What is (are) the method(s) to move data through a network of links and switches ?
Answer: D
The methods are Packet switching and Circuit switching.
In circuit switching, as in the old telephone network, a dedicated path is set up between the two ends before data flows and held for the whole call. In packet switching, as on the Internet, data is cut into packets that travel independently through the switches and share the links with other traffic.
Each alone is only half the answer, and 'line switching' is not a standard switching method.
