   A network engineer is configuring OSPF on a new router that will connect to an existing OSPF area. The engineer wants the router to discover neighbors and exchange routing information. Which OSPF process must occur first?

   • AThe router sends hello packets on its OSPF-enabled interfaces.
   • BThe router floods its link-state advertisements to all routers in the area.
   • CThe router runs the SPF algorithm to calculate routes.
   • DThe router elects a designated router on all interfaces.

   An OSPF router receives a new link-state advertisement from a neighbor. What is the router's next step in the OSPF process?

   • AIt immediately runs the SPF algorithm and installs new routes.
   • BIt floods the LSA to all other OSPF neighbors and updates its link-state database.
   • CIt sends an acknowledgment and discards the LSA.
   • DIt compares the LSA to its routing table and ignores it if no route changes.

   A network administrator is troubleshooting an OSPF adjacency that is stuck in the ExStart state. The two routers are directly connected and have matching hello/dead timers. What is the most likely cause?

   • AOSPF authentication failure
   • BMTU mismatch on the connecting interfaces
   • CDuplicate OSPF router IDs
   • DMismatched OSPF area ID

   A network engineer is configuring OSPF on a new router that will be added to an existing OSPF area. The engineer wants to ensure that the new router's routes are propagated to all other routers in the area. Which OSPF process must occur after the new router forms an adjacency with a neighbor?

   • AThe new router immediately runs the SPF algorithm and installs routes.
   • BThe new router sends a routing table update to all neighbors.
   • CThe new router floods its LSAs to all neighbors, and they update their link-state databases.
   • DThe new router elects a designated router on all interfaces.

   During OSPF database synchronization, what is the purpose of the Database Description (DBD) packet?

   • ATo acknowledge receipt of LSAs
   • BTo summarize the LSAs in a router's link-state database
   • CTo carry the actual link-state advertisements
   • DTo request specific LSAs from a neighbor
