What does an IPv4 address configuration use to determine the broadcast address for a specific subnet? MCQ with Answer and Explanation

What does an IPv4 address configuration use to determine the broadcast address for a specific subnet?
A. The external DNS resolution system
B. The loopback hardware interface
C. The network mask and host bit combinations
D. The MAC registration lookup
Answer: Option C
Solution (By JKSSB Mock Tests)
Setting all host bits of an IP network block to binary 1 yields the specific broadcast address used to send data to all devices on that subnet.

Question #1
Which topology design features all client nodes wired directly to a central switch or hub, ensuring that a broken client cable only affects that single node?
A. Ring Topology
B. Linear Topology
C. Star Topology
D. Bus Topology

Correct Answer: Option C


Explanation:
In a star topology, each device connects back to a central switch via an isolated cable run, so a cable break only affects that specific device.

Question #3
What is the maximum number of IP addresses in a Class C network?
A. 65534
B. 256
C. 254
D. 16,777,214

Correct Answer: Option C


Explanation:
Class C has 8 host bits, giving 2^8 = 256 addresses, with 2 reserved (network and broadcast), so 254 usable.
