I recall that if no loopback is configured, it might choose the highest active interface instead, but I can't remember if that's relevant here.

I'm not entirely sure, but I feel like there was a practice question that mentioned something about using the highest IP for the router ID.

That makes sense to me. The question is specifically about the Product Selection page, so the products shown should be limited to those with pricing in the relevant currency.

I'm a bit confused by the details here. The question mentions a lot of specific technologies that I'm not super familiar with. I'll need to review my notes and maybe look up some additional information to feel confident in my answer.

I'm pretty sure the answer is C. The `kubect1 get version` command should show the Kubernetes version running on the cluster.

Okay, let's think this through step-by-step. The question is asking for the selling price per unit, and we know the company uses marginal cost plus pricing with a 40% margin. So we need to calculate the marginal cost and then add 40% to get the selling price.
