A. Given a fixed route and fixed link types between two end systems, which of the following delays may vary depending on the level of congestion in the network? Select one: a. processing delay b. propagation delay c. transmission delay d. queueing delay ============================= B. Suppose there is exactly one packet switch between a sending host and a receiving host. The transmission rates between the sending host and the switch and between the switch and the receiving host are R1 and R2, respectively. Assuming that the switch uses store-and-forward packet switching, what is the total end-to-end delay to send a packet of length L? (ignore queuing, propagation, and processing delays) Select one: a. L/(R1+R2) b. (R1+R2)/L c. L/R1+L/R2 d. 2∗(L/R1
