Question #1
What happens if a single computer loses power or its connection cable breaks in a standard unidirectional Ring Network configuration?
A. The network splits into two fully operational sub-rings.
B. The remaining devices shift to a bus topology configuration automatically.
C. The entire network communication path is broken, stopping traffic across the ring.
D. Data frames loop back through the gateway interface.

Correct Answer: Option C
