2.1-3 UDP service. When an application uses a UDP socket, what transport services are provided to the application by UDP? Check all that apply. 2.1-3 UDP service. When an application uses a UDP socket, what transport services are provided to the application by UDP? Check all that apply.Throughput guarantee. The socket can be configured to provide a minimum throughput guarantee between sender and receiver.O Loss-free data transfer. The service will reliably transfer all data to the receiver, recovering from packets dropped in the network due to routerbuffer overflow.Flow Control. The provided service will ensure that the sender does not send so fast as to overflow receiver buffers.Real-time delivery. The service will guarantee that data will be delivered to the receiver within a specified time bound.Best effort service. The service will make a best effort to deliver data to the destination but makes no guarantees that any particular segment ofdata will actually get there.Congestion control. The service will control senders so that the senders do not collectively send more data than links in the network can handle.O O 0

Answer) Correct option -> Option 5) Best effort service Explanation-> UDP (User Datagram Protocol) is a protocol that is used for data transportation in form of data packets in a network. UDP has the ability to provide fast and easy delivery of packet from sender to the destination. This mechanism makes UDP a best effort service. It does not guarantee the time for delivery of data packet as well as does not assure about delivered data quality but makes best effort to deliver the data packet to the destination. Therefore, Option 5 is the correct option. UDP does not possess the mechanism of reliable data packet transfer from the source to destination as it has chances of delivering data with missing data segments at the destination port. It also does not support the services such as congestion control, real-time delivery flow control, throughput guarantee and loss-free transfer of data. Hence, all the other options are incorrect.
