CompTIA CASP+ (CAS-004) — Question 450

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. Cleaning
• C. Shredding
• D. Degaussing

Correct answer: C

Explanation

Shredding is the most effective method for ensuring that data cannot be recovered from hard drives, as it physically destroys the storage medium. While purging, cleaning, and degaussing can help in reducing data accessibility, they do not guarantee complete destruction like shredding does.
