SK0-003 · Question #222
When performing a backup, which of the following media types would have no moving parts?
The correct answer is B. Flash. Flash storage media, such as USB drives or SSDs, rely on solid-state electronics and have no mechanical moving parts for data access. In contrast, tape, WORM, and optical media typically involve mechanical components during operation.

Why each option
Flash storage media, such as USB drives or SSDs, rely on solid-state electronics and have no mechanical moving parts for data access. In contrast, tape, WORM, and optical media typically involve mechanical components during operation.
Tape drives use magnetic tape that moves across a read/write head, requiring mechanical components for operation.
Flash memory, which includes devices like USB drives, SD cards, and Solid State Drives (SSDs), stores data electronically in semiconductor cells without any physical moving components. This makes it a media type with no moving parts during backup or data retrieval.
WORM (Write Once Read Many) often refers to optical media or specialized magnetic media, both of which generally involve moving parts to access data.
Optical media, such as CDs, DVDs, and Blu-ray discs, are read and written using lasers while the disc spins, which involves mechanical movement.
