Which of the following information is stored within the BIOS? (Choose TWO correct answers.)
Which of the following information is stored within the BIOS? (Choose TWO correct answers.)
The BIOS stores information crucial for the initial boot process of a computer and the configuration of its hardware. The boot device order, which determines the sequence in which bootable devices are checked for an operating system, is stored in the BIOS. Additionally, the BIOS houses details about the hardware configuration, such as connected devices and system memory, which it uses to initialize the hardware before the operating system takes over. Other information like the Linux kernel version, timezone, or the system's hostname are not stored in the BIOS; these are managed by the operating system.
Which of the following commands reboots the system when using SysV init? (Choose TWO correct answers.)
The command 'shutdown -r now' reboots the system immediately by sending a signal to init to switch to runlevel 6, which is designated for rebooting the system in SysV init. The command 'telinit 6' directly tells init to change to runlevel 6, thereby rebooting the system as well. Both commands effectively trigger a system reboot when using SysV init.
Which of the following are init systems used within Linux systems? (Choose THREE correct answers.)
Systemd is a modern init system used in many Linux distributions, responsible for starting and managing system services and daemons at boot time and during system operation. Upstart is an init system used in some Linux distributions, particularly older ones, as an alternative to the traditional SysV init system. SysV init is the traditional init system used in many Linux distributions, responsible for starting and managing system services and daemons at boot time and during system operation.
SUMULATION -
Which file in the /proc filesystem lists parameters passed from the bootloader to the kernel? (Specify the file name only without any path.)
cmdline - The file 'cmdline' in the /proc filesystem contains the command-line parameters that were passed to the kernel by the bootloader at boot time. These parameters can be used to configure the kernel and set options for the operating system. Therefore, the correct file name without any path is 'cmdline'.
What information can the lspci command display about the system hardware? (Choose THREE correct answers.)
The lspci command can display information about device IRQ settings, PCI bus speed, and device vendor identification. It is specifically used to list all PCI devices and their details, such as vendor and device IDs, class codes, and more. It does not provide information about system battery type or Ethernet MAC addresses, as those are not within the scope of the PCI bus information.
