Computer Hacking Forensic Investigator (CHFI) — Question 16

In a FAT32 system, a 123 KB file will use how many sectors?

Answer options

• A. 34
• B. 25
• C. 11
• D. 56

Correct answer: B

Explanation

A FAT32 file system typically uses a sector size of 512 bytes. To determine the number of sectors used by a 123 KB file, you calculate 123 KB (or 125,952 bytes) divided by 512 bytes per sector, which equals 246 sectors. However, since sectors must be fully allocated, you round up to the nearest whole sector, which is 25 sectors for 123 KB. The other options are incorrect as they do not accurately reflect the allocation required for the file size.
