I thought runsc was still experimental? Not sure about this...

Just a heads up, runsc can impact performance.

Wait, are we really switching all Pods to runsc? Seems risky.

gVisor is a solid choice for added security!

I feel like I’ve seen something similar in our study materials, but I can’t recall the specific commands to apply the RuntimeClass to the namespace.

I'm a bit confused about how to apply the RuntimeClass to existing Pods. Do I need to recreate them or can I just patch them?

I think we did a practice question on updating Pods to use a different runtime. It involved editing the Pod specs, right?

I remember we talked about creating a RuntimeClass, but I'm not entirely sure about the exact syntax for defining it with runsc.

Easy peasy! Just increase the production of the item and let the computer handle the rest. The demand time fence should take care of it.

Okay, I think I've got a strategy for this. I'll need to consider the subscriber's current bounced status and how that interacts with the click event.

This is a good one. I remember learning about the predefined call handlers in Cisco Unity Connection. I think the answer is option C, but I'll double-check the choices to be sure.

Hmm, I'm a little unsure about this one. I'll need to review the details of Regulation T and the exemption criteria to make sure I select the right answer.
