CompTIA Security+ (SY0-501) — Question 917

An organization handling highly confidential information needs to update its systems. Which of the following is the BEST method to prevent data compromise?

Answer options

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

Correct answer: C

Explanation

Shredding is the best choice as it physically destroys the data storage media, making data recovery nearly impossible. Wiping and degaussing can still leave data vulnerable to recovery, while purging may not completely eliminate all traces of data.
