The " Test Failover " feature in Nutanix Disaster Recovery is a critical tool for ensuring that a BCDR plan is actually functional before a real disaster occurs. The primary goal of a test failover is to validate the entire recovery orchestration—including power-on sequences, script execution, and network mappings—in a completely non-disruptive manner.

During a test failover, the virtual machines are recovered at the destination site using the most recent snapshots, but they are typically connected to an " Isolated " or " Test " network. This allows the administrator to log into the recovered VMs and verify that the application starts correctly without causing any IP address conflicts or interference with the live production systems at the primary site. Unlike a " Planned Failover " or " Unplanned Failover, " a test failover does not move the production workload (negating Option B) and does not stop ongoing replication (negating Option D). It is purely a validation task designed to identify gaps in the Recovery Plan, such as missing dependencies or incorrect network assignments, thereby providing confidence that the organization ' s RTO and RPO goals can be met during a real emergency.
