Which of the following describes a use case for a flash drive?

The correct answer is A. A flash drive is a small, portable local storage device, so it is useful when a user needs to copy or back up a local file and carry it to another location, such as home. Option B describes cloud storage. Option C describes network file sharing. Option D describes long-term archiving, which is not the best use case for a flash drive because flash drives are small, easy to misplace, and not ideal as long-term archive media.

Exact Extract/Reference: The CompTIA Tech+ Study Guide defines an external flash drive as “a small, portable SSD that connects through a USB port” and says its “primary benefit is portability.” The guide also lists flash drives as a locally attached backup storage option.
