Which of the following describes the three major types of LAN configuration topologies?

The three major types of LAN configuration topologies are star, bus, and ring. In a star topology, all devices are connected to a central hub or switch, which acts as a repeater for data flow. This design allows for easy management and better fault tolerance; if one device fails, it does not affect the others.

In a bus topology, all devices share a single communication line or cable, known as the bus. While this topology is easy to set up and requires less cable than a star configuration, it can be more challenging to troubleshoot; if the bus fails, the entire network can go down.

The ring topology connects each device in a loop, where data travels in one direction around the ring. This structure can lead to consistent data transmission times, although it presents issues such as a single point of failure – if one device or connection goes down, data cannot complete the circuit.

In contrast, other options do not correctly identify the primary topologies used in local area networks. The mesh topology, for instance, while it represents a strong and resilient connection method, is not one of the three fundamental types primarily discussed in basic networking. Additionally, the optical and hybrid topologies mentioned in other options include elements that are not part of the traditional
