What structural issue creates a single point of failure hazard in a standard network Star Topology configuration?
A. A break in any single client cable drops the entire network.
B. If the central hub or switch fails, all connected devices lose network connectivity.
C. MAC addresses can conflict across ports automatically.
D. The endpoint terminators can burn out.
Answer: Option B
Solution (By JKSSB Mock Tests)
Because all devices in a star topology connect back to a central switch or hub, a failure in that central device disconnects the entire network.
