You are backing up a server with a 1 Gbps link and a latency of 2 ms. Which two statements about
the backup are true? (Choose two.)
A.
The bandwidth delay product is 2 Mb.
B.
The default TCP send window size is the limiting factor.
C.
The default TCP receive window size is the limiting factor.
D.
The bandwidth delay product is 500 Mb.
E.
The bandwidth delay product is 50 Mb.
Explanation:
1 Gbps is the same as 1000 Mbps, and 1000Mb x .0002 = 2 Mbps. With TCP based data
transfers, the receive window is always the limiting factor, as the sender is generally able to send traffic at line rate, but then must wait for the acknowledgements to send more data.
What 2 Mbps does it mean in that particular case? It’s mean if i start transfer a big file speed of transmition will increase with delaying 2Mbps, for example 0 Mbps, 100, 200, … 1000 Mbps (without delay), 0, 98, 198, 998 Mbps with delay?
