Network Topologies

Question 1

Star

Answer 1

Each endpoint node is connected to a forwarding appliance, such as a switch or router. The central node communicates between endpoints.

Question 2

Hub and spoke

Answer 2

Same physical layout as a star topology but used in a different context. Star is often seen in LAN while hub and spoke is often seen in WAN with remote sites.

Question 3

Mesh

Answer 3

Each device has a point-to-point link; giving great fault tolerance. The number of links in a required by a full mesh is expressed as n(n-1)/2 where n is the number of nodes.
