Answer: A
In mesh configuration, devices are connected with many
redundant interconnections among network nodes, thereby,
yielding the greatest redundancy in the event that one of
the nodes fail, in which case network traffic can be
redirected to another node. In star configuration, each
station is linked to the main hub. The main hub establishes
the connection between stations by message or line
switching. Therefore, failure of a node results in the
disruption of the network. In ring configuration, all nodes
are connected to one another?forming a circle; therefore,
the failure of a node results in the disruption of the
network. In bus configuration, all devices are linked along
one communication line with two end points called the
backbone; therefore, the failure of a node results in the
disruption of the network.
