit 1
E) runlevel 1

Accepted Answer

Both "init 1" and "telinit 1" bring the system to runlevel 1, which is a single-user mode suitable for maintenance tasks.
