In a physical Bus Topology, what happens if the main backbone cable line is cut anywhere along its length? MCQ with Answer and Explanation

In a physical Bus Topology, what happens if the main backbone cable line is cut anywhere along its length?
A. The nearest node transforms into a hub automatically.
B. The network splits into two separate, fully functional subnets.
C. The line switches to half-frequency full-duplex mode.
D. All signal termination fails, causing massive signal bounce that disrupts communication across the entire layout.
Answer: Option D
Solution (By JKSSB Mock Tests)
A sever in a bus network removes proper termination, causing signal reflection that corrupts data traffic for all connected devices.

Question #1
What structural problem occurs in a standard Ring Topology if a single node device or its physical connection cable breaks?
A. Data collision drops to zero across the layout.
B. Traffic flows twice as fast in the opposite direction.
C. The entire network communication loop is broken and goes down.
D. The broken node converts itself into a router automatically.

Correct Answer: Option C


Explanation:
In a basic unidirectional ring topology, token signals pass sequentially through each machine. A single break disrupts the entire communication loop.
