Question 6 of 179

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

Answer

Suggested Answer

The suggested answer is 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.

Which of the following commands reboots the system when using SysV init? (Choose TWO correct answers.)

Answer

Suggested Answer

The suggested answer is A, C.

To reboot the system using SysV init, you can use two commands: 'shutdown -r now' and 'telinit 6'. 'shutdown -r now' initiates an immediate reboot of the system, while 'telinit 6' instructs the init process to transition to runlevel 6, which is associated with a reboot. These commands are commonly used for rebooting systems running SysV init.

Which of the following are init systems used within Linux systems? (Choose THREE correct answers.)

Answer

Suggested Answer

The suggested answer is B, C, E.

In Linux systems, the init system is the first process started by the kernel during the boot process. Systemd is a popular init system used in many modern Linux distributions. Upstart was an event-based init system used in some Linux distributions as a replacement for the traditional init daemon but is now less common. SysV init is one of the original init systems used in Unix and Unix-like systems and was widely used in older Linux distributions before being largely replaced by systemd.

Question 10 of 179

What information can the lspci command display about the system hardware? (Choose THREE correct answers.)

Answer

Suggested Answer

The suggested answer is A, B, D.

The lspci command is used to display information about PCI devices on a system. It can provide details on various aspects of these devices. The command can display device IRQ settings, giving insights into the hardware interrupts assigned to PCI devices. Furthermore, it can show the PCI bus speed, which helps in understanding the data transfer capabilities of the bus. Additionally, it provides device vendor identification, revealing the manufacturers of the PCI devices in the system. Therefore, the three correct pieces of information that lspci can display are device IRQ settings, PCI bus speed, and device vendor identification.
