UDP provides connectionless, fast transport of data at Layer 4.
UDP provides connection-oriented, fast transport of data at Layer 3.
UDP relies on application layer protocols for error detection.
UDP works well when an application does not need to guarantee delivery of data.
UDP relies on IP for error detection and recovery.
UDP provides sophisticated flow control mechanisms.
The packets will be sent to the server because it is a server-based port.
The packets will be sent to Switch2 and not leave the switch because the packets are local.
The packets will be sent to the laptop host.
The packets will be sent to Router1 and dropped because private addresses are not transmitted across the Internet.
The packets will be sent to Router2 and dropped because the server is not directly attached.
