Answer: Use the Node Auto-Upgrades feature for your GKE cluster.
**Correct Answer: D** - Using the Node Auto-Upgrades feature for your GKE cluster is the most efficient way to keep your cluster updated with the latest Kubernetes versions. This feature automatically upgrades the nodes in your cluster to the latest stable version, ensuring you benefit from the latest fixes and improvements without manual intervention. **Why not the others?** - **A**: Choosing ‘Container-Optimized OS (cos)’ as a node image does not automatically update the Kubernetes version; it only affects the underlying operating system. - **B**: Creating a new cluster with every Kubernetes release is impractical due to the significant migration effort and potential downtime. - **C**: The Node Auto-Repair feature addresses node health issues but does not update the Kubernetes version. For more details, refer to the [Node Auto-Upgrades documentation](https://cloud.google.com/kubernetes-engine/docs/how-to/node-auto-upgrades).
