Not sure about EBM, seems like a stretch for auto-scaling.

Wait, can Preemptible instances really be auto-scaled?

ECS can definitely be auto-scaled.

I believe Virtual Nodes are part of the scaling options, but I’m a bit confused about HPA and its role in this context.

Wasn't there something about bare-metal instances being less flexible? I can't recall if they support auto scaling.

I remember practicing a similar question, and I feel like GPU instances might also be scalable.

I'm pretty sure the answer is FATAL, since that's the most critical log level and should always be enabled by default.

I seem to recall something about redirecting users away from harmful sources as a protective measure, but I might be mixing that up with another topic.

I'm a little confused by the wording of the question. I'll need to re-read it a few times to make sure I understand what they're asking.

Hmm, I'm a bit unsure about this one. I know electronic evidence needs to be handled carefully, but I'm not sure I can confidently identify all the key characteristics. I'll have to think this through.

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?

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.

I think the correct answer is E) Virtual Node because it can be scaled by Alibaba Cloud Container Service for Kubernetes (ACK) auto scaling.
