Wait, can the cluster autoscaler really handle that much load?

I feel like the Vertical Pod Autoscaler is more about resource allocation per pod, so maybe it's not the best fit for this scenario?

I practiced a similar question where the Horizontal Pod Autoscaler was the right choice, but I’m confused about whether to enable the cluster autoscaler too.

I think enabling the cluster autoscaler is crucial for managing node resources, but I can't recall if it pairs with the Vertical Pod Autoscaler.

I remember studying about the Horizontal Pod Autoscaler, but I'm not sure if it works with static node pools.
