Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Bus topology
Why it's wrong here
In a bus topology, devices are connected along a single cable; failure of the cable affects all devices, but failure of a single device may not.
- ✗
Mesh topology
Why it's wrong here
In a mesh topology, each device connects to many others, providing redundancy; a single failure does not take down the whole network.
- ✓
Star topology
Why this is correct
A star topology uses a central switch; if the switch fails, all connected devices lose connectivity.
- ✗
Ring topology
Why it's wrong here
In a ring topology, each device connects to two others forming a ring; failure of one device can disrupt the entire ring.
