TCP & UDP Questions

Question 1 What is the difference regarding reliability and communication type between TCP and UDP? A. TCP is reliable and is a connection-oriented protocol UDP is not reliable and is a connectionless protocol B. TCP is not reliable and is a connection-oriented protocol; UDP is reliable and is a connectionless protocol C. TCP is not reliable and is a connectionless protocol; UDP is reliable and is a connection-oriented protocol D. TCP is reliable and is a connectionless protocol; UDP is not reliable and is a connection-oriented protocol

A

Question 3 How do TCP and UDP differ in the way they guarantee packet delivery? A. TCP uses checksum, acknowledgement, and retransmissions, and UDP uses checksums only. B. TCP uses two-dimensional parity checks, checksums, and cyclic redundancy checks and UDP uses retransmissions only. C. TCP uses checksum, parity checks, and retransmissions, and UDP uses acknowledgements only. D. TCP uses retransmissions, acknowledgement and parity checks and UDP uses cyclic redundancy checks only.

A

Question 2 How do TCP and UDP differ in the way they provide reliability for delivery of packets? A. TCP is a connectionless protocol that does not provide reliable delivery of data, UDP is a connection-oriented protocol that uses sequencing to provide reliable delivery B. TCP does not guarantee delivery or error checking to ensure that there is no corruption of data UDP provides message acknowledgement and retransmits data if lost C. TCP provides flow control to avoid overwhelming a receiver by sending too many packets at once, UDP sends packets to the receiver in a continuous stream without checking for sequencing D. TCP uses windowing to deliver packets reliably; UDP provides reliable message transfer between hosts by establishing a three-way handshake

C

Question 4 How do TCP and UDP differ in the way that they establish a connection between two endpoints? A. TCP uses synchronization packets, and UDP uses acknowledgment packets B. UDP uses SYN, SYN ACK and FIN bits in the frame header while TCP uses SYN, SYN ACK and ACK bits C. UDP provides reliable message transfer and TCP is a connectionless protocol D. TCP uses the three-way handshake and UDP does not guarantee message delivery
