A logistics firm is planning a new Google Kubernetes Engine (GKE) cluster for an engine routing optimization engine. The application requires custom Linux kernel sysctl settings on the worker nodes to optimize network socket buffers, along with dedicated local NVMe SSD storage attached directly to the underlying virtual machines. Which GKE mode of operation should the team choose to support these infrastructure requirements?
- Deploy a GKE Standard cluster, because only Standard mode allows custom node pool configurations and host OS kernel tuning.Answer
- BDeploy a GKE Autopilot cluster, because Autopilot automatically injects required host OS kernel parameters based on Pod resource requests.
- CDeploy a GKE Autopilot cluster with Spot Pods, because Spot workloads automatically grant node-level administrative privileges for kernel modifications.
- DDeploy a GKE Standard cluster and configure Horizontal Pod Autoscaler (HPA) to manage the underlying Linux kernel settings dynamically.
Answer
Deploy a GKE Standard cluster, as it provides administrative access to custom node pool configurations, specialized disk hardware, and host kernel tuning.
GKE Standard mode allows administrators to create and manage custom node pools with specific hardware types (such as local NVMe SSDs) and modify node OS configurations, including sysctl kernel parameters. Because GKE Autopilot restricts direct node access and custom host OS modifications, Standard mode is required.
