I'm going with A and D. Can't go wrong with the classic 'route' and 'ip route' commands. Deleting the default gateway is like deleting your emergency contact - it's just asking for trouble!

Haha, 'netstat -r default'? That's just gonna show you the routing table, not delete anything.

E) sysctl ipv4.default_gw=0? Really? I'm not sure that would actually delete the default gateway. Sounds more like a way to change the default gateway.

E) I think you're right, sysctl command is used to change system parameters, not delete the default gateway.

Whoa, 'ifconfig unset default'? That's a new one to me. I've never seen that before.

Yes, those are the right choices. 'ifconfig unset default' and 'netstat -r default' are not valid commands for removing the default gateway.
