Multiple choice

  2. Updates sent at regular intervals

  3. Updates sent only to directly connected neighbors

  4. Updates that include complete routing tables

A Correct answer
Explanation

Link-state routing protocols like OSPF send updates immediately when network topology changes are detected, rather than waiting for periodic update intervals. This event-driven approach allows the network to converge much faster because all routers learn about changes almost simultaneously and recalculate their routing tables. Distance-vector protocols, by contrast, typically wait for scheduled update timers, which delays convergence.
