Q
If 5 files are transferred from server A to client B in the same session. The number of TCP connections between A and B is _______
AA. 5
BB. 10
CC. 2
DD. 6
Correct Answer:
D. D. 6
Explanation:
The client would first initiate the TCP control connection through port 21. Then for every file transfer, a separate connection would be made through port 20. Now, since we have five files to be transferred, 1 control connection + 5 data connections = 6 total TCP connections.
