Which characteristics are representatives of a link-state routing protocol? (Choose three.)
A. provides common view of entire topology B. exchanges routing tables with neighbors C. calculates shortest path D. utilizes event-triggered updates E. utilizes frequent periodic updates
Correct Answers: A, C, D
Each of routers running link-state routing protocol learns paths to all the destinations in its “area” so we can say although it is a bit unclear.
Link-state routing protocols generate routing updates only (not the whole routing table) when a change occurs in the network topology so Link-state routing protocol like OSPF uses Dijkstra algorithm to calculate the shortest path.
Unlike Distance vector routing protocol (which utilizes frequent periodic updates), link-state routing protocol utilizes event-triggered updates (only sends update when a change occurs).
