RIP, or Routing Information Protocol, is designed to share routing information between routers in a local area network. It uses a distance-vector routing algorithm and is characterized by a maximum hop count of 15, which determines network reachability.

The correct choice indicates that RIP sends its routing updates every 30 seconds. This frequency is crucial because it allows routers to adapt to changes in the network. By sending updates regularly, routers can inform one another about changes in network topology or the failed routes, ensuring that all routers maintain an accurate view of the network.

The 30-second update interval helps balance the need for timely network updates with the need to conserve bandwidth. Too frequent updates could overwhelm network resources, especially in larger networks. Conversely, longer intervals could delay convergence, causing temporary routing issues until all routers become aware of changes. Hence, a 30-second interval is considered optimal for maintaining a responsive and efficient routing environment with RIP.
