Question 34 2 points Save A Consider the network in the figure below. Host A Host B Host A and Host B are connected by a single 4 Mbps (Megabits per second) link that has a propagation delay of 25 ms (milliseconds). Host A sends a 3000-byte packet starting at time t=0. At what time (in ms) is the packet fully received by Host B (i.e., what is the end-to-end delay)? Question 35 2 points Save Answe A host inside the odu.edu domain needs to determine the IP address of www.cs.unc.edu.
