Hello segan,
Thank you for sharing your thoughts on this item.
The question specifically asks about the pricing options the company should consider, not the exact implementation details of scaling. That’s why the answer choice simply mentions “Spot instances.” It doesn’t need to explicitly say “Spot Fleet,” because in practice, Spot scaling in Amazon EKS is typically implemented through Auto Scaling groups with Spot capacity pools, not necessarily Spot Fleet. The key point is that Spot capacity provides the most cost‑optimized way to handle predictable bursts in demand compared to On‑Demand or Dedicated Instances.

I hope this helps! Let us know if you need further assistance.
