What Will Happen in a Tree Topology if the Central Hub Gets Fails?

Answer: In the tree topology if the central hub gets fail the entire system gets fail.

• All the nodes or devices in the tree topology are connected to a central hub.
• The communication and working of the devices is impossible without the central system.
• Therefore if the central hub gets fail, the overall system or the nodes gets fail too.
• If the tree topology has multiple sub branches and any sub branch hub or switch gets fail it will affect only the specific sub nodes or system, rest other sub nodes operates properly.
• Backup central devices or hubs are also available, when the tree networks are designed with redundancy measures. In such case, if one central hub or switch gets fails, the backup system can be used in order to avoid the failure.
• Such failures can have a huge impact on scalability of network and therefore is considered as one of the drawback of tree topology.

Conclusion

In tree topology all the nodes or systems are directly connected to the central system. If the central system fails due to any reason the overall system results into failure.
