What condition happens in a standard unidirectional Ring Topology if a single computer terminal loses power or its cable breaks? MCQ with Answer and Explanation

What condition happens in a standard unidirectional Ring Topology if a single computer terminal loses power or its cable breaks?
A. The network communication loop is broken, stopping data traffic across the entire ring.
B. Data frames flow twice as fast in the opposite direction.
C. The remaining nodes configure themselves into a star topology.
D. The network automatically transitions to wireless transmission.
Answer: Option A
Solution (By JKSSB Mock Tests)
Because data travels sequentially around a unidirectional ring network, any single broken link breaks the circuit and disrupts the entire network.

Which of the following is a broadcast address for a network with subnet mask 255.255.255.0 and network IP 192.168.1.0?
A. 192.168.1.1
B. 192.168.1.0
C. 192.168.1.255
D. 192.168.1.254

Correct Answer: Option C


Explanation:
The broadcast address is the highest address in the subnet, i.e., 192.168.1.255 for a /24 network.

Question #2
In a physical Bus Topology, what happens if the main backbone cable line is cut anywhere along its length?
A. The network splits into two separate, fully functional subnets.
B. All signal termination fails, causing massive signal bounce that disrupts communication across the entire layout.
C. The line switches to half-frequency full-duplex mode.
D. The nearest node transforms into a hub automatically.

Correct Answer: Option B


Explanation:
A sever in a bus network removes proper termination, causing signal reflection that corrupts data traffic for all connected devices.

What notation standard is used to write and display modern 128-bit IPv6 address configurations readably?
A. Binary bitstream flags
B. Dotted decimal fields
C. Base-64 character strings
D. Eight groups of four hexadecimal digits separated by colons

Correct Answer: Option D


Explanation:
IPv6 addresses are formatted as eight groups of four hexadecimal digits separated by colons (e.g., 2001:0db8:0000:0000:0000:ff00:0042:8329).
