Question 39

Every device is connected to every other device

In a mesh topology, each device is interconnected, meaning that every device is connected to every other device in the network. This arrangement ensures high redundancy and reliability in communication.

A) All devices are connected to a single central device

This option describes a star topology, not a mesh topology. In a star topology, all devices connect to a central hub or switch, which is not the case in a mesh configuration where each device has a direct connection to all others.

B) Every device is connected to every other device

This option accurately defines mesh topology. In this configuration, each network device has a dedicated point-to-point link to every other device, allowing for multiple pathways for data transmission and enhancing fault tolerance.

C) Devices are connected to a common communication line

This describes a bus topology rather than a mesh topology. In a bus topology, all devices share a single communication line, which is distinctly different from the interconnected nature of a mesh setup.

D) Every device is connected to exactly two other devices

This option represents a ring topology, where each device is connected in a circular fashion to two others. In contrast, mesh topology allows for connections to all other devices, making this description inaccurate.

Conclusion

The correct answer is option B, as it clearly defines the fundamental characteristic of mesh topology where every device is interconnected. The other options describe different topologies, such as star, bus, and ring, which do not align with the definition of a mesh network. Thus, option B is definitively right, while all other options fail to represent the arrangement in a mesh topology.
