Explanation
Data remanence refers to data that remains on storage media after it has been deleted (see ISC2 Study Guide, Chapter 5, Module 1). For example, when a file is deleted from a computer's hard drive, the data is not immediately removed. Instead, the space occupied by the file is marked as available for reuse, but the original data can often be recovered using specialized software tools until new data overwrites it. The other options do not precisely define data remanence. Data that has been permanently deleted is not data remanence because it cannot be recovered. Data that has been moved to another storage device is also not an example of data remanence; assuming the data has not been deleted, the data is still being actively maintained, just in a different location. Data that has been encrypted is also not an example of data remanence unless it has been deleted. Moreover, overwriting encrypted data is actually a form of eliminating data remanence
