CompTIA A+ Core 2 (220-1102) — Question 474

A technician would like to repurpose hard drives that contain PII. Which of the following would be the best solution to securely remove the data?

Answer options

• A. Drilling
• B. Degaussing
• C. Low-level formatting
• D. Incinerating

Correct answer: C

Explanation

Low-level formatting is the most suitable option for securely removing data since it effectively rewrites the drive's sectors, making data recovery nearly impossible. Drilling and incinerating destroy the drive physically but are not practical for repurposing. Degaussing can be effective but is not always applicable to all types of drives, especially solid-state drives.
