FC0-U71 Practice Question: A technician is explaining the difference between…

A technician is explaining the difference between volatile and non-volatile memory. Which of the following is an example of volatile memory?

⚠ Common exam trap

Many exam-takers confuse 'memory' with 'storage' and incorrectly assume that any device used to save files (like a USB drive or SSD) is volatile, when in fact volatile memory specifically refers to components like RAM that lose data on power loss.

Correct answer & explanation

✓

RAM

RAM (Random Access Memory) is volatile memory because it requires continuous electrical power to retain data; once the system is powered off, all data stored in RAM is lost. This is in contrast to non-volatile memory, which retains data without power. The question specifically asks for an example of volatile memory, and RAM is the classic example.
