I thought "cpu-stress-2" was using more CPU, interesting!

Just checked, and "cpu-stress-1" is definitely the one.

Totally agree, that pod is a resource hog!

Looks like pod "cpu-stress-1" is the top CPU consumer.

I think the answer involves using `kubectl get pods` with some flags, but I'm confused about how to write just the pod name to the file.

I remember practicing a similar question where we had to find the pod with the highest memory usage. I think we can use `--sort-by` for CPU, but I can't recall the exact command.

I think we need to use `kubectl top pods` to check the CPU usage, but I'm not entirely sure how to redirect that output to a file.

I feel like we might need to use `awk` or `grep` to filter the output after getting the pod list. I hope I remember the syntax correctly!

This looks like a straightforward question about contract law. I'm pretty confident I know the answer, but I'll double-check my notes just to be sure.

I'm pretty confident this is H.323 registration, call control and H.323-to-SIP Interworking. The Cisco Meeting Server is known to have those capabilities.

I feel pretty confident about this question. As long as I work through the calculations methodically, I think I can nail the right answer.

This is an interesting question. I'm not super familiar with the details of application deployment, but I'm going to try to reason through it step-by-step and see if I can figure out the right answer.

I'm a bit confused on this one. I know reliability is important, but I'm not sure if effectiveness, certainty, or precision are actually part of the FASB definition. I'll have to go with my best guess on this.

I think the key here is understanding how VXLAN multicast traffic is handled by the VTEPs. Option C seems to describe that process the best, with the switches performing the encapsulation and decapsulation based on the hashing.
