Q. Which of the following topologies cannot be used for a local area network ?
✅ Correct Answer: (D)
None of the above
Explanation:
All the listed topologies — Star, Ring, and Bus — can be used for Local Area Networks (LANs).
- Star topology is very common in LANs, where devices connect to a central hub or switch.
- Ring topology has been used in LANs like Token Ring networks.
- Bus topology was used in early LANs with a shared coaxial cable.
So, none of these topologies are excluded from being used in LANs.
