"in this method, before transmitting data between two end systems, the network establishes a dedicated end-to-end connection between the end systems and reserves bandwidth in each link along the connection. the reserved connection bandwidth is ""wasted"" whenever the end systems are not sending data."
circuit switching and packet switching
access networks
packet switching
throughput
none of the above

None of the above

Explanation: The mentioned networking situation in question is of circuit switching.This method has the function of establishing the path through circuit  between the nodes and then communication can take place. It is kind of the tradition digital telephone networking based on circuit switching.

Other options are incorrect because packer switching sends the message in the packet form which cannot take place in telephone network,throughput is amount of message that passes through the network and access networks are network that are connected with routers in immediate manner.Thus none of the given options are correct.

hope it

it is much more convenient for the consumer to order something online, rather than going to a store. it saves them time and money for them, especially if that item is not accessed easily.
