CompTIA Security+ (SY0-501) — Question 419

A security technician has been assigned data destruction duties. The hard drives that are being disposed of contain highly sensitive information. Which of the following data destruction techniques is MOST appropriate?

Answer options

• A. Degaussing
• B. Purging
• C. Wiping
• D. Shredding

Correct answer: D

Explanation

Shredding is the most appropriate method for data destruction in this scenario because it physically destroys the hard drives, making data recovery nearly impossible. Degaussing and purging are effective but may not completely eliminate data in certain drive types, while wiping only overwrites data, which could still be recoverable with advanced techniques.
