Multiple Choice

An employee attempts to wipe data from CDs and DVDs with a magnet. CDs and DVDs are ________ media and are not affected by the magnet.

Explanation:
Optical media store data as physical pits and lands read by a laser, not in magnetic domains. Because there is no magnetic layer to erase, a magnet won’t wipe data from CDs or DVDs. This is why magnets work on magnetic storage like hard drives or tapes but not on optical discs. For destroying data on optical discs, you’d need to physically damage the disc or use proper disposal methods, since the data isn’t stored magnetically.
