Which statement best describes CDFS in Windows?

• A. It is a Linux file system
• B. It is Windows' implementation of ISO 9660 for optical discs
• C. It is ext4-compatible
• D. It is a network protocol

Answer: (B)

CD-ROM File System is the driver Windows uses to read optical discs. It provides access to the ISO 9660 standard layout used on CDs and DVDs (and it also supports extensions like Joliet for longer names). This is specifically about optical media handling, not about Linux file systems, not about ext4, and not about network protocols. So describing it as Windows’ implementation of ISO 9660 for optical discs is the accurate, best-fit explanation.
