Decent iOS support is also a welcome feature, if you love ![]() ![]() The fsck program (option A) fixes corrupt partitions, and the mount program (option C) is used to attach partitions to the virtual directory, so neither of those is correct. The kernel ring buffer, which you can view by typing dmesg, contains boot messages from the kernel thus option D is correct. Option E also specifies a common Linux configuration file directory, but it’s not used to store the GRUB bootloader program that the firmware can access. Option C specifies the common log file folder, but that doesn’t contain the GRUB bootloader program. Option A specifies the configuration folder used to store the GRUB configuration file and the kernel image file, but the actual GRUB bootloader program can’t be stored there. Some Unix systems use the /var/messages folder for storing log files, but Linux has not adopted this standard, so option B is also incorrect. The /etc folder is most often used for storing system and application configuration files, not boot logs, so option A is incorrect. Most Linux distributions store boot log files in the /var/log folder. Option E, the chkconfig program, is used to display the runlevels assigned to individual programs in the startup scripts and is not related to the boot messages, so it too is incorrect. Normally, it looks at the internal hard drive installed on the system however, if none is found, it can search other places. The BIOS firmware can look in multiple locations for a bootloader program. The /proc folder is unique in that the Linux kernel dynamically stores information about the system there, but it doesn’t store boot log information there. Mac app for google hangoutsThe boot partition in any hard drive may contain a bootloader, but it is not the MBR, which is run first by the firmware thus option B is incorrect. Thus option A is the only correct answer. The Master Boot Record (MBR) is located in only one place—on the first sector of the first hard drive on the workstation. Finally, many workstations provide the PXE boot option, which allows the workstation to boot remotely from a network server. Modern workstations now also provide the option to boot from a USB memory stick inserted into a USB port on the workstation. However, it is not used to store the bootloader files themselves, so option E is incorrect. Option E, the /boot/grub file, is used in GRUB Legacy and GRUB2 to store the bootloader configuration files, as well as the kernel image files. The /var folder is used to store variable files such as log files, not bootable files, so option C is incorrect. The /etc directory is used to store application and system configuration files, not bootloader programs, so option B is incorrect. The UEFI firmware always looks for the /boot/efi directory for bootloader programs, so option D is correct. The ESP is stored in the /boot/efi directory on Linux systems. Uefi file extension is not used in Linux, so option B is incorrect. Lst file extension, which is also used for GRUB Legacy configuration files, so it too is incorrect. Option A and option D specify file extensions used to identify GRUB2 (option A) and GRUB Legacy (option D) configuration files, not UEFI bootloader files, so they are both incorrect. Efi file extension to identify them thus option E is correct. Outlook for mac current versionOption B, the /boot/efi directory, is used to store UEFI bootloader programs, not GRUB configuration files, so it is incorrect. The GRUB Legacy configuration files are stored in the /boot/grub directory, so option A is correct. Option E, ISOLINUX, was also a later bootloader, which lets you boot Linux from a CD or DVD drive. Option D, the SYSLINUX bootloader, provided features for use with Microsoft FAT partitions so that you can boot Linux from a USB memory stick, but it was a later creation and not the first Linux bootloader. The GRUB2 bootloader was a later improvement over the GRUB Legacy bootloader, so options A and C are incorrect. The GRUB Legacy bootloader, despite its name, wasn’t the first bootloader but the second bootloader commonly used in Linux. The GRUB2 bootloader stores configuration files in both the /boot/grub directory and the /etc/grub.d directory, so options B and C are correct. Likewise, Linux uses the /proc directory to provide dynamic kernel runtime data and not configuration files. The /var directory stores variable files, such as log files, but not configuration files, so option D is incorrect. Likewise, the update-rc.d command (option B) is also used to change runlevels for programs on Debian systems, so it too is incorrect. The chkconfig command (option A) is used to check and change runlevels for programs, so it is incorrect. The grub-mkconfig command combines the configurations defined in the /etc/default/grub file and all of the files in the /etc/grub.d folder into a single grub.cfg configuration file. Option E, /var, is used to store variable files, such as log files, and not configuration files, so it is incorrect. Option D, /boot/efi, stores UEFI bootloader program files, not GRUB2 configuration files, so it is also incorrect.
