Suggested Answer:Explanation
Routing Information Protocol (RIP) uses hop count as the metric to rate the value of different routes. The hop count is the number of devices that can be traversed in a route. A directly connected network has a metric of zero; an unreachable network has a metric of 16. This limited metric range makes RIP unsuitable for large networks. The Routing Information Protocol (RIP) sends routing-update messages at regular intervals and when the network topology changes. When a device receives a RIP routing update that includes changes to an entry, the device updates its routing table to reflect the new route. The metric value for the path is increased by 1, and the sender is indicated as the next hop. RIP devices maintain only the best route (the route with the lowest metric value) to a destination. After updating its routing table, the device immediately begins transmitting RIP routing updates to inform other network devices of the change. These updates are sent independently of the regularly scheduled updates that RIP devices send. Summarizing routes in RIP Version 2 improves scalability and efficiency in large networks. Summarizing IP addresses means that there is no entry for child routes (routes that are created for any combination of the individual IP addresses contained within a summary address) in the RIP routing table, reducing the size of the table and allowing the router to handle more routes. It is a stable protocol that uses a distance-vector algorithm to calculate routes.

1. A route can contain no more than 15 hops - YES.
- Routing Protocol RIP its max hop count is 15.
2. Route changes are broadcast immediately through the network - YES
- In addition to the regular transmission of RIP packets every 30 seconds, if a router detects a new neighbor or detects that an interface is unavailable, it generates a triggered update. The new routing information is immediately broadcast out all RIP-enabled interfaces, and the change is reflected in all subsequent RIP response packets.

3. Route management becomes more efficient as the network grows - NO
Reference: https://www.sciencedirect.com/topics/computer-science/routing-information-protocol
4. Routes are calculated based on the number of hops required - YES
- Routing tables in RIP-enabled routers are calculated on the basis of the number of hops to the destination network.
