[All Professional Cloud DevOps Engineer Questions]

You deployed an application into a large Standard Google Kubernetes Engine (GKE) cluster. The application is stateless and multiple pods run at the same time. Your application receives inconsistent traffic. You need to ensure that the user experience remains consistent regardless of changes in traffic. and that the resource usage of the cluster is optimized.

What should you do?

AConfigure a cron job to scale the deployment on a schedule.

BConfigure a Horizontal Pod Autoscaler.

CConfigure a Vertical Pod Autoscaler.

DConfigure cluster autoscaling on the node pool.

Definitely, the HPA is the clear winner here. Although the cluster autoscaling option might work as well, it's overkill for this scenario and would involve more complexity than necessary.

Yeah, the HPA is definitely the way to go. A cron job to scale the deployment on a schedule wouldn't be flexible enough to handle the inconsistent traffic, and the Vertical Pod Autoscaler is more for scaling the resources of individual pods, not the overall deployment.

I agree, the HPA sounds like the most appropriate solution here. It can dynamically scale the number of pods up and down based on the resource utilization, which should help maintain a consistent user experience even with fluctuating traffic.

Hmm, this seems like a tricky one. The question is asking how to ensure consistent user experience and optimize resource usage in a GKE cluster with inconsistent traffic. I'm leaning towards the Horizontal Pod Autoscaler (HPA) option, as that seems like the best way to automatically scale the number of pods based on the traffic demand.
