1) What is basic boot process for Linux systems (in correct order)? a) Firmware stage, Bootloader stage, Kernel stage, Initialization stage b) Hardware stage, Kernel stage, Bootloader stage, Initialization stage c) Bootloader stage, Kernel stage, Initialization stage, Firmware stage  d) Kernel Stage, Bootloader stage, Firmware stage, Initialization stage 2) Which command is used to create a new initial RAM disk (initrd) image in a Linux environment? a) mkinitrd b) grub2-install c) grub2-mkconfig d) grub2-update 3) What file is the compressed kernel image typically named in a Linux boot process? a) grub.cfg b) initrd.img c) vmlinuz d) systemd.img 4) Which command is used to install the GRUB2 bootloader to a device in a Linux environment? a) grub2-installgrub2-mkconfig b) grub2-install c) mkinitrd d) dracut 5) Which boot source is used for network booting in a Linux environment? a) Kernel MBR b) Booting from Universal Serial Bus (USB) c) Booting from ISO d) Preboot eXecution Environment (PXE) 6) In the context of the Linux boot process, what is the primary purpose of the dracut command, and how does it differ from mkinitrd? a) dracut installs the GRUB2 bootloader, while mkinitrd creates an initial RAM disk. b) 'dracut' creates a more modular and extensible initramfs, allowing for better support of complex setups, whereas mkinitrd creates a more static initramfs. c) dracut updates the kernel, while mkinitrd installs kernel modules. d) dracut generates GRUB2 configuration files, whereas mkinitrd installs the GRUB2 bootloader. 7) Which command is used to change the default systemd target in a Linux environment? a) systemctl reboot b) systemctl isolate c) systemctl set-default d) systemctl status 8) Which of the following is a common step in troubleshooting a kernel panic in a Linux environment? (choose two) a) Checking the system logs for error messages or inspect hardware issues b) Using the systemctl status command to list active services c) Running mkinitrd to create a new initial RAM disk d) Executing grub2-mkconfig to update GRUB2 configuration files e) Choose different kernel from grub2 menu 9) When encountering a kernel panic during boot, which boot parameter can be added to the kernel command line in GRUB2 to obtain more detailed debugging information? a) nomodeset b) debug c) quiet d) splash 10) What parameter need to be Which GRUB2 configuration file directive is used to set the timeout duration for the boot menu in a Linux environment? a) GRUB_TIMEOUT b) GRUB_DEFAULT c) GRUB_CMDLINE_LINUX d) GRUB_HIDDEN_TIMEOUT 11) Which command will allow us to update boot loader code responsible for booting the system? a) sudo grub2-install b) sudo grub2-mkconfig c) sudo grub2-renew d) sudo grub2-reconfigure 12) Which command will update GRUB configuration file after changes have been made that effect the bootloader configuration? a) grub2-mkconfig b) grub2-reconfigure c) grub2-update d) grub2-refresh 13) What does systemd process do? a) Starts audio services b) Starts the kernel in kernel stage of boot process c) Initiated by kernel to start system services and GUI d) Initiated by kernel to load RAM disk into RAM 14) What image is generated by tools like mkinitrd or dracut at early stages of Linux boot process? It is also cpio archive that contains essential files and modules. a) mkdir.img b) initrd.img c) initddr.img d) initdrac.img 15) What command will allow us, after checking instability of newer kernel, to set permanently the older kernel for sometime? a) sudo grub2-set-default-1 b) sudo grub2-set-default-0 c) sudo grub2-set-default d) sudo grub2-set-old
