What helps ensure data integrity in the event of a catastrophic system failure?

• A. Public key infrastructure (PKI).
• B. Virtual private network (VPN).
• C. Asymmetric encryption.
• D. Routine data backup.

Answer: (D)

Routine data backup is essential for ensuring data integrity in the event of a catastrophic system failure. Regularly backing up data means that copies of information are stored in a secure location, away from the primary system affected by the failure. This practice allows for the restoration of data to its last backed-up state, minimizing data loss and helping to maintain the accuracy and consistency of the information. The backup process ensures that, should a system crash occur due to hardware failure, cyberattack, or any other significant disruption, data can be recovered. While public key infrastructure, virtual private networks, and asymmetric encryption play crucial roles in securing data during transmission and preventing unauthorized access, they do not specifically address the recovery aspect of data integrity after a catastrophic failure. Backups are a proactive strategy focused directly on maintaining the availability and integrity of data against potential loss events.
