The computation of the shortest path in OSPF is usually done by ______

1.	The computation of the shortest path in OSPF is usually done by ____________(a) Bellman-ford algorithm(b) Routing information protocol(c) Dijkstra’s algorithm(d) Distance vector routingThis question was addressed to me during an interview.I'd like to ask this question from OSPF topic in section Network Layer of Computer Network
Answer» The correct choice is (c) Dijkstra’s algorithm Easiest EXPLANATION: Shortest path in OSPF is usually COMPUTED by Dijkstra’s algorithm. It was PROPOSED by Edsger W. Dijkstra in the year 1956. It is a greedy method algorithm and HENCE may not guarantee the shortest path every time, but is really fast.
