A network engineer needs to implement a network topology where every device has a direct, dedicated point-to-point link to every other device in the network. Which topology best fits this requirement?
- AStar topology
- BMesh topology
- CRing topology
- DBus topology
Show answer & explanationAnswer & explanation
Correct answer: B. Mesh topology
A mesh topology provides a direct, dedicated point-to-point link between every device in the network. This offers high redundancy and fault tolerance but is typically expensive and complex to implement for a large number of devices.
Why the other options are wrong
- A. In a star topology, all devices connect to a central hub or switch, not directly to each other.
- C. In a ring topology, devices are connected in a closed loop, with each device connecting to exactly two neighbors.
- D. In a bus topology, all devices share a single communication line, not individual point-to-point links.
Network Topologies
Network topologies describe the physical or logical arrangement of connections between nodes in a network.
- Physical topology: How devices are physically connected.
- Logical topology: How data flows between devices.
- Common types: Star, Bus, Ring, Mesh.
Memory trick: Stars point to a center, Buses share a line, Rings form a loop, but Mesh connects Everyone.
