問題文
An administrator has to edit the generated GRUB 2 configuration file on an Oracle Linux 8 server whose hardware uses UEFI firmware rather than legacy BIOS. Which directory holds that generated file on this server, and what accounts for that location?
選択肢
- /etc/default/grub, because UEFI firmware reads that shell-style configuration directly and GRUB 2 leaves the generated file out on such a system
- /boot/efi/EFI/redhat, because the boot configuration of a UEFI system is kept on a dedicated FAT32-formatted partition whose EFI folder is mounted inside /boot/efi after the system has booted
- /boot/grub2, because the firmware type, whether UEFI or legacy BIOS, decides which kernel image GRUB 2 loads but leaves the configuration path unchanged
- /boot/efi/EFI/oracle, because the vendor directory that holds the configuration on the FAT32 partition is named after the distribution of the system
