CompTIA Security+ (SY0-501) — Question 1036

A company wants to ensure confidential data from storage media is sanitized in such a way that the drive cannot be reused. Which of the following method should the technician use?

Answer options

• A. Shredding
• B. Wiping
• C. Low-level formatting
• D. Repartitioning
• E. Overwriting

Correct answer: A

Explanation

Shredding is the most effective method for ensuring that a drive cannot be reused, as it physically destroys the drive's components. Other options like wiping, low-level formatting, repartitioning, and overwriting may not provide sufficient assurance that data is irretrievable, as they may leave residual data that can be recovered.
