Refer to the figure. What is the maximum possible throughput obtained end to end on this network when the user on Lab A communicates with the user on LAB D?
The maximum possible throughput is based on the largest connection, the T3.
The maximum possible throughput is based on the smallest connection, the T1. <-----
There is not enough data to determine the maximum possible throughput.
The maximum possible throughput is the T1 plus T3 speed divided by 2.
