In a network where devices connect through a central hub, which topology best fits?

• A. Star Physical Topology
• B. Mesh Physical Topology
• C. Ring Physical Topology
• D. Bus Topology

Answer: (A)

Devices connecting through a central hub form a star topology. In a star topology, each device has its own direct link to a central node (the hub or switch), so all communications pass through that central point. This setup matches the described scenario where devices connect via a central hub. Other layouts don't fit: a mesh would have many interconnections between devices, a ring forms a closed loop of devices, and a bus uses a single shared cable with devices tapping into it. Star topology is common for LANs because it keeps faults localized to individual links or devices, though the central hub represents a single point of failure.
