Which practice helps ensure data remains accessible during disruptions?

• A. Data Minimization.
• B. Public Cloud Adoption.
• C. Frequent password changes.
• D. Business Continuity Planning.

Answer: (D)

Maintaining data availability during disruptions hinges on planning for continuity. This involves identifying which data and systems are critical, defining how quickly they must be available (recovery objectives), and establishing concrete strategies to keep or restore access when a disruption occurs. Key elements include regular data backups, replication to off-site or alternate locations, redundant hardware and network paths, and automatic or rapid failover to a backup site, all tested regularly to ensure the plan works. With these measures in place, even if the primary environment is down, users can reach the data through secondary infrastructure, reducing downtime and preventing data loss.

Data minimization focuses on reducing the amount of data collected or stored, not on keeping data accessible during outages. Public cloud adoption can help resilience, but it only helps if the cloud environment is configured with proper disaster recovery and redundancy. Frequent password changes improve security, not data availability during disruptions.
