Which characteristics are representative 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
Answer: ACD
Explanation:
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) ->
