C is horizontal scaling, not vertical!

I feel like adding more nodes is definitely horizontal scaling, so I guess that means C is out too.

I practiced a similar question where vertical scaling was defined as increasing the capacity of existing resources, which sounds like B again.

I'm not entirely sure, but I remember something about cluster autoscaler being related to horizontal scaling, so that rules out A for me.

I think vertical scaling is about adding resources to a single node, so that might be option B?

This seems like a straightforward configuration task, but I want to make sure I understand the requirements clearly before I start.

Wait, I'm a little confused. Does modifying the action group really solve the problem, or is there something else I'm missing? I'll need to review the question more carefully.
