CompTIA SecurityX (CAS-005) — Question 52

A company is decommissioning old servers and hard drives that contain sensitive data. Which of the following best protects against data leakage?

Answer options

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

Correct answer: C

Explanation

Shredding is the most effective method for physically destroying data on hard drives, making recovery nearly impossible. Purging and clearing do not ensure that data cannot be retrieved, while degaussing is only effective for magnetic media and may not apply to all types of storage devices.
