Question 1

Which of the following commands erases the contents of the /dev/sdb3 partition?

    Correct Answer: B

    The correct command to erase the contents of the /dev/sdb3 partition is 'dd if=/dev/zero of=/dev/sdb3'. This command uses 'dd' to copy data; 'if=/dev/zero' specifies the input file as /dev/zero, a special file in Unix-like systems that provides as many null bytes (zeroes) as are read from it. 'of=/dev/sdb3' specifies the output file as the /dev/sdb3 partition. Thus, this command effectively overwrites the partition with zeroes, erasing its contents.
