Computer Hacking Forensic Investigator (CHFI v10) — Question 445

What do you call the process in which an attacker uses magnetic field over the digital media device to delete any previously stored data?

Answer options

• A. Disk deletion
• B. Disk cleaning
• C. Disk degaussing
• D. Disk magnetization

Correct answer: C

Explanation

The correct answer is C, Disk degaussing, as it specifically refers to the technique of using a magnetic field to disrupt and erase the stored data on magnetic media. Options A and B do not accurately describe this process, while D, Disk magnetization, incorrectly suggests a method that would not erase data but rather alter its magnetic properties.
