What is the main weakness of a star topology?
AWiring cost is the highest of all the topologies
BData can travel in only one fixed direction
CA single break in the backbone stops all traffic
DFailure of the central device can down the network
Answer & Solution
Correct answer: D. Failure of the central device can down the network
1. In a star, every device connects to one central node such as a hub or switch.
2. That makes it effective and fast, since each device has a direct link to the centre.
3. A disturbance in one device will not affect the rest of the network.
4. But any failure in a central networking device may lead to the failure of the complete network.
5. High cabling cost belongs to mesh, one-way traffic to ring, and the shared backbone to bus.
