Which statement about volatile data is true?

Which statement about volatile data is true?

• A. Non-volatile Data resides in RAM
• B. Volatile Data can be modified
• C. Transient Data is stored on long-term disks
• D. Residual Data cannot be retrieved

Answer: (B)

Volatile data is information that only exists while power is supplied; it lives in RAM and can change as the system operates. Because RAM is dynamic memory, its contents are continually modified by running programs, so the fact that volatile data can be modified is true. The other statements mislabel where volatile data resides or its recoverability: non-volatile data persists without power and is stored on disks or other long-term storage, not in RAM; transient (volatile) data isn’t stored on long-term disks; residual data from memory or storage can often be recovered with forensic tools, so it isn’t correct to say it cannot be retrieved.
