What is a common disadvantage of mesh topology?

Mesh topology, while offering several advantages such as redundancy and reliability due to multiple connections between devices, does come with some notable disadvantages. The correct choice highlights that mesh topology can lead to high traffic and costs.

In a mesh network, each device is connected to multiple other devices, which means that data can take several paths to reach its destination. This redundancy can create a significant amount of network traffic, particularly if many devices are trying to communicate simultaneously. As a result, the network may become congested, leading to delays and inefficiencies in data transmission.

Additionally, the requirement for numerous connections and wiring can contribute to increased costs, both in terms of hardware and installation. Maintaining a mesh topology involves more complexity, as managing a larger number of interconnected devices requires more sophisticated network management tools and resources.

These factors combined make high traffic and costs a valid concern when considering a mesh topology, despite its strengths in fault tolerance and reliability.
