Question 38

MESH TOPOLOGY ADVANTAGES

Answer 38

1. No data traffic issues as there is a dedicated link between two devices which means the link is onlyavailable forthose two devices. 2. Mesh topology is reliable and robust as failure of one link doesn ’taffect other links and the communication between other deviceson the network.
