Which of the following is the GREATEST concern with using degaussing to destroy personal data?

The correct answer is A. It is difficult to verify data destruction. Degaussing works by exposing magnetic media to a strong electromagnetic field to erase stored data. The core problem is that there is no reliable, built-in way to confirm that all data has been fully and irreversibly erased-you cannot read back the drive after degaussing to…

Explanation

Degaussing works by exposing magnetic media to a strong electromagnetic field to erase stored data. The core problem is that there is no reliable, built-in way to confirm that all data has been fully and irreversibly erased-you cannot read back the drive after degaussing to validate destruction. This lack of verifiability is a major compliance concern, especially under privacy regulations (e.g., GDPR) that require documented evidence of lawful data destruction. Options B, C, and D may describe secondary drawbacks but do not represent the primary risk from a data protection and accountability standpoint.
