Which of the following is the MOST effective method of destroying sensitive data stored on electronic media?
Suggested Answer: C Vote an answer
Explanation
The most effective method of destroying sensitive data stored on electronic media is physical destruction, which involves breaking, shredding, melting, or incinerating the media to make it unreadable and unrecoverable. Degaussing, random character overwrite, and low-level formatting are methods of sanitizing or erasing data from electronic media, but they do not guarantee complete destruction of data and may leave some traces that can be recovered by advanced techniques. Therefore, physical destruction is the most secure and reliable method of data disposal for sensitive data.
