Which characteristics are typical of a link-state routing protocol? (Select three)

Provides a common view of the entire topology
Exchanges routing tables with neighbors
Calculates the shortest path
Utilizes event-triggered updates

The correct answer is: Provides a common view of the entire topology

The characteristics of a link-state routing protocol indeed encompass several important aspects, making the correct selection crucial for understanding how these protocols function. A link-state routing protocol provides a common view of the entire network topology to all routers in the area. This means that each router constructs a complete map of the network by exchanging link-state advertisements (LSAs) with its neighbors, allowing every router to understand the network's structure in its entirety. Additionally, these protocols calculate the shortest path to a destination using Dijkstra’s algorithm, based on the data collected from the LSAs. This ensures that the best possible route is selected for data transmission, which enhances efficiency and reliability in the network. Link-state protocols also utilize event-triggered updates to disseminate changes in the network. Instead of regularly broadcasting their entire routing table, they only send updates when the topology changes, which reduces unnecessary traffic and optimizes bandwidth usage. Overall, the selection accurately captures the core principles of how link-state routing protocols operate and interact with the network.
