Certified Data Privacy Solutions Engineer (CDPSE) — Question 23

Which of the following is the BEST method of data sanitization when there is a need to balance the destruction of data and the ability to recycle IT assets?

Answer options

• A. Factory reset
• B. Degaussing
• C. Cryptographic erasure
• D. Data deletion

Correct answer: B

Explanation

Degaussing is the most effective method for sanitizing data while allowing for the recycling of IT assets, as it destroys the magnetic field of storage devices, making data recovery impossible. Factory reset and data deletion may not completely remove data, leaving it potentially recoverable. Cryptographic erasure depends on the encryption method used; if not properly implemented, it may also leave data vulnerable.
