Final answer:
Dynamic routing protocols are essential for providing routers with current routing tables and involve consuming bandwidth to exchange routing data, thus allowing networks to adapt to changes without manual reconfiguration.
Step-by-step explanation:
The characteristics commonly associated with dynamic routing protocols include b) providing routers with up-to-date routing tables and d) consuming bandwidth to exchange route information. Dynamic routing protocols automatically adjust to changes in the network topology by exchanging routing information between routers. This exchange of information ensures that routers have the latest paths for packet delivery.
Unlike static routing, dynamic routing allows for easier network management but requires some initial configuration on the devices. Moreover, dynamic routes can adapt to network changes without manual intervention but they do involve some amount of consumed bandwidth for the exchange of routing information and necessary processing power to calculate the best paths.
