Which of the following correctly represents the association of protocols based on their type?

The correct answer highlights that OSPF (Open Shortest Path First) is a link-state protocol. Link-state protocols operate by having routers share information about their local links with all other routers in the network. Each router constructs a complete view of the network topology by collecting link-state information and uses this to compute the shortest path to each destination using algorithms like Dijkstra's algorithm.

This approach allows OSPF to converge quickly and efficiently handle changes in the network, such as link failures or new routers being added, making it suitable for larger and more complex networks. The classification of OSPF as a link-state protocol is foundational to understanding how it operates and how it compares to distance vector protocols.

Other protocols listed have different characteristics. EIGRP is actually a hybrid protocol that incorporates features of both distance vector and link-state protocols, thereby making the association of EIGRP with link-state incorrect. RIP (Routing Information Protocol) is a distance vector protocol, using hop count as a metric to determine the best path. BGP (Border Gateway Protocol) is classified as a path vector protocol and is used for routing between autonomous systems on the internet, not as a distance vector.
