While examining a log report you find out that an intrusion has been attempted by a machine whose IP address is displayed as 0xde.0xad.0xbe.0xef. It looks to you like a hexadecimal number. You perform a ping 0xde.0xad.0xbe.0xef. Which of the following IP addresses will respond to the ping and hence will likely be responsible for the intrusion?
Suggested Answer: D

Wait, how does hex even work for IPs?

I agree, option D is invalid.

No way, that can't be a valid IP!

I think it converts to 222.173.190.239.

That's definitely a hex IP address!

I feel like this question is similar to one we did in class about identifying IP addresses from logs. I just can't recall the conversion process clearly.

I think the hex 0xde.0xad.0xbe.0xef translates to something like 222.173.190.239, but I could be mixing it up with another example we practiced.

I remember we discussed how to convert hexadecimal to decimal, but I'm not entirely sure about the exact conversion for this IP.

If I remember correctly, the ping should respond to the decimal equivalent of the hex IP, which might be option D, but that address looks off with those numbers.

The question is asking about listing queued print jobs, so I'm going to go with E. lpq seems like the most logical choice.

Hmm, I'm a bit unsure about this one. I know GPON is a fiber optic network technology, but I'm not super familiar with the specific security methods used. I'll have to think this through carefully.

I've seen questions like this before, so I think I have a good strategy for approaching it. I'll start by considering the different options and eliminating the ones that don't seem relevant.
