SK0-003 · Question #186
A WORM drive can be equated to which of the following common technologies?
The correct answer is B. CDR. A WORM drive, which allows data to be written once and read many times without modification, is functionally equivalent to a CD-R disc.

Why each option
A WORM drive, which allows data to be written once and read many times without modification, is functionally equivalent to a CD-R disc.
A CD-RW (Compact Disc ReWritable) allows data to be written, erased, and rewritten multiple times, which contradicts the WORM principle of write-once.
A CD-R (Compact Disc Recordable) allows data to be written onto it only once, after which the data becomes permanent and can be read multiple times but not erased or altered, which precisely defines the WORM (Write Once, Read Many) technology.
Flash Media, such as USB drives or SD cards, is designed for multiple writes and erasures, making it a rewritable storage medium rather than a WORM medium.
A DVD-RW (Digital Versatile Disc ReWritable) is a rewritable optical disc format, enabling data to be written, erased, and rewritten many times, unlike WORM technology.
