What basic operational weakness is shared by both Bus and Star topologies if their respective central shared medium (backbone line or central switch) fails completely?
A. They suffer a single point of failure that can cause total network collapse.
B. They require dynamic analog rewiring steps.
C. They automatically switch to high-frequency multicast mode.
D. They experience an instantaneous duplication of MAC addresses.
Answer: Option A
Solution (By JKSSB Mock Tests)
If the core backbone cable in a bus topology or the central switch in a star topology fails, the entire connected network collapses.
