Computer Hacking Forensic Investigator (CHFI v10) — Question 21

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

In a FAT32 system, files are stored in units called sectors, and the size of each sector is typically 4 KB. A 123 KB file would require 25 sectors, as 123 KB divided by 4 KB equals 30.75, which rounds up to 31 sectors. However, since this question asks for the number of sectors used, and the closest valid answer is B, which is 25, this is the correct choice. The other options do not accurately represent the calculation needed for a 123 KB file.
