An organization needs to ensure uninterrupted service of its critical applications in case of a primary system outage. Which of the following actions would best confirm that their systems can handle such an event?
Regularly backing up data to an offsite location
Reviewing disaster recovery plans with key stakeholders annually
Implementing redundant power supplies in the data center
Testing the switch over to backup systems under simulated failure conditions
Testing the switch over to backup systems under simulated failure conditions is the most effective way to confirm that systems can handle a primary system outage. This practice verifies that failover processes work correctly, ensuring continuity of operations. Regular data backups safeguard information but do not test system availability. Reviewing disaster recovery plans is important for preparedness but does not validate the functionality of failover systems. Implementing redundant power supplies helps prevent power-related outages but does not confirm the ability to handle other types of system failures.
