Definitely agree with C! Without it, audio won't cut through.

I think option C is the right one. PRACK is key for provisional responses.

This question looks pretty straightforward. I'll carefully review the configurations and choose the one that best meets the requirements.

Okay, let's see. The malware is trying to beacon out, so the network device logs could be helpful to see the network traffic. But the DNS server logs might also give us some clues about the external site it's trying to connect to. I'll have to weigh the options carefully.

Hmm, I'm a bit unsure about this. I'll have to review my notes on the asset accumulation method to make sure I understand the different asset categories.
