Consider the network illustrated in Figure $1\mathrm{.}16.$ Assume the two hosts on the left of the figure start transmitting packets of $1500$ bytes at the same time towards Router B$.$ Suppose the link rates between the hosts and Router A is $4-$Mbps$.$ One link has a $6-$ms propagation delay and the other has a $2-$ms propagation delay. Will queuing delay occur at Router A$?$
