Consider a UNIX-I node which has 1 single indirect pointer, 2 double-indirect pointers, and 1 triple-indirect pointers. If DBA is 8 byte and disk block size of 8 KB then what will be the maximum size of the file?
(A) 96 GB
(B) 80 GB
(C) 64 TB
(D) None of these


Answer: (D)

Explanation: Since DBA is 8 byte and and Disk block size is 8 KB.
Number of disk block address = Disk block size / Disk block address size
8 KB / 8 B = 1 K = 210
Triple indirect block address will decide the size of DBA file:
(210)3 * 8 * 210 B = 64 * 240 byte = 8 TB

So, option (D) is correct.
