QUESTION 138

Which two statements are true of the OSPF link-state routing protocol? (Choose two.)

 

A.       Using the Bellman-Ford algorithm, each OSPF router independently calculates its best paths to all destinations in the network.

B.       Using the DUAL algorithm, each OSPF router independently calculates its best paths to all destinations in the network.

C.       OSPF sends summaries of individual link-state entries every 30 minutes to ensure LSDB synchronization.

D.       OSPF sends triggered updates when a network change occurs.

E.        OSPF sends updates every 10 seconds.
