When modern key material is destroyed, what status is it reported as?

• A. Decommissioned
• B. Zeroized
• C. Inactive
• D. Obsolete

Answer: (B)

When modern key material is destroyed, it is reported as "zeroized." This term refers specifically to the process of rendering cryptographic keys unusable by overwriting them with zeros or a similar method, thereby ensuring that they cannot be retrieved or used for unauthorized access. The concept of zeroization is critical for maintaining the integrity and security of communications, especially in situations where sensitive information must be protected from potential breaches.

Other terms have different meanings in the context of security. For instance, "decommissioned" typically refers to equipment or systems that are no longer in use but may still exist in some capacity. "Inactive" suggests that something is not currently operational but does not imply its destruction. "Obsolete" indicates that something is outdated or no longer in circulation without necessarily involving its destruction or security implications. Therefore, "zeroized" is the precise term used to indicate that key material has been securely destroyed, making it the correct choice.
