Haha, 'HPA'? I'm guessing that's some sort of Kubernetes inside joke that the exam writers are trying to slip in there. Nice try, but I'm not falling for that one!

This question is a bit tricky, but I think the key is understanding what types of instances ACK can actually scale. I'd go with A, D, and E for sure. B and C are a bit iffy, in my opinion.

I'm not sure about B and C though, they seem less likely to be scalable.

I agree with Simona's response. Those four options make the most sense. Although, I'm a bit curious about the 'F' option. What's a 'HPA'? Is that something related to Kubernetes auto scaling?

A, D, and E seem like the obvious choices to me. But I'm not sure about B and C. Do bare-metal instances and GPU instances really work with ACK auto scaling?

I'm not sure about Virtual Node. I think it could also be F) HPA for auto scaling.

I agree with Marge. Virtual Node makes sense for auto scaling in ACK.

Hmm, I think A, C, D, and E are the correct answers. ECS, GPU instances, preemptible instances, and virtual nodes can all be scaled using ACK auto scaling.
