Which network topology has all devices connect to a central node or hub, with the hub acting as a server?

• A. Star topology
• B. Spanning Tree Protocol
• C. Spoofing (ARP)
• D. Spyware

Answer: (A)

In a star topology, every device connects directly to a central hub or switch. The central device manages traffic between all devices—data from one device goes to the hub, and the hub forwards it to the destination. This setup makes the central node the coordinating point for the network, effectively serving as the data exchange hub. If the central device fails, the whole network is affected, which is a key trade-off of this layout.

The other options aren’t topologies. Spanning Tree Protocol is a protocol used to prevent loops when there are multiple paths in a network. ARP spoofing is a security attack that tricks devices into sending data to the wrong MAC address. Spyware is malicious software.
