To ensure that your Google Kubernetes Engine (GKE) cluster always runs a supported and stable version of Kubernetes, you should:
Option C. Select the latest available cluster version for your GKE cluster.
Explanation:
When you create a GKE cluster, you can select the version of Kubernetes you want to run on your nodes. GKE supports a range of Kubernetes versions, and new versions are regularly released with bug fixes, security updates, and new features.
To ensure that your cluster is running the most stable and supported version of Kubernetes, you should always select the latest available version when creating your cluster. This will ensure that your cluster is up to date with the latest bug fixes and security patches, and that you can take advantage of the latest features and functionality.
Option A. Enable the Node Auto-Repair feature for your GKE cluster.
Node Auto-Repair is a feature that automatically repairs nodes in a GKE cluster if they fail health checks. This can help to ensure that your cluster is always running smoothly and can recover from failures quickly. However, this feature does not ensure that your cluster is running the most stable and supported version of Kubernetes.
Option B. Enable the Node Auto-Upgrades feature for your GKE cluster.
Node Auto-Upgrades is a feature that automatically upgrades the nodes in a GKE cluster to the latest available version of Kubernetes. This can help to ensure that your cluster is running the most up-to-date version of Kubernetes and can take advantage of the latest features and functionality. However, this feature may not always ensure that the latest version is stable and supported.
Option D. Select Container-Optimized OS (cos) as a node image for your GKE cluster.
Container-Optimized OS (COS) is a lightweight operating system designed specifically for running containers. It is optimized for running Kubernetes workloads and includes all the necessary components for running containers, such as Docker and the Kubernetes runtime. While COS is a good choice for running containers, it does not guarantee that your cluster is running the most stable and supported version of Kubernetes.
