In a star topology, usually only one cable fails. The usual effect is:
A. That one device loses connectivity while the others still reach the central switch✓ 答案
B. Every device on the network is permanently disconnected
C. The network automatically becomes a WAN
D. All stored files on each device are deleted
解說
Each device has its own connection to the central switch, so a single cable fault is local to that device. This resilience is one reason star topologies are widely used, though the switch remains a single point of failure.
