What type of network is defined as a direct, dedicated connection between two routers?

A point-to-point network is characterized by a direct, dedicated connection between two devices, in this case, routers. This type of connection allows for a focused and efficient communication path as there are no intervening devices or shared resources that could introduce latency or packet collisions.

In a point-to-point setup, the routers can communicate directly with each other, making it ideal for scenarios where high-speed and reliable communication is necessary, such as in WAN links where dedicated lines are established. This configuration is especially useful in scenarios requiring constant data transfer, as it provides a stable and consistent connection without the overhead associated with multiple devices communicating on the same network segment.

The other options describe different types of network architectures or communication methods but do not apply here. A broadcast network involves multiple devices sharing the same communication medium, which could lead to congestions and collisions. A multicast setup allows data to be sent to multiple destinations simultaneously, while a shared network indicates that resources are not dedicated to a single connection. Therefore, the characteristics of a point-to-point connection make it the correct type of network for a dedicated link between two routers.
