Final answer:
The primary advantage of a point-to-point topology is that data travels on a dedicated link, ensuring a quick and efficient communication between two devices.
Step-by-step explanation:
The main advantage of a point-to-point topology is d. Data travels on a dedicated link. This type of network architecture involves a direct connection between two devices. This direct connectivity ensures that data can move quickly between devices without interference or sharing the medium with other devices, leading to enhanced performance for those two devices.
In point-to-point topology, there isn't a path through which all traffic must pass, as there is no central hub. This setup reduces the chances of bottlenecks and increases the efficiency of data transmission. However, it is important to note that while point-to-point connections provide dedicated links, this does not inherently mean that all information is encrypted, nor does it provide redundancy and fault tolerance. Therefore, options a, b, and c are not correct. While point-to-point networks can be less expensive than other topologies, especially in short distances or for limited connections, the cost efficiency isn't the primary advantage, which excludes option e.
