Haha, D is definitely wrong. One cluster can have multiple scaling groups, not just one. These certification questions really test your Kubernetes knowledge, don't they?

I'm not sure about C, but I think D is incorrect because one cluster can support multiple scaling groups.

I agree with Dahlia. I also think E is correct because scaling group can be defined via a special namespace.

Hmm, B is also correct. The cluster autoscaler will add worker nodes like ECS via AutoScaling when scaling out. Looks like a solid question!

I think A and B are correct because cluster autoscaler can add worker nodes via AutoScaling.

A, C, and E are correct. The cluster autoscaler has different modes to handle scaling out, and it can integrate with different services like ECS to add worker nodes. The swift mode is faster than standard mode, and the scaling group can be defined through a special namespace.
