Which point would score as an advantage of a star over a bus?
A. Fibre is always cheaper than copper.
B. A fault in one link usually affects only one device.✓ 答案
C. A star has no single point of failure of any kind.
D. A star is a type of malware.
解說
One cable in a star serves one device, so that fault stays local. The central switch is still a single point of failure, so option C is too strong. Fibre is a medium, not a topology.
