Which cluster feature allows an administrator to return to the original configuration after a failover?

• A. Load Balancing
• B. Failover Clustering
• C. Failback
• D. Heartbeat Monitoring

Answer: (C)

The feature that allows an administrator to return to the original configuration after a failover is known as failback. When a failover occurs, one node in a cluster takes over the responsibilities of another node that has failed or become unresponsive. Failback is the process of moving the workload back to the original node once it becomes healthy and available again. This ensures that the system can restore its operational state to its initial configuration, allowing for optimized resource usage and minimizing potential performance degradation. In the context of clustering, while features like load balancing help distribute workloads evenly across multiple servers, and failover clustering focuses on maintaining availability during outages, failback specifically addresses the need to revert to the pre-failure state, making it essential for recovery operations. Heartbeat monitoring is used to detect node failures but does not pertain to reverting to a previous configuration.
