Node A wants to find MAC address of node B$,$ which is not in its ARP table. Which $2$ of the following are correct?

Question $1$ options:

Node A broadcasts ARP query message, containing B$\text{'}$s IP address, asking for its MAC address.

Address pair $($IP$-$to$-$MAC$)$ will stay in the ARP table forever, so the nodes do not have ever to use broadcast channel again.

All nodes in the LAN now save B$\text{'}$s IP$-$to$-$MAC address pair in their ARP table.

ARP is 'plug$-$and$-$play', meaning the nodes create their ARP tables without intervention from net administrator.
