Which of the following describes Key Backup And Recovery?

• A. Restoring lost or damaged certificates
• B. Backups of user passwords
• C. Generating new cryptographic keys
• D. Monitoring certificate expiration dates

Answer: (A)

Key Backup and Recovery is about keeping copies of cryptographic keys and certificates so you can restore them if they’re lost or damaged, ensuring you can continue to decrypt, sign, or authenticate as needed. Restoring lost or damaged certificates directly describes that recovery process—getting back the usable keys and certificates after an issue. The other options describe different aspects of PKI: backups of user passwords aren’t about cryptographic keys, generating new keys is about creating fresh keys rather than recovering existing ones, and monitoring expiration dates deals with certificate lifecycle, not backup and restoration.
