What is the arrangement of network devices in a mesh topology?

Rationale

Every device is connected to every other device.

In a mesh topology, each device is directly connected to all other devices in the network, allowing for multiple paths for data to travel, thus enhancing reliability and fault tolerance.

A (Every device is connected to exactly two other devices.) YOUR ANSWER

This describes a ring topology rather than a mesh topology. In a ring topology, each device connects to exactly two other devices, forming a closed loop. This configuration does not provide the multiple pathways characteristic of a mesh arrangement.

B (All devices are connected to a single central device) YOUR ANSWER

This statement refers to a star topology, where all devices connect to a central hub or switch. In a star topology, if the central device fails, the entire network can go down, contrasting with the redundancy offered in a mesh topology.

C (Devices are connected to a common communication line) YOUR ANSWER

This describes a bus topology, where all devices share a single communication line to transmit data. While this configuration is simpler and less expensive, it lacks the direct interconnectivity that defines a mesh topology, which allows for greater reliability and data redundancy.

D (Every device is connected to every other device) CORRECT

This accurately describes mesh topology. In this configuration, each device communicates directly with every other device, ensuring that data can be routed through multiple paths. This setup significantly increases fault tolerance since the failure of one connection does not disrupt the entire network.

Conclusion

A mesh topology is characterized by every device being interconnected, which facilitates robust communication and redundancy. This contrasts with other topologies such as ring, star, and bus, each of which has distinct connection patterns and vulnerabilities. The direct interconnection of devices in a mesh network enhances reliability and performance, making it suitable for critical applications where uptime is essential.
