What Are Two Examples Of Hybrid Topologies?

What are two examples of hybrid topologies? (Choose two.)

• Full mesh.
• Hub and spoke.
• Tree topology.
• Partial mesh.
• Extended mesh.

Answer: A hybrid topology as the name suggests it is the mixture and the combination of the different topologies. The two examples of hybrid topologies are the partial mesh and the extended mesh.

Hybrid topology

A fusion of more than two topologies as the mesh topology, bus topology, and ring topology is known as the hybrid topologies. The use of the hybrid topology is based on the need and the implementation of the destined computer, network, and their positions.

For the implementation of the topology physically man different technologies are used because the physical structure is complex for the hybrid topology. The good thing about topology is that it is flexible and allows other topologies to include or remove easily. For the diversity in the network, a hybrid topology is needed.

The configuration of many other topologies also happens in hybrid topology. such as the hybrid network made with star backbone and the ring network and the star mesh hybrid topology is also used in case the main backbone is failed which destroys the whole network.

Let’s discuss the types of hybrid topologies in the following section:

Star-Ring hybrid topology:

The Star-Ring topology is the combination of the star and the ring topology. with the ring, more than two-star topologies are connected through wires. While in the real ring the data comes at the connecting node. The flow of data is unidirectional or bidirectional. in the original ring, the flow is unidirectional and it does not affect the whole network if a node fails.

Star-Bus hybrid 

The bus ad the star topology forms the star-bus hybrid topology. More than two-star topologies are connected with the bus with wires. The bus topology acts as the backbone of the network and provides the wire structure.

Hierarchical hybrid topology

The hierarchical hybrid topology is also known as the network tree topology the maximin root of it is known as the parent node and the minimum level is known as the leaf nodes. The next level node is the child node at level three.

Hybrid topology pros and cons

Pros:

Some of the pros of the hybrid topology are described in the following section:

• Reliable: It is highly reliable because it has high fault tolerance .in case the node is damaged then it can quarantine the faulty node with the rest of the nodes.
• Effective: in this topology, only the strength of the combined topologies is mattered. the tolerance ability of it is high which is provided by the star topology and the data is reliable in it.
• Between the different topologies, the data transferal is easy to accommodate.

Cons:

• Complexity: with the involvement of different kinds of topology the structure is complex. And the creation of it is very difficult. The configuration of it requires efficiency and thorough knowledge.
• Cost: An equipment and the maintenance of the hybrid topology is expensive, while the structure hubs are used and are quite expensive.
