Wait, does this mean I can have a 'polar bear' in my PolarDB cluster? I'm going with B, just to be on the safe side.

This question is making me feel a bit 'polar-ized'. I'll go with A, just to keep things simple.

Ha! I bet the developers were feeling a bit 'polar' when they set the max at 15. I'm sticking with D just to see what happens.

Wait, 15 read-only nodes? That sounds like a lot. I'm going to go with C, 10 seems more reasonable for a PolarDB cluster.

Hmm, this seems like a tricky one. I'm guessing the answer is B, since 5 is a nice round number for a cluster, right?

Exactly, it's not 5. It's 10 read-only nodes in a PolarDB cluster.

I think the answer is actually C) 10, because PolarDB clusters can have up to 10 read-only nodes.
