CISSP Practice Question: An organization requires minimal data loss and rapid recovery for real-time transaction…

Correct Answer: C. A hot site with real-time data replication and automatic failover

Explanation (CISSP Manager Logic):

Real-time transaction systems require near-zero Recovery Time Objectives (RTO) and Recovery Point Objectives (RPO) to prevent catastrophic financial loss. A hot site provides the mirrored infrastructure and automated failover necessary to maintain continuous operations during a major outage.

By implementing this solution, you:

• Minimize data loss through continuous synchronization.
• Reduce downtime via immediate, automated failover.
• Meet high-availability requirements for mission-critical operations.

While the other options are relevant, they fall short because:

• A: Cold sites lack pre-installed hardware and current data, resulting in recovery times of days or weeks.
• B: Weekly synchronization creates an unacceptable RPO, risking several days of lost transaction data.
• D: Cloud backups provide data storage but lack the redundant processing power for immediate failover.

Think like a manager:

Prioritize recovery strategies based on the business impact of downtime. When the cost of an outage exceeds the cost of high-availability infrastructure, a hot site is the only justifiable strategic choice.
