CompTIA A+ Core 2 (220-1102) — Question 650

Which of the following filesystem formats would be the BEST choice to ensure read and write compatibility of USB flash drives across several generations of Microsoft operating systems?

Answer options

• A. APFS
• B. ext4
• C. CDFS
• D. FAT32

Correct answer: D

Explanation

FAT32 is the best choice for cross-compatibility with various generations of Microsoft operating systems because it is widely supported by both older and newer versions of Windows. The other options, such as APFS and ext4, are primarily used in specific operating systems like macOS and Linux, respectively, and CDFS is typically used for CD-ROMs, making them less suitable for USB flash drives.
