Part AAn organization has a number of tools available when determining how best to address performance issues on their network. The organization can use subnetting or they can use segementation.Part BNetwork use different routing protocols to select the routing path to reach other networks. Adistance-vector routig uses a set of protocols (IPX SPX IP DECnet) and a distance calculation through an outgoing network interface to select the most efficient path to a network destination.Link-state routing protocols track the connection status type to each link that comes from a network. The criteria for selection are links with greater hops and faster mediums. Those are considered the most efficient links that will be used by the routing protocols.
