Selected Answer: B

The recommended approach to ensure a consistent user experience and optimize resource usage for a stateless application with inconsistent traffic in a large Standard Google Kubernetes Engine (GKE) cluster is (option B) Configure a Horizontal Pod Autoscaler (HPA). HPA automatically adjusts the number of replica pods based on observed CPU utilization or other custom metrics. In the context of varying traffic patterns, HPA dynamically scales the number of pods to meet demand, ensuring that there are enough instances to handle increased traffic and scaling down during periods of lower demand. This helps maintain consistent performance while optimizing resource utilization in response to changing workloads.
