⩥ Which of the following has a process ID (PID) of 1?
Answer: The initial process
⩥ What component is responsible for loading and executing the initial
process?
Answer: OS kernel
⩥ Which of the following is the last step the OS kernel performs during
a UEFI boot on a Linux machine?
Answer: Loads and executes either the init (Initial) process (for older
distributions) or the systemd process (for newer distributions).
⩥ You have a system with more than one Linux operating system
installed. During the system's bootup process, which component loads a
splash screen, allowing you to choose which operating system you want
to run?
Answer: The secondary bootloader
,⩥ During the bootloader phase of the UEFI boot process, an optional
initial RAM disk image called initramfs is loaded into memory.
Which of the following BEST describes the initramfs image? (Select
two.)
Answer: A custom version of the init program containing all the drivers
and tools needed at boot.
Used to mount the file system and load the kernel into RAM.
⩥ The vmlinux and Linux Linux kernel executables contain information
that can be used for what purpose? (Select the correct answer from the
drop-down list.)
Answer: Debugging
⩥ Which of the following boot methods provides higher performance
(larger files and greater distances than TFTP) and is often used to
replace the PXE boot method of network deployment?
Answer: HTTP
⩥ You have a Linux server where the bootloader is malfunctioning and
can no longer boot. You want to re-install a new copy of Linux over the
network using the firmware on the server's network card, and should be
as simple to use as possible.
Which of the following boot methods will BEST meet your re-
installation needs?
,Answer: PXE
⩥ Which of the following are requirements for a PXE boot to work on
your Linux client computer?
Answer: The client BIOS/UEFI must be configured to use PXE.
The NIC in the client computer must support PXE boot.
⩥ If an attacker boots into single-user mode, they will be logged in
automatically as the root user without being required to enter the root
password.
Which of the following is the BEST measure you should take to prevent
this event from happening?
Answer: Set a bootloader password.
⩥ Which directory contains the configuration file for GRUB 2?
Answer: /boot/grub2/
⩥ You have a dual-boot system with a Linux and a Windows operating
system. You need to configure the GRUB 2 bootloader to display the
menu for 12 seconds before it automatically boots the default operating
system.
Which of the following is the BEST first step to configure the
bootloader?
, Answer: Edit the timeout parameter in the /etc/default/grub file to say
GRUB_TIMEOUT=12.
⩥ What is the full path and filename of the GRUB 2 file that is used for
editing the default behavior of the bootloader menu?
Answer: /etc/default/grub
⩥ You are editing the /etc/default/grub file. Which option should you use
to set the default operating system?
Answer: GRUB_DEFAULT=
⩥ Drag the GRUB 2 file or directory on the left to the correct
description on the right.
Answer: The GRUB2 configuration file (non-editable). =
/boot/grub2/grub.cfg
The GRUB2 directory for script files. = /etc/grub.d/
The GRUB2 configuration file (editable). = /etc/default/grub
The script that identifies kernels on the root device and creates menu
entries. = 10_linux
The script file that allows menu entries to be modified. = 40_custom
