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

Totally agree, Virtual Nodes are scalable too!

Wait, can Preemptible instances really be auto-scaled?
JE

I think GPU Instances are also scalable.
MA

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 think ECS instances can definitely be scaled, but I'm not sure about the others.

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.
ME

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

I agree, those instances can be scaled by ACK.
ET

I think A, D, and E are the correct options.

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?
LI

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

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

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.
KA

B and F are not instances that can be scaled using ACK auto scaling.
RO

What about B and F?
IZ

I agree, those are the correct answers for ACK auto scaling.
NO
Norah

I think A, C, D, and E are correct.
MA
Marge

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