A server administrator is testing a disaster recovery plan.

The live failover testing method is the most likely one that the server administrator is performing when creating a downtime scenario and taking the necessary steps. A live failover test involves switching from the primary system to the secondary system (or backup site) in a real environment, without any simulation or preparation. A live failover test can evaluate the effectiveness and readiness of the disaster recovery plan, but it also carries a high risk of data loss, corruption, or disruption.Reference:https://www.ibm.com/cloud/learn/disaster-recovery-testing
