Which file in the /proc filesystem lists parameters passed from the bootloader to the kernel? (Specify the file name only without any path.)
Answer

Suggested Answer

The correct file in the /proc filesystem that lists parameters passed from the bootloader to the kernel is 'cmdline'. This file contains the kernel command line arguments, which are passed to the kernel during the boot process.

Question 2 of 121
What information can the lspci command display about the system hardware? (Choose THREE correct answers.)
Answer

The lspci command is used to display information about PCI buses and details of devices connected to the PCI bus in a system. Specifically, it can provide information on device IRQ settings, device vendor identification, and Ethernet MAC addresses. However, it does not provide information on PCI bus speed or system battery type.

Question 3 of 121
Which of the following commands brings a system running SysV init into a state in which it is safe to perform maintenance tasks? (Choose TWO correct answers.)
Answer

Suggested Answer

The suggested answer is C, D.

To bring a system running SysV init into a state safe for maintenance tasks, the system must be switched to single-user mode, which is runlevel 1. The commands 'init 1' and 'telinit 1' both transition the system to runlevel 1. In single-user mode, only essential system services are running, and only the root user can log in, making it suitable for maintenance tasks. Other options either do not exist, do not change the runlevel, or are not standard commands for this purpose.

Question 4 of 121
What is the first program that is usually started, at boot time, by the Linux kernel when using SysV init?
Answer

Suggested Answer

The suggested answer is B.

The first program that is usually started, at boot time, by the Linux kernel when using SysV init is /sbin/init. This program is responsible for initializing the system, setting up the environment, and starting other system services and user processes. It acts as the parent process for all other processes on the system and manages system runlevels.

Question 5 of 121
SIMULATION -
Which command will display messages from the kernel that were output during the normal boot sequence?
Answer

Suggested Answer

The correct command to display messages from the kernel that were output during the normal boot sequence is 'dmesg'. The 'dmesg' command reads the kernel ring buffer, which contains messages and log information from the kernel, including information about the system boot process, hardware detection, device drivers, and other system events. By running the 'dmesg' command, you can view the output from the kernel that was generated during the boot process.
