: Explanation:
Explanation / Answer
Good Wishes,
1. Answer is option C. LILO
Explaination:One of the most powerful aspects of Linux concerns its open method of starting and
stopping the operating system, where it loads specified programs using their particular configurations,
permits you to change those configurations to control the boot process, and shuts down in a graceful and
organized way.Beyond the question of controlling the boot or shutdown process, the open nature of Linux
makes it much easier to determine the exact source of most problems associated with starting up or shutting
down your system. A lot of Linux systems use lilo, the LInux LOader for booting operating systems.
2. Answer is option C./var/log
Explaination:
One can view log files in linux by opening the terminal or login as root user using 'ssh' command.
You can go to /var/log directory using 'cd' command as follows
# cd /var/log
3. Answer is option B. Master Boot Record(MBR)
Explaination:
The basic input/output system(BIOS) locates the boot loader program on a Linux system by reading
the Master Boot Record(MBR) on the hard disk. Usually BIOS checks the floppy drive for bootable media,
if present and then it looks to the hard drive for a Master Boot Record(MBR) starting at the first sector
on the first hard drive, loads its content into primary memory and gives the control to it.
4. Answer is option D. File Allocation Table(FAT)
Explaination:
EFI relies ona special type of partition called EFI System Partition(ESP), to hold EFI specific data.
Generally it uses FAT32 filesystem, but some Linux distributions use FAT16.
5. Answer is option D. Grand Unified Boot Loader 2 (GRUB2)
Explaination:
GRUB 2 is the default boot loader and manager for Ubuntu since version 9.10 (Karmic Koala).
As the computer starts, GRUB 2 either presents a menu and awaits user input or automatically transfers
control to an operating system kernel. GRUB 2 is a descendant of GRUB (GRand Unified Bootloader). It has
been completely rewritten to provide the user significantly increased flexibility and performance.
GRUB 2 is Free Software.
Hope this is clear.
