You have received a default route through BGP from your ISP and you want to redistribute it into OSPF.Which mehtod will accomplish this?() A. Apply an export policy to OSPF that exports the default routeB. Apply an import policy to OSPF that imports the default routeC. Apply the default-network command to OSPFD.

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

Refer to the exhibit. You have completed an OSPF implementation, and you are verifying OSPF operation. You notice that router A and router B are stuck in the two - way state. From the show ip ospf interface command output, what is the cause of this issue?()A. All OSPF implementations must have at le ast one interface in area 0.B. You are attempting to run in the broadcast mode over an NBMA interface.C. Both routers are configured to function as a BDR; therefore, there is no DR router.D. Someone has changed the OSPF router ID; therefore you must clear the OSPF process.E. The OSPF priority is set to 0 on both routers; therefore neither can become the DR.

On your OSPF network, routers TK1 and TK2 belong to the same Ethernet network. However, they are unable to establish an adjacency over this link. While troubleshooting this problem, you issue the show ip ospf interface Ethernet 0command on each router. The output from these commands is displayed below:What is the underlying cause of the routers failing to become adjacent?()A. The OSPF area is misconfigured.B. The priority on TK2 should be set lower.C. The cost on TK2 should be set lower.D. The hello and dead timers are misconfigured.E. You need to add a backup designated router to the network.F. The OSPF process ID numbers do not match.

While troubleshooting some connectivity issues,you issue the “show ip ospf database”in order to ex amine the link state database. Which three of the statements below are true regarding the OSPF link state database()A.Each router has an identical link state database.B.External routes are imported into a separate link state database.C.Syn chronization of link state databases is maintained via floodingo f LSAs.D.Information in the link state database is used to build a routing table by calculating a shortest-path tree.E.By default,link state databases are refreshede very 10 minutes in the absence of topology changes.
