Answer:
The protocol will drop the packets
The application will automatically re-transmit the packets
Explanation:
Based on design, the routers will drop the packets as allowed by the Internet Protocol, due to the collision that resulted from the router being busy and the network is congested or that the packet is corrupt as indicated by the check sequence of the Ethernet frame or the IPv4 header checksum
Given that the application uses User Datagram Protocol (UDP) which does not allow recovery of lost packets, but have their defined methods of overseeing lost packets, as such the application will re-transmit the packet.
