Which of the following commands will set the default runlevel of a Linux system?
systemctl --default runlevel5.target
systemctl set-default runlevel5.target
systemctl --set-default runlevel5.target
systemctl set-init runlevel5.target

solution:

this situation is called an ip conflict.

data from a server is sent in small bits called packets. in an ip conflict, some packets will end up in one computer while some other packets will end up in another computer.

so…overall none of the computers get the data as the original message or picture being sent by the server cannot be retrieved with only half the packets. so it will show up as an error.

thus the final answer is d.
