1. 1.Which two statements are reasons why UDP is used for voice and video traffic instead of TCP? (Choose
two.)
TCP requires all data packets to be delivered for the data to be usable.
The acknowledgment process of TCP introduces delays that break the streams of data.
UDP does not have mechanisms for retransmitting lost packets.
UDP tolerates delays and compensates for them.
TCP is a connectionless protocol that provides end-to-end reliability.
UDP is a connection-oriented protocol that provides end-to-end reliability.
Scoring Rule For: correctness of response
Option 2 and Option 3 are correct.
1 point for each correct option.
0 points if more options are selected than required.
Max Value = 2
2. Why is TCP the preferred Layer 4 protocol for transmitting data files?
TCP is more reliable than UDP because it requires lost packets to be retransmitted.
TCP requires less processing by the source and destination hosts than UDP.
UDP introduces delays that degrade the quality of the data applications.
TCP ensures fast delivery because it does not require sequencing or acknowledgements.
