Question 1 of 93

During a system boot cycle, what program is executed after the BIOS completes its tasks?

The bootloader

The inetd program

The init program

The kernel

Correct Answer: A

Once the BIOS completes its tasks during a system boot cycle, the bootloader is the program that is executed next. The bootloader is responsible for loading the operating system's kernel into memory and starting it. The inetd and init programs are not executed immediately after the BIOS; the inetd is a super server daemon often used to manage internet services, and init is the first process started by the kernel after it has been loaded by the bootloader.

Question 2 of 93

Which run levels should never be declared as the default run level when using SysV init? (Choose TWO correct answers.)

Correct Answer: A, E

Run levels 0 and 6 should never be declared as the default run level when using SysV init. Run level 0 is used for shutting down the system, and run level 6 is used for rebooting the system. Setting either of these as the default run level would result in the system either continuously shutting down or rebooting, making it unusable.

Question 3 of 93

Which of the following statements is correct when talking about /proc/?

All changes to files in /proc/ are stored in /etc/proc.d/ and restored on reboot.

All files within /proc/ are read-only and their contents cannot be changed.

All changes to files in /proc/ are immediately recognized by the kernel.

All files within /proc/ are only readable by the root user.

Correct Answer: C

The /proc/ directory contains virtual files that represent the system's current state and kernel parameters. Changes made to writable files in /proc/ are immediately recognized by the kernel, allowing for real-time updates and configuration.

Question 4 of 93

What of the following statements are true regarding /dev/ when using udev? (Choose TWO correct answers.)

Entries for all possible devices get created on boot even if those devices are not connected.

Additional rules for udev can be created by adding them to /etc/udev/rules.d/.

When using udev, it is not possible to create block or character devices in /dev/ using mknod.

The /dev/ directory is a filesystem of type tmpfs and is mounted by udev during system startup.

The content of /dev/ is stored in /etc/udev/dev and is restored during system startup.

Correct Answer: B, D

Additional rules for udev can be created by adding them to /etc/udev/rules.d/, allowing for customization and configuration of device handling. The /dev/ directory is a filesystem of type tmpfs and is mounted by udev during system startup, implying that it is dynamically populated by udev as devices are detected. This means that entries are not pre-created on boot for all possible devices, contrary to what option A suggests. Contrary to option C, it is possible to manually create block or character devices using mknod, but this is generally managed by udev. Option E is incorrect as /dev/ is managed dynamically by udev and not stored or restored from a directory.

Question 5 of 93

Which of the following information is stored within the BIOS? (Choose TWO correct answers.)

Boot device order

Linux kernel version

Timezone

Hardware configuration

The system's hostname

Correct Answer: A, D

The BIOS (Basic Input/Output System) stores low-level settings that help start and configure the computer during boot. It typically includes the boot device order, allowing the system to know which devices to use for booting first. Additionally, the BIOS contains information about the hardware configuration of the system, such as the types and capacities of drives, memory, and connected peripherals.
