New name servers? Nah, that's not right.

Wait, can ifconfig really change the host name?

The routing table changing? Not so sure about that.

I think IP addresses changing is also a thing.

Network interfaces can definitely go active/inactive.

I’m pretty confident that ifconfig can make interfaces active or inactive, so B is a solid choice. But I don’t think it changes the hostname, so E might be wrong.

I feel like ifconfig might change the routing table too, but I can't recall if that's a direct consequence. C seems possible.

I remember practicing a question where ifconfig affected IP addresses, so I’d go with D for sure. Not sure about A though.

I think using ifconfig can definitely change the status of network interfaces, so B seems right. But I'm not sure about the others.

Hmm, I'm not totally sure about the difference between a Loyalty Ledger and a Transaction Journal. I'll have to think this through carefully.

I think the answer might be RPF, but I'm not completely sure. Didn't we go over this in multicast routing?

This is a good example of a question that requires attention to detail. I'll make sure to double-check my answer before submitting it.
