# What happens when a node in a Kubernetes cluster fails?

Kubernetes, Medium (Advanced), Architecture. https://k8wiz.com/uquiz/what-happens-when-a-node-in-a-kubernetes-cluster-fails

- A. All pods on that node are immediately rescheduled to other nodes
- B. The pods on that node are marked as 'Unknown' and eventually rescheduled if controlled by a controller
- C. The cluster automatically repairs the node
- D. The pods remain on the failed node until manually deleted

**Answer:** The pods on that node are marked as 'Unknown' and eventually rescheduled if controlled by a controller

**Explanation:** When a node fails, the pods running on it are marked as 'Unknown' or 'NotReady'. If these pods are managed by controllers like Deployments or ReplicaSets, new pods will be scheduled on other available nodes to maintain the desired state.
