events will occur if connectivity with the other host is unsuccessful? (Choose two.)The command will display all the successful hops a packet makes before it is lost.

The command will calculate the time between successful and unsuccessful packets.

The host on which the command is run will send a UDP request message to the other host.

The command helps to determine where a packet was lost on the path from the source to the destination.
