With Centralized Routing, each node must determine and
maintain its routing information independently?
A. True
B. False
Answer / guest
Answer: B
With Centralized Routing, a central node gathers information
about the network, computes the best route from every node
to all possible destinations, and broadcasts the new routes
to all the nodes of the network. The problem with this is
the dense traffic surrounding the central node and the
possibility of a crash of the network due to a failure of
the central node. With Distributed Routing, there is no
central control. Each node must determine and maintain its
routing information independently.
