LCA Linux System Installation & Configuration

Question 1

What is the first step when installing Linux on a new system?

Accepted Answer

Creating a bootable installation media

Answer

The very first step when installing Linux on a new system is to create a bootable installation media, such as a USB drive or DVD. This media contains the Linux operating system installer and allows the computer to boot into the installation environment. Without a bootable medium, the system cannot load the necessary files to begin the installation process.

Question 2

Which Linux installation method allows installation over the network?

Accepted Answer

PXE Boot Network installation

Answer

PXE (Preboot eXecution Environment) Boot Network installation is a method that allows a computer to boot and install an operating system over a network without needing local storage or an optical drive. This is particularly useful for deploying Linux to multiple machines efficiently in a corporate or data center environment. It centralizes the installation process and reduces manual effort.

Question 3

What is the purpose of the partitioning step during Linux installation?

Accepted Answer

To divide the disk into logical sections

Answer

During Linux installation, partitioning is the process of dividing a physical hard disk drive into one or more logical sections, known as partitions. Each partition can then be formatted with a specific filesystem and used for different purposes, such as the root directory, swap space, or user home directories. This organization helps manage disk space and system resources effectively.

Question 4

Which bootloader is most commonly installed with Linux systems?

Accepted Answer

GRUB

Answer

GRUB (GRand Unified Bootloader) is the most commonly installed bootloader with modern Linux systems. Its primary function is to load the operating system kernel into memory and pass control to it, allowing the system to start up. GRUB supports multiple operating systems and offers a flexible configuration for booting various kernels or even other operating systems installed on the same machine.

Question 5

What is the default file system commonly used during Linux installation?

Accepted Answer

Ext4

Answer

Ext4 (Fourth Extended Filesystem) is the default and most commonly used file system for Linux installations. It is a journaling file system that offers improved performance, reliability, and larger file system and file size limits compared to its predecessors. Its robustness and widespread adoption make it the standard choice for most Linux distributions.
