Correct answer & explanation
✓
Self-healing of failed containers
Container orchestration platforms like Kubernetes provide self-healing capabilities by automatically restarting failed containers, rescheduling them on healthy nodes, and replacing or terminating containers that fail health checks. This ensures high availability and reduces manual intervention, which is a core benefit of orchestration.
