When learning a new route, if a LSA received is not found in the topological database, what will an internal OSPF router do?() A. The sequence numbers are checked, and if the LSA is val id it is entered into the topology database.B. The LSA is placed in the topological database and an acknowledgement is sent to the transmitting router.C. The LSA is dropped and a message is sent to the transmitting router.D. The LSA is flooded imme diately out of all the OSPF interfaces, except the interface from which the LSA was received.
You have completed an OSPF implementation, and you are verifying OSPF operation. During this verification, you notice that the OSPF route of 172.16.10.0 is repeatedly appearing and disappearing from the routing table. Further investigation finds that the OSPF CPU utilization is very high and the routers are constantly performing SPF calculations. You determine that 172.16.20.2 is the source of the 172.16.10.0 route. Using the show ip ospf database router 172.16.20.1 command, you notice that when this show command is performed repeatedly, the contents of the LSA change every few seconds.What could be the cause of this problem?（）A. OSPF authentication errors between some of the routersB. Two routers have the same OSPF router IDC. Issues with mistuned OSPF timersD. OSPF LSA pacing issues between some of the routersE. OSPF neighbor adjacency problems between some of the routers
For the accompanying router output, which of the following statements describes the stat e that neighbor 172.16.254.3 is in?() A. The router will not accept connections from the peer.B. BGP can exchange routing information in this state.C. The router is listening on its server port for connection requests from the peer.D. The router ha s sent out an active TCP connection request to the peer.
According to RFC 2328, what is the stateful order in which an OSPF router transitions to a full adjacency with a neighbor router?() A. Down, Init, 2 - Way, Exstart, Exchange, Loading, and FullB.

Which of the following data structures exist on a router for the OSPF routing protocol？（）A、OSPF topology tableB、OSPF interface tableC、OSPF routing information baseD、OSPF link-state databaseE、OSPF adjacency tableF、OSPF neighbor table
What are the two benefits of graceful restart？（）A、Graceful restart allows session information recovery without disruption to the network.B、A node can perform a graceful restart to help a neighbor recover its state. The label bindings are kepton state information， which helps the failed node recover faster and does notaffect the current for wardtraffic.C、Graceful restart allows a node to recover state from its neighbor when there is no RP or before thedevice undergoes SSO.D、Graceful restart does not allow session information recovery.E、During a graceful restart， the router removes any stale prefixes after a timer for stale entries expires
