I feel like the issue might be related to the interface settings, but I can't recall if it's GigabitEthernet0/2 or 0/3 that needs the change.

I've got this! The answer is B, chain of custody. Making sure the evidence is properly handled and accounted for from seizure to presentation in court is crucial.

I remember practicing something similar where we had to identify handlers, and I feel like the Operator handler might be the right choice here.

Hmm, I'm not totally sure about this one. I know NAT is used for IP address translation, but I'm not confident that's the right answer here. I'll have to think it through a bit more.

Okay, I think I've got this. The legs of the Fishbone represent the main categories of potential defect sources, like materials, equipment, people, methods, etc. And then along those legs, we list out the specific ways each of those could introduce defects. Sounds straightforward enough.

Staff potential sounds like it would play a part in the internal analysis phase, but I'm not sure how it compares with other options like turnover or shortages.

Haha, I bet the engineer forgot to turn it off and on again! Seriously though, the key is in the IS-IS configuration, not the Layer 2 encapsulation.
