Question 1 of 121

SIMULATION -

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

Show 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 choices
Show answer

Correct answers: A, D, E

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 choices
Show answer

Correct answers: 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 choices
Show answer

Correct answer: 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?

Show 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.

Stories from the certified

Charles Sirois
Canada
As this was my first certification exam, I was understandably nervous about what to expect. These study materials made the preparation process much easier, and many of the questions closely reflected those on the actual exam.
Lance Chambers
United States
Wasted about a month going through the free dump sites scattered all over reddit, half the answers were wrong and the other half were for a version of the exam that doesn't even exist anymore. Eventually gave in and paid the small fee here, and the difference was night and day.
Alisha Kelly
Italy
Honestly, I had already gone through the official documentation quite thoroughly, but still didn't feel fully confident going in. This helped things finally click for me. I realized I knew the material, but just hadn't connected all the pieces yet.
Casper Claassen
Netherlands
Used this along with Microsoft Learn and the combo worked really well. The practice questions made the stuff I'd read actually stick. Passed first attempt, no complaints from me.
Gabriele Ghesla
Italy
The content is accurate and clearly presented, and it's more affordable than competitors. The team has been incredibly responsive whenever I've had an issue, and they've been open to small changes that improve the platform.

I don't usually leave reviews, but this one felt worth sharing. The questions were quite close to what actually appeared on the exam, more than I expected. I spent about a week going through the material before my test, and it helped me feel more prepared.

Passed ITIL 4 Foundation with 87%. Material was enough by itself.
