Which of the following is a method for protecting information?

• A. Back up data
• B. Delete all files
• C. Share passwords openly
• D. Disable backups

Answer: (A)

Backing up data is a key way to protect information. When you create copies of important files and store them in a separate location, you can recover them if the original data is lost, corrupted, or made unavailable by hardware failure, accidental deletion, or a cyberattack like ransomware. This safety net helps maintain data integrity and business continuity, because you can restore recent versions and minimize downtime.

In contrast, deleting all files destroys information rather than protecting it. Sharing passwords openly creates a security breach and increases the risk of unauthorized access. Disabling backups removes the safeguard that makes recovery possible after an incident. So backing up data stands out as the practical method for safeguarding information.
