CompTIA A+ Core 2 (220-1202) — Question 96

Which of the following data destruction methods is most appropriate to ensure that classified information on hard drives cannot be recovered?

Answer options

• A. Overwriting with a software-based secure erase program
• B. Degaussing followed by physical shredding
• C. Formatting with a low-level format tool
• D. Encrypting the drives and storing them securely

Correct answer: B

Explanation

The correct answer is B because degaussing disrupts the magnetic fields on the hard drive, rendering data unrecoverable, and physical shredding ensures any remnants are destroyed. The other options, while providing some level of data protection, do not guarantee complete destruction of classified information as effectively as the combination of degaussing and shredding.
